# POST /v1/scan

Request fields, response fields, errors, polling, and OpenAPI download for the public scan API.

Source URL: https://trymighty.ai/docs/api-reference/v1-scan

The stable public API surface is:

- `POST /v1/scan`
- `GET /v1/scan/{scan_id}`

Use the docs below for humans. Use [OpenAPI YAML](/openapi/mighty-api.yaml) for SDK generation, AI tools, and contract inspection.

Illustration: One endpoint returns the route your product can enforce. Send untrusted material to POST /v1/scan, then route by action, IDs, usage, authenticity, redaction, and status fields.

## Authentication

Use bearer auth.

```http
Authorization: Bearer $MIGHTY_API_KEY
```

Keep the key on your server.

## Request Fields

If you want plain-language examples before reading every field, start with [Choose Scan Settings](/docs/concepts/configs).

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `content` | string | Text JSON only | Text or base64 payload. |
| `file` | file | Multipart only | Uploaded image, PDF, or document. |
| `reference_content` | string | No | Optional base64 reference/source image for `content_type=image` + `focus=edits` pairwise manipulation review. |
| `reference_file` | file | Multipart only | Optional reference/source image upload for pairwise `focus=edits` review. |
| `reference_file_path` | string | Self-hosted only | Optional local reference/source image path for pairwise `focus=edits` review. |
| `content_type` | string | No | `auto`, `text`, `image`, `pdf`, `document`. Default `auto`. |
| `scan_phase` | string | Yes | `input` or `output`. |
| `mode` | string | No | `fast`, `secure`, `comprehensive`. Default `secure`. |
| `focus` | string | No | Purpose selector and image-unit billing input: `steg` for threats and hidden content, `ai` for authenticity/provenance, `edits` for localized image manipulation evidence, or `all` for every supported evidence family at 10 SCU per image unit. Focused image paths are 4 SCU. Default `steg`. Office and structured documents support `steg` only. `standard` and `both` are deprecated aliases. |

| `data_sensitivity` | string | No | `standard`, `tolerant`, `strict`. Default `standard`. |
| `scan_group_id` | UUID | Output scans | Required when `scan_phase=output`. Omit on the first input scan if you want Mighty to generate it. |
| `session_id` | string | No | Stable workflow or chat session ID. Omit if you want Mighty to generate it. |
| `request_id` | UUID | No | Use for idempotency and logs. |
| `async` | boolean | No | Requires `mode=comprehensive` and image or PDF. |
| `webhook_url` | string | Async only | Requires `async=true`. |
| `metadata` | object | No | String values for app correlation. |
| `stop_on_first_threat` | boolean | No | Stops early when supported. |
| `defer_enhance` | boolean | No | Supported with secure mode. |

## Focus Purpose

`focus` controls which evidence family Mighty prioritizes. It does not change your tolerance or routing thresholds. Use `profile`, `data_sensitivity`, and your own policy for that.

For practical examples like user prompt inspection, image authenticity review, and original-vs-submitted image comparison, see [Choose Scan Settings](/docs/concepts/configs#focus-modes-without-jargon).

| Focus | Purpose | Runs | Use when | Avoid when |
| --- | --- | --- | --- | --- |
| `steg` | Threat and hidden-content detection. This is the default safety path. | Text/OCR safety, credential checks, hidden-surface OCR, file/PDF hidden-text checks, visual injection checks, and steganography-style forensic signals where supported. | Uploaded material can reach an AI system, OCR/IDP pipeline, reviewer workflow, chat attachment flow, or document intake process. Benign hidden text can become `WARN`; malicious hidden instructions can escalate to `BLOCK`. | You only need AI-authenticity or localized edit evidence and do not want unrelated safety signals. |
| `ai` | Authenticity and provenance review. | AI-generated or AI-edited evidence signals, provenance state, artifact evidence, component status, and reviewer explanations when available. | Claims, KYC, marketplace, receipt, screenshot, and provenance workflows where the main question is whether the visible evidence appears AI-generated, AI-edited, reposted, or inconsistent. | The content can contain text, OCR, hidden instructions, secrets, or visual prompt injection that might reach a model. Use `steg` or `all` instead. |
| `edits` | Localized image manipulation review. | Pairwise source-to-candidate edit localization when `reference_file`, `reference_content`, or `reference_file_path` is supplied; conservative no-reference artifact review otherwise. | You need review evidence around changed pixels, edited labels, altered document text in an image, food contamination edits, package changes, screenshots, or claim photos. | You need threat scanning or authenticity provenance at the same time. Use `all` instead. |
| `all` | Combined evidence review. | Threat and hidden-content checks, AI authenticity/provenance, and localized edit evidence where the modality supports them. | High-value image/PDF intake, AI-facing uploads, claims, or any flow where cross-family evidence matters. Add `reference_file` when you have the source image. | Office/structured document scans; use `steg` for those until document authenticity and edit-localization pipelines are available. |

Authenticity and edit evidence are review signals, not fraud proof. A visible object such as mold, damage, hair, a changed label, or altered text is not fraud proof unless evidence and case context support that conclusion.

## Focus Compatibility

For product-facing guidance on which focus to choose, see [Choose Scan Settings](/docs/concepts/configs#focus-modes-without-jargon).

| Content type | Effective focus values | Notes |
| --- | --- | --- |
| `image` | `steg`, `ai`, `edits`, `all` | Full focus support. Add `reference_file`, `reference_content`, or `reference_file_path` for pairwise edit localization. |
| `pdf` | `steg`, `ai`, `all` where available | PDF scans run through the vision/PDF path. Localized image edit review is for image submissions. |
| `document` | `steg` | DOCX, XLSX, PPTX, CSV, Markdown, JSON, XML, and similar structured documents currently run threat and hidden-content detection only. `focus=ai`, `focus=edits`, `focus=all`, and deprecated alias `focus=both` return `400` with `code=unsupported_focus_for_content_type`. |
| `text` | `steg` | Text scans are threat/safety scans. Other focus values are accepted for compatibility but do not add AI-authenticity or edit evidence. Use `profile` and `data_sensitivity` for tolerance. |

## Reference-Aware Image Edits

For `content_type=image`, `focus=edits` and `focus=all` can run in two different ways:

- With `reference_file`, `reference_content`, or `reference_file_path`, Mighty compares the known source image to the submitted candidate image and returns pairwise edit localization evidence.
- Without a reference image, Mighty runs conservative single-image artifact checks. This can still surface review evidence, but it should not be treated as high-certainty proof of a small edit.

Use pairwise mode whenever your workflow has an original, source listing photo, prior claim image, document scan, receipt, screenshot, or user-owned reference.

```bash
curl -X POST https://gateway.trymighty.ai/v1/scan \
  -H "Authorization: Bearer $MIGHTY_API_KEY" \
  -F "file=@./candidate-food-photo.jpg" \
  -F "reference_file=@./original-food-photo.jpg" \
  -F "content_type=image" \
  -F "scan_phase=input" \
  -F "mode=secure" \
  -F "focus=edits"
```

Localized edit evidence is review evidence. A visible object such as mold, damage, hair, a changed label, or altered text is not fraud proof unless the edit evidence and case context support that conclusion.

}
```

| Field | Notes |
| --- | --- |
| `action` | `ALLOW`, `WARN`, or `BLOCK`. The only field you switch on for routing. |
| `risk_score` | Numeric score 0–100. Higher means riskier. |
| `risk_level` | One of `MINIMAL`, `LOW`, `MEDIUM`, `HIGH`, `CRITICAL`. Always returned. |
| `threats` | Array of objects: `{category, confidence?, evidence?, reason}`. Empty when clean. `confidence` is not guaranteed in public production responses. |
| `scan_id` | Use for logs, audit, polling, and review. |
| `scan_group_id` | Connects related scans (input → output, file → OCR text). |
| `request_id` | Correlates one request through your logs. |
| `session_id` | Connects a longer workflow (chat session, claim case). |
| `scan_status` | One of `pending`, `complete`, `failed` — distinct from `action`. |

### Threat object

| Field | Type | Notes |
| --- | --- | --- |
| `category` | string | Threat family — e.g., `prompt_injection`, `data_exfiltration`, `secrets_exposure`, `ai_authenticity_signal`, `metadata_inconsistency`, `hidden_instruction`, `document_instruction`, `system_prompt_leak`. |
| `confidence` | number 0–1 | Optional detector confidence for this individual threat. Public production responses may omit it after response sanitization. |
| `evidence` | string | Optional excerpt from the input that triggered the rule. Not always present. |
| `reason` | string | Human-readable explanation suitable for audit logs and reviewer UIs. |
| `scan_status` | `complete`, `pending`, or `failed`. |
| `preliminary` | `true` when async returns an early result. |
| `page_results` | Per-page PDF or document results when returned. |
| `authenticity` | AI or authenticity signals when returned. |
| `authenticity.ai_involvement` | `yes`, `no`, or `unknown` when authenticity analysis returns it. |
| `authenticity.verdict` | Evidence verdict such as `likely_ai_generated`, `likely_not_ai_generated`, or `indeterminate`. |
| `authenticity.confidence` | Confidence for the authenticity signal when available. |
| `authenticity.signals` | Object of named public authenticity signals, not an array. Keys can grow over time. |
| `authenticity.signals.authenticity_outcome` | Public authenticity outcome such as `verified_ai_provenance`, `likely_ai_content`, `likely_ai_content_in_screenshot`, `localized_ai_edit_suspected`, `localized_edit_suspected`, `likely_human_edited`, `indeterminate_review`, `no_ai_evidence`, or `indeterminate`. |
| `authenticity.signals.pairwise_delta_gate` | Reference-aware edit-delta metrics when a `reference_*` image is supplied for `focus=edits`. |
| `authenticity.artifact_evidence` | Sanitized visual artifact evidence. Localized edit evidence is advisory review evidence, not fraud proof. |
| `authenticity.edited_region_hints` | Bounding-box hints for localized manipulation review when `focus=edits` or `focus=all` returns edit evidence. |
| `authenticity.explanation` | Production-safe reviewer summary with `label`, `review_recommended`, `reason_codes`, `evidence_summary[]`, and `limitations[]`. |
| `authenticity.components` | Production-safe component statuses such as provenance, authenticity checks, artifact review, document checks, and optional visual review. |
| `forensics` | Image or document forensic signals when returned. |
| `redacted_output` | Safer output when available. |
| `scu_charged` | SCU charged for this scan when returned. Mode controls latency/depth; focus controls image-unit billing. |
| `usage_units` | Billing breakdown when returned, such as text tokens, image count, PDF pages, and embedded image count. Counts are physical units, not fractional billing multipliers. |
| `total_pages` | PDF or document page count when returned. |
| `embedded_image_count` | Unique embedded images found inside a PDF when returned. These are deduped before counting. |

Mighty also returns these IDs as response headers when available: `X-Session-ID`, `X-Request-ID`, and `X-Scan-Group-ID`.

### Public response sanitization

Public production responses are sanitized for stability and privacy. Internal model diagnostics, dense timing breakdowns, raw provider internals, and some per-detector confidence fields may be omitted even when they exist inside Mighty. Treat optional fields as optional, including `threats[].confidence`, `timings`, `processing_ms`, and low-level authenticity diagnostic fields.

Use `action`, `risk_score`, `risk_level`, `threats[].category`, and the sanitized `authenticity` fields for product routing and reviewer display. Do not depend on raw detector internals, private provider names, or every scan returning the same evidence keys.

## Actions, Categories, And Tags

Treat these fields as separate layers:

- `action` is the workflow decision your app switches on.
- `threats[].category` explains why risk was raised.
- `authenticity` explains file origin, visible content origin, provenance, artifact evidence, and component status.
- Derived category lists in UIs are display summaries. The source of truth in the API is still `threats[].category`.
- `authenticity.signals.authenticity_outcome` is an authenticity outcome, not a fraud verdict and not the same thing as your human review outcome.
- `timings` explains where latency went. Timings are diagnostic, not risk evidence.

### Action Tags

| Tag | Meaning | Product effect |
| --- | --- | --- |
| `ALLOW` | No material risk crossed policy thresholds for this scan. | Continue the workflow and store IDs/evidence for audit. |
| `WARN` | Evidence is suspicious, incomplete, conflicting, or needs review. | Add friction, request more evidence, or send to review. Do not treat as proven fraud. |
| `BLOCK` | A high-confidence threat or policy violation was found. | Stop automation, redact when available, or require manual handling. |

### Threat Categories

These are common `threats[].category` values. The list can grow over time; clients should display unknown categories safely instead of failing closed.

| Category | Meaning | Product effect |
| --- | --- | --- |
| `prompt_injection` | Text or OCR contains instructions that try to override an AI system, tool, reviewer, or policy. | Block or review before the content reaches AI or automation. |
| `ai_prompt_injection` | The text-safety layer found malicious or instruction-overriding intent. | WARN or BLOCK depending on confidence and corroborating evidence. Review benign business context before blocking. |
| `data_exfiltration` | The input asks a model, tool, or agent to reveal private context, credentials, system prompts, or customer data. | Block when it targets secrets or protected data. Review if quoted as training or policy material. |
| `secrets_exposure` | API keys, private keys, tokens, connection strings, credentials, or similar secrets were detected. | Block or redact. Rotate exposed credentials according to your incident process. |
| `pii_detected` | Names, addresses, IDs, medical numbers, financial identifiers, or similar personal data were found. | Depends on `data_sensitivity`. Tolerant business workflows may allow ordinary PII; strict workflows should block. |
| `visual_injection` | Text or patterns inside an image can become instructions after OCR or visual extraction. | Review or block before OCR output enters a model or automated tool. |
| `hidden_text_injection` | Hidden, low-contrast, invisible, off-page, or extraction-only text appears to contain instructions. | Block or route to review; preserve the original file for audit. |
| `pdf_hidden_text` | PDF text exists outside normal visible reading order or visibility expectations. | Review document provenance and extracted text before trusting OCR, IDP, or model summaries. |
| `document_attack` | A PDF or office document carries risky instructions, suspicious structure, or unsafe extraction content. | Review the document and scan extracted text with the same `scan_group_id`. |
| `task_drift` | A later message or output diverges from the original allowed task or workflow intent. | Review session context, reset the workflow, or require a fresh trusted input. |
| `multi_turn_attack` | Risk emerges across a session rather than one isolated message. | Keep `scan_group_id` and `session_id` connected; review the sequence. |
| `obfuscation_detected` | Encoding, Unicode tricks, spacing, homoglyphs, or formatting appear designed to hide meaning. | Review normalized text and combine with semantic or regex evidence before routing. |
| `ai_image_authenticity` | Image provenance, metadata, visual artifacts, or repost analysis raised AI-origin or edit evidence. | Route as authenticity review evidence. It is not a standalone fraud conviction. |
| `metadata_inconsistency` | Container, EXIF, C2PA, compression, or file history signals conflict with the claimed origin. | Supporting evidence only; weak metadata must not block alone. |
| `forensics_stego` | Image or document forensics found hidden payload or unusual bit-plane/container evidence. | Review or block depending on confidence and whether hidden instructions or payloads are recoverable. |

### Authenticity Outcomes

`authenticity.signals.authenticity_outcome` summarizes public authenticity evidence for reviewer UX. It is open-ended; clients should display unknown values safely.

| Outcome | Meaning | Product effect |
| --- | --- | --- |
| `verified_ai_provenance` | Signed provenance validates an AI generation or edit action from a trusted provider. | Strong AI-origin evidence; still not a fraud conviction by itself. |
| `likely_ai_content_in_screenshot` | The file may be a screenshot, repost, or recapture, but the visible content has AI-origin support. | Review as transformed or laundered AI evidence. |
| `localized_ai_edit_suspected` | Synthetic or edited evidence appears localized to a region. | Review the region; do not label the whole file AI-generated solely from this. |
| `likely_ai_content` | Available signals support likely AI-generated or AI-edited visible content. | Route to review or add friction based on your workflow. |
| `indeterminate_review` | Evidence is weak, missing, conflicting, or suspicious enough for review. | Ask for more evidence or route to human review. |
| `no_ai_evidence` | Available evidence does not support AI involvement. | Continue the workflow if other risk layers are clean. |
| `indeterminate` | Available evidence is insufficient for a stronger outcome. | Treat as neutral unless your workflow requires stronger proof. |

### Authenticity Fields

The authenticity object intentionally separates file provenance from visible content.

| Field or tag | Meaning | Product effect |
| --- | --- | --- |
| `source_file_origin` | How the file appears to have been created or captured: `camera`, `os_screenshot`, `physical_recapture`, `pdf_render`, `generated_file`, or `unknown`. | Explains the source surface. Camera origin does not prove the depicted event is true. |
| `visible_content_origin` | What the visible pixels appear to depict: `likely_real`, `likely_synthetic`, `likely_ai_edited`, `likely_human_edited`, `camera_ai_enhanced`, or `indeterminate`. | Use for image authenticity review and evidence requests. |
| `provenance_validation_state` | Validation state for signed provenance or marker evidence. | Shows whether provenance is verified, missing, degraded, conflicting, or marker-only. |
| `ai_to_ai_laundered_suspected` | AI content appears transformed through screenshot, resize, crop, recompression, recapture, or redraw. | Review as transformed AI evidence even when original metadata is gone. |
| `camera_ai_enhanced` | A camera-origin image may include computational photography such as HDR, denoise, sharpening, or night mode. | Do not call this fraud by itself. Treat it as source context. |
| `artifact_evidence[]` | Localized or global visual evidence such as malformed text, logo anomaly, reflection inconsistency, or localized edit. | Use as review evidence. Localized evidence should not automatically label the whole file AI-generated. |

### Explanation And Components

`authenticity.explanation` is meant for reviewer UI copy without exposing raw scanner internals.

| Field | Meaning |
| --- | --- |
| `label` | Human-readable explanation of the authenticity result. |
| `review_recommended` | Whether the evidence should be sent to review. |
| `reason_codes[]` | Stable-ish public reason codes. Unknown values should be displayed safely. |
| `evidence_summary[]` | Short evidence items with `kind`, `label`, optional `confidence`, and optional `component`. |
| `limitations[]` | Reasons evidence may be incomplete, such as missing provenance or optional visual review not completing in budget. |

`authenticity.components[]` explains which sanitized checks ran.

| Field | Meaning |
| --- | --- |
| `name` | Public component name, such as `Provenance`, `Authenticity checks`, `Artifact review`, `Document checks`, or `Visual review`. |
| `role` | Short description of what the component checks. |
| `status` | `completed`, `not_applicable`, `skipped_budget`, `unavailable`, `timed_out`, or `error`. Values can grow over time. |
| `evidence_count` | Count of public evidence items attributed to the component. |

### Provenance Validation States

The public state vocabulary can grow. Current responses may include legacy/product-facing states such as `verified`, `raw_marker_only`, and `provenance_missing`, plus lower-level sanitized states such as `not_checked`, `not_available`, `not_present`, `present`, `present_unverified`, `present_valid`, `present_invalid`, `valid`, `invalid`, `trusted`, `trusted_valid`, `trusted_invalid`, `untrusted`, `unsupported`, `error`, or `unknown`.

| State | Meaning | Product effect |
| --- | --- | --- |
| `verified` | Signed provenance validates the active manifest and signer chain inside policy. | Strong origin evidence. If the manifest says AI-generated, treat as strong positive AI evidence. |
| `raw_marker_only` | Raw C2PA/JUMBF or provider marker strings were found without full signed validation. | Context only. Needs stronger corroboration before changing action. |
| `timestamp_untrusted` | The manifest exists but timestamp trust is incomplete or weak. | Show degraded provenance; do not fail the scan solely for this. |
| `revocation_unchecked` | Signer revocation could not be checked inside budget. | Do not block the fast path; expose the degraded validation state for audit. |
| `manifest_conflict` | Multiple provenance manifests or active-claim signals disagree. | Review the original file and transformed variants. |
| `provenance_missing` | No signed provenance was found or it did not survive transforms. | Neutral. Missing provenance does not prove real or fake. |
| `not_checked` / `not_available` | Provenance validation was not run or the capability was unavailable. | Neutral capability state; route from other evidence. |
| `present_unverified` / `present_valid` / `present_invalid` | A manifest or marker was present with a sanitized validation result. | Use as provenance context, with invalid or unverified states needing corroboration. |
| `trusted` / `trusted_valid` / `trusted_invalid` / `untrusted` | Signer/provider trust status after validation where available. | Stronger than raw marker text, but still combine with visible content evidence. |
| `unsupported` / `error` / `unknown` | Validation could not produce a stronger state. | Do not block solely from this state. |

### Visual Artifact Evidence

`authenticity.artifact_evidence[]` items commonly include `type`, `confidence`, `component`, and `details`. Localized items may also include fields such as `bbox`, `bbox_source`, `bbox_target`, `region`, or `score` when safe to expose. Unknown fields should be preserved for logs and displayed defensively in reviewer tooling.

| Artifact type | Meaning | Product effect |
| --- | --- | --- |
| `logo_anomaly` | Brand marks, badges, or symbols look malformed, melted, asymmetric, or inconsistent. | Supports AI-origin or edit review, especially for vehicle, document, and brand evidence. |
| `malformed_text` | Visible text has impossible characters, broken labels, inconsistent spacing, or OCR-resistant artifacts. | Supports synthetic or tampered-content review. |
| `geometry_inconsistency` | Lines, perspective, object boundaries, or repeated structures do not obey normal scene geometry. | Supports image authenticity review. Not a fraud conclusion by itself. |
| `reflection_inconsistency` | Reflections, shadows, glass, chrome, or lighting disagree with the scene. | Useful for car, property, product, and document-photo review. |
| `texture_repetition` | Surface texture repeats or smooths in ways common to generated or heavily transformed images. | Supporting evidence; combine with authenticity checks and provenance. |
| `damage_physics_inconsistency` | Impact marks, cracks, dents, debris, or deformation do not align with plausible physical damage. | Route to claims review; not a final liability decision. |
| `subpixel_grid` | Screen capture, display recapture, or flattened repost surface evidence is present. | Explains source origin. It should not warn alone without suspicious visible-content evidence. |
| `screen_recapture_moire` | A camera likely photographed a screen, often creating moire, pixel-grid, or refresh artifacts. | Preserve as recapture evidence and review displayed content separately. |
| `paper_texture` | A camera likely photographed printed paper. | Usually a benign source cue. Document truth still needs document-fraud checks. |
| `localized_edit` | A specific region carries stronger manipulation or AI-origin evidence than the rest of the file. | Review the region and avoid over-labeling the whole image. |

### Component Status And Timing Tags

| Tag | Meaning | Product effect |
| --- | --- | --- |
| `completed` | The component ran inside budget and returned evidence. | Use its evidence normally. |
| `skipped_budget` | The component did not have enough residual latency budget. | Do not treat as evidence for or against AI origin. |
| `timed_out` | A bounded component started but did not finish before the deadline. | Show the timeout and route from completed local evidence. |
| `unavailable` | A scanner capability or provider was not available at runtime. | Return a capability state. Text scans may still work when vision is unavailable. |

## Billing Fields

SCU starts at `$0.001`. `mode` controls scan depth and latency. `focus` controls image evidence billing.

Focused image evidence starts at 4 SCU per image for `focus=steg`, `focus=ai`, and `focus=edits`. All-evidence image review is 10 SCU per image unit for `focus=all` and deprecated `focus=both`.

For PDFs, page work and embedded image work are separate usage units. Pages stay 2 SCU each. Unique embedded images use the active focus image-unit price.

```text
Focused PDF SCU = pages * 2 + unique embedded images * 4
All-evidence PDF SCU = pages * 2 + unique embedded images * 10
```

Focused PDF response fields:

```json
{
  "content_type_detected": "pdf",
  "total_pages": 1,
  "embedded_image_count": 4,
  "scu_charged": 18,
  "usage_units": {
    "doc_pages": 1,
    "embedded_image_count": 4
  }
}
```

This means a one-page focused PDF with four unique embedded images bills 18 SCU: 2 for the page plus 16 for the images. The same PDF with `focus=all` bills 42 SCU: 2 for the page plus 40 for the images. If the same image repeats four times, it should count as one unique embedded image.

## Modality And AI Context

Use `content_type` for the material itself:

| Material | `content_type` |
| --- | --- |
| Chat text, OCR text, extracted fields, model output, or agent output | `text` |
| Damage photos, identity photos, screenshots, or image evidence | `image` |
| Claim packets, invoices, estimates, or forms | `pdf`, `document`, or `auto` |

Use `focus=steg` for text, mixed file intake, and structured documents. Use `focus=all` when known image/PDF evidence needs hidden-content, AI-authenticity, and edit evidence together. Use `focus=edits` for advisory image manipulation localization without threat scanning. Use `profile=ai_safety` for public model output and agentic systems.

Use metadata for app context:

```json
{
  "metadata": {
    "workflow": "claims_intake",
    "ai_involved": "true",
    "submitted_as_ai_generated": "unknown"
  }
}
```

These metadata values are supplied by your app. They are not fraud verdicts.

## AI-Generated And Authenticity Signals

Mighty does not return a single top-level `is_ai_generated` boolean. Use the `authenticity` object when it is returned.

Your app may send `metadata.submitted_as_ai_generated` when a submitter self-declares origin. That value is app context, not a Mighty verdict.

Example authenticity signal:

```json
{
  "authenticity": {
    "ai_involvement": "yes",
    "verdict": "likely_ai_generated",
    "confidence": 0.78,
    "evidence_modality": "image",
    "summary": "AI involvement is likely based on visual consistency signals.",
    "signals": {
      "authenticity_outcome": "likely_ai_content",
      "ai_suspicion_score": 0.78,
      "review_recommended": true,
      "review_reason_codes": ["visual_inconsistency"]
    },
    "explanation": {
      "label": "AI involvement is likely based on visual consistency signals.",
      "review_recommended": true,
      "reason_codes": ["visual_inconsistency"],
      "evidence_summary": [
        {
          "kind": "artifact",
          "label": "malformed_text",
          "confidence": 0.72,
          "component": "artifact_localization"
        }
      ],
      "limitations": ["No verified provenance manifest was available."]
    },
    "components": [
      {
        "name": "Authenticity checks",
        "role": "Image-origin and visible-content consistency checks",
        "status": "completed",
        "evidence_count": 1
      }
    ]
  }
}
```

Route this as evidence. `likely_ai_generated`, `likely_not_ai_generated`, and `indeterminate` should influence review and workflow friction. Do not tell users Mighty proves fraud by itself.

## Redaction

`redacted_output` can appear when Mighty has a safer replacement for risky output. Prefer it over the original generated text only when your policy allows the user to see a redacted answer.

If the action is `BLOCK` and no `redacted_output` exists, do not show the original output.

## Poll Async Result

```bash
curl https://gateway.trymighty.ai/v1/scan/$SCAN_ID \
  -H "Authorization: Bearer $MIGHTY_API_KEY"
```

## Error Handling

See [Error Handling](/docs/integrate/errors) for `400`, `402`, `409`, `413`, `429`, and async states.

## AI-Agent Prompt

### Use the API reference

```text
Use the Mighty API reference to implement a server-side integration.

Endpoint:
- POST https://gateway.trymighty.ai/v1/scan
- GET https://gateway.trymighty.ai/v1/scan/{scan_id}

Rules:
- Use bearer auth from MIGHTY_API_KEY.
- Use scan_phase=input for submitted material.
- Use scan_phase=output for generated or extracted output.
- Reuse scan_group_id for related scans.
- Route ALLOW, WARN, BLOCK.
- Store scan_id, request_id, scan_group_id, and session_id.
- Handle 400, 402, 409, 413, 429, pending, complete, and failed.

Read /openapi/mighty-api.yaml before writing typed client code.
