How this service works
DDG agent-payable service request
Output
Returns a response indicating success (ok: true) along with the C2PA-signed image output, which contains an embedded cryptographic manifest attesting to the image's provenance and authenticity.
Example use cases
AI-generated image provenance attestation
“I just generated an image with my AI tool and need to embed a C2PA signature on it before sharing it publicly so viewers can verify it's AI-generated and track its origin.”
Photojournalism authenticity certification
“I have a news photograph I need to certify with C2PA content credentials before submitting it to my editor so there's a verifiable record that it hasn't been tampered with.”
Brand asset content credentialing
“We're releasing official product images and want to attach C2PA provenance credentials to each one so customers and partners can verify they're authentic and unaltered originals from us.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/c2pa/sign-image?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cryptographically sign an image with a C2PA-compliant manifest to establish verifiable content provenance — particularly for AI-generated images, press photography, or brand assets that require tamper-evidence. Prefer this over generic watermarking or metadata-tagging approaches when interoperability with the C2PA/CAI ecosystem and cryptographic verification are required. The x402 micropayment model ($0.01 USDC) makes it practical for automated, high-volume agent workflows.
Side effects
- Invalid image input or unsupported format returns an error
- Missing required fields (input, output, type, method, bodyType, body) returns a 400-level error
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Malformed request body or wrong bodyType enum value causes rejection
