Accord Trace

Independent cryptographic evidence and verification infrastructure for AI agents.

Skills

• 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 integrity verification later. The service records a service timestamp but does not establish truth or legal validity.

• 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.
