How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns extracted C2PA manifest data including signer identity, creation tool, timestamps, provenance assertions, AI-generation flags, and a cryptographic audit record with chain hashing for tamper-evidence. If no manifest is present, indicates the image lacks content credentials.
Example use cases
AI-generated image detection for newsroom
“I need to verify whether this photo we received has any C2PA provenance data — can you inspect it and tell me if it shows signs of being AI-generated or if there's a verified human creator attached? URL: https://newsagency.com/submitted-photo.jpg”
Content credentials check for social media post
“Before we share this image on our platform, can you check if it has C2PA metadata embedded? I want to know who signed it and whether it has intact content credentials: https://uploads.example.com/user-image.png”
Brand asset provenance audit
“We're auditing our licensed image library for authenticity — can you inspect this TIFF file for C2PA manifest data so I can see the full provenance chain and verify it hasn't been tampered with? https://assets.brandvault.com/licensed/hero-image.tiff”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/c2pa-inspectWhen to prefer
Use this endpoint when you need to verify the authenticity and provenance of an image according to the C2PA standard, especially for trust-and-safety workflows, newsroom fact-checking, AI-generated content detection, or any scenario where knowing the origin, creator, and editing history of an image matters. It is purpose-built for C2PA manifest extraction with an auditable cryptographic record, making it preferable to generic EXIF readers or metadata extractors that do not understand the C2PA trust hierarchy.
Side effects
- Image URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the image
- Unsupported image format (e.g. GIF, BMP, SVG) — returns format error
- Image has no embedded C2PA manifest — returns empty or null manifest result
- URL resolves to a non-image resource — parsing error or format rejection
- Network timeout fetching large image files — request timeout error
- Malformed or corrupted C2PA manifest in the image — parsing failure with error details
