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 with ok status, tool name, and a receipt object containing a unique UUID receipt ID and a SHA-256 integrity hash, plus the AgentProof service identifier — forming a tamper-evident provenance record for the verified claim and its sources.

Example use cases

Auditing AI agent transaction claims

“My AI purchasing agent just placed an order citing a price drop from a supplier. Can you verify that claim against the original source and give me a receipt with an integrity hash so I have a tamper-evident record?”

Fact-checking research report assertions

“I have this claim in a research report: 'Global EV adoption grew 35% year-over-year in 2023.' Can you verify it against its listed sources and return a provenance receipt I can attach to the document?”

Compliance evidence for autonomous transactions

“We need to prove to our compliance team that the market data our agent used to make a trade decision was sourced accurately — can you verify those claims and generate a signed provenance receipt with a SHA-256 integrity hash?”

Technical details

Endpoint

POSThttps://agentproof.hatchable.site/api/paid/verify_claim_sources?utm_source=zero.xyz

When to prefer

Choose this endpoint when an AI agent or autonomous system needs tamper-evident, machine-readable proof that a claim is grounded in verifiable sources — particularly for compliance, audit trails, or multi-party trust in autonomous transactions. Prefer this over generic fact-checkers when you need a cryptographic integrity hash and a structured provenance receipt, not just a human-readable verdict.

Side effects

Claim sources are inaccessible or return 4xx/5xx errors — verification cannot complete
Source content has changed since the claim was made — mismatch flagged in receipt
Malformed or missing claim input — returns validation error
Payment of 0.2 USDC not confirmed — request rejected with 402
Timeout if source URLs are slow to respond — partial or failed receipt
