How this service works

HumanMirror — infrastructure de confiance, gouvernance, découverte et échange pour systèmes autonomes.

Output

Returns a cryptographic execution receipt containing a deterministic fingerprint, timestamp, and attestation of the tool call or input/output pair, enabling third parties to verify that a specific agent action occurred with specific data without being able to alter the record.

Example use cases

Audit trail for regulated AI workflows

“I need a cryptographic execution receipt for the AI decision my agent just made — it took a loan application as input and returned an approval score — so we have verifiable provenance for the compliance audit.”

Multi-agent handoff verification

“My orchestrator agent just passed a task result to a sub-agent; create an execution receipt for that handoff so the receiving agent can verify the output wasn't tampered with before acting on it.”

Debugging deterministic agent replay

“I want to prove that when my agent called the data enrichment tool with this exact input last Tuesday, it produced this specific output — can you generate a cryptographic receipt I can use to verify the execution later?”

Technical details

Endpoint

When to prefer

Choose this endpoint when you need tamper-evident, cryptographically verifiable proof that a specific AI-agent tool call or input/output pair occurred — particularly for compliance, auditing, multi-agent handoffs, or replay verification. Prefer this over simple logging when the integrity of the record itself must be independently verifiable and the record must be deterministic across identical inputs.

Side effects

Malformed or missing tool call payload causes 400 Bad Request
Payment failure or insufficient USDC balance returns 402 Payment Required
Non-deterministic or unstable input data may produce unreliable receipts
Receipt verification mismatch if payload was mutated between creation and verification
Timeout if the execution payload is excessively large
