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
A JSON object containing 'ok' (boolean success), 'tool' name ('extract_page_facts'), a 'receipt' object with a unique UUID and a SHA-256 integrity hash of the extracted content, and a 'service' label ('AgentProof'). The receipt serves as a cryptographic provenance artifact proving what the page contained at extraction time.
Example use cases
Auditable evidence for agent purchase decision
“Before my agent buys this product, extract the facts from https://shop.example.com/item/123 and get me a verifiable receipt proving what the listing said at the time of purchase.”
Compliance snapshot of regulatory page
“Extract the key facts from https://regulator.gov/notices/2024-07 and generate a provenance receipt with an integrity hash so I have a tamper-proof record for our compliance file.”
Source attestation for research summary
“Grab the main claims from https://research.org/report/ai-safety and give me a receipt I can attach to prove exactly what the source said when my agent read it.”
Technical details
Endpoint
POSThttps://agentproof.hatchable.site/api/paid/extract_page_facts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs not just extracted facts but a cryptographically verifiable provenance record proving what a web page said at a specific moment — especially for AI-to-AI transactions, compliance audits, purchase decisions, or any scenario where disputed page content could arise. Prefer it over plain scrapers when the integrity and auditability of the source data matters as much as the data itself.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with error
- Page content is dynamic/JS-rendered and cannot be captured server-side
- Payment of $0.05 USDC not confirmed via x402 — request rejected
- Rate limiting or quota exceeded — returns error response
- SHA-256 hash cannot be computed if page returns binary/non-text content
- Receipt UUID collision or storage failure — rare but possible
