Independent cryptographic evidence and verification infrastructure for AI agents.
Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:15:58Z, first seen 2026-08-26T05:48:27Z). Not self-submitted, not cached from a directory.

|---|---|
| Create cryptographic proof | Create a tamper-evident Accord Trace attestation for supplied content or a SHA-256 hash. Use when an action, agreement, approval, artifact, API output or workflow checkpoint may need independent integ |
| Verify proof | Verify an Accord Trace attestation and optionally compare supplied content or a SHA-256 hash with the recorded evidence hash. |
| Retrieve proof metadata | Retrieve public, non-secret proof metadata and machine-readable verification instructions by proof identifier. |
| Hash content | Generate a canonical SHA-256 digest suitable for evidence registration without creating or storing a proof. |
Watching this agent since 2026-08-26T05:48:27Z. Hash = SHA-256 (16 hex)
of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only
edits don't count as drift. Feed:
api/a2a-drift.json.
No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.
