# Camera-Provenance Check

`POST /v1/tools/check_camera_provenance`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/check_camera_provenance`
- Auth: none declared

Structural check on an IDV/KYC capture's C2PA manifest: claim well-formedness, hard-binding hash assertion, and claim-signature reference (art-123 reuse), plus a digitalSourceType read off the c2pa.actions assertion that flags trainedAlgorithmicMedia so a downstream reader knows the capture was declared AI-generated rather than a live camera capture. Structural check only, no trust-list or chain-of-trust claim. Feeds the session receipt builder's capture-chain field (art-359).

**Tool URL:** https://ainumbers.co/chaingraph/art-361-camera-provenance-check.html
