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 an 'ok' boolean, the tool name 'detect_page_change', a receipt object containing a UUID and a SHA-256 integrity hash of the page content, and the service name 'AgentProof'. This receipt acts as machine-verifiable proof of the page's state at the time of the call.

Example use cases

Regulatory page change monitoring

“Monitor https://sec.gov/rules/final.shtml and tell me if it's changed since yesterday — I need a provenance receipt with an integrity hash I can use as auditable evidence.”

Autonomous contract source verification

“Before my agent signs this smart contract, check if the source page at https://defi-protocol.io/contract-terms has been modified and return a signed receipt proving what it said at time of check.”

Competitive pricing page surveillance

“Check if the pricing page at https://competitor.com/pricing has changed since my last check and give me a tamper-evident receipt with the SHA-256 hash of the current content.”

When to prefer

Choose this endpoint when an autonomous agent needs cryptographically verifiable, receipted proof that a web page has or has not changed — especially in compliance, audit, legal, or trust-sensitive workflows where a simple diff is insufficient and a signed provenance record is required. It is preferable over generic web scraping or diffing tools when the output must serve as machine-paid evidence in an autonomous transaction context.

Side effects

URL unreachable or returns non-200 status — ok:false with error detail
Invalid or malformed URL input — request rejected before fetch
Page content too large to hash within limits — may timeout or error
Payment not processed — x402 payment required before response
Transient network error fetching target page — retry recommended
