How this service works
Generates SHA-256 cryptographic authenticity digests and C2PA-compliant provenance manifests for verifiable media preservation.
Output
Returns a SHA-256 cryptographic digest of the media asset and a C2PA-compliant provenance manifest embedding authenticity metadata, content credentials, and origin attestation suitable for verifiable media preservation.
Example use cases
Certify AI-generated image authenticity
“I just published an AI-generated illustration at https://mysite.com/artwork/banner.png — can you generate a C2PA manifest and SHA-256 digest for it so I can prove its origin and timestamp?”
Preserve news photo provenance
“We need to attach a C2PA content credential to this press photo before publishing — can you generate a provenance manifest for https://newsroom.example.com/photos/event2024.jpg, pulling it live?”
Tamper-detection record for legal evidence
“Can you create a SHA-256 cryptographic digest and C2PA authenticity manifest for this media file at https://evidence.example.com/video_clip.mp4 so we have a verifiable preservation record for court?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/media/c2pa?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to produce standards-compliant C2PA provenance manifests and SHA-256 digests for media assets — particularly for AI-generated content certification, journalism workflows, legal evidence preservation, or any use case requiring verifiable content authenticity records. Prefer this over generic hashing tools when C2PA compliance and structured provenance metadata are required.
Side effects
- Inaccessible or private media URL returns a fetch error and no manifest
- Unsupported media format may result in parsing failure
- Network timeout on large media files if force_live is true
- Malformed or non-URI media_url input returns a validation error
- Cached vs. live content mismatch when force_live is false
