How this service works

AgentProof publishes Agent Transaction Passport™ and provides machine-paid evidence, provenance receipts, source comparison and change monitoring for autonomous transactions.

Output

Returns a JSON object containing a boolean success flag, the tool name ('create_evidence_receipt'), a receipt object with a unique UUID identifier and a SHA-256 integrity hash of the submitted content, and the service name 'AgentProof'. This receipt serves as a cryptographic attestation that the submitted payload existed in a specific state at the time of the call.

Example use cases

Audit trail for autonomous purchase

“My agent just placed an order on my behalf — create an AgentProof evidence receipt for the order confirmation data so I have a cryptographic proof of exactly what was agreed to at the time of purchase.”

Certify AI-generated report content

“I need to lock in an integrity receipt for the market analysis report my agent produced before I send it to the client — generate an evidence receipt so there's a SHA-256 hash proving the content wasn't altered after it was created.”

Provenance record for data source used

“Before my agent makes this loan recommendation, create an evidence receipt capturing the credit data snapshot it's relying on so there's an auditable, tamper-evident record of the source information used in the decision.”

When to prefer

Choose this endpoint when an AI agent needs to create a point-in-time cryptographic attestation of transaction data, content, or a decision artifact — especially when auditability, tamper-evidence, or downstream trust verification is required. It is particularly suited to agentic workflows where a human or regulator may later need to verify what an autonomous system saw, decided, or transacted. Prefer this over simple logging when you need a machine-verifiable integrity hash rather than a mutable log entry.

Side effects

Missing or malformed payload body returns an error without creating a receipt
Payment failure (insufficient USDC or x402 protocol error) results in 402 response and no receipt created
Network timeout leaves receipt creation state unknown — UUID may or may not have been assigned
Duplicate submission of identical content produces a new UUID rather than deduplicating
Invalid content encoding may cause SHA-256 computation to fail or hash a differently-encoded version than expected
