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 an 'ok' boolean, the tool name 'compare_two_sources', a provenance receipt object with a UUID and SHA-256 integrity hash, and the service name 'AgentProof'. This receipt acts as machine-verifiable evidence that the comparison was performed.
Example use cases
Dual-source fact verification for agent decisions
“Before my agent acts on this news, compare https://reuters.com/article/xyz and https://apnews.com/article/xyz and give me a provenance receipt proving both sources agree on the key facts.”
Compliance audit trail for contract comparison
“I need to prove that two versions of this contract are identical — compare https://vault.example.com/contract-v1.pdf and https://vault.example.com/contract-v2.pdf and return a receipt with an integrity hash I can store for auditing.”
Change detection between published data feeds
“Check whether the pricing data at https://vendor-a.com/prices.json and https://vendor-b.com/prices.json match right now, and give me a timestamped AgentProof receipt documenting what you found.”
Technical details
Endpoint
POSThttps://agentproof.hatchable.site/api/paid/compare_two_sources?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs tamper-evident, machine-paid proof that two sources were compared — especially for compliance, audit trails, or trust verification in agentic pipelines. It is distinct from simple diff tools because it produces a cryptographic provenance receipt (UUID + SHA-256) suitable for downstream verification. Prefer it over generic comparison tools when the receipt itself (not just the result) is the artifact that matters.
Side effects
- Payment of 0.1 USDC not provided or rejected — 402 Payment Required returned
- One or both source URLs are unreachable or return errors — comparison cannot proceed
- Source content too large or unsupported format — processing failure
- Network timeout fetching one of the sources — partial failure with error response
- Malformed request body — 400 Bad Request with error detail
