How this service works
invinoveritas /prove — a signed, independently-verifiable attestation of a prior execution that anyone recomputes offline to confirm it is untampered. The
Output
Returns a proof object containing the invinoveritas.proof.v1 schema identifier, the original action_id, and a signature_type field indicating either 'nostr' or 'hmac'. Status field confirms success. If nostr_publish was true, the proof is also broadcast as a Nostr event.
Example use cases
Example prompt
“Generate a cryptographic proof for my agent execution with action_id 'exec_abc123' and publish it to Nostr so there's a verifiable on-chain record of what happened.”
Technical details
Endpoint
POSThttps://api.babyblueviper.com/prove?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to produce a cryptographically verifiable, auditable attestation that a specific action was executed — especially in trustless or multi-agent coordination contexts where proof of execution must be shared on Nostr or verified by other parties. Prefer over generic logging when a tamper-evident, signed record is required.
Side effects
- Invalid or unknown action_id returns an error — the action must exist in the system before it can be proved
- Payment failure via Lightning/L402/x402 results in 402 response before proof is generated
- Nostr publish failure may succeed locally but fail to broadcast the Nostr event
- Expired or already-proved action_id may return a conflict or not-found error
