Description
AttestPage is a tool designed to provide AI agents with signed evidence about web pages. It allows users to verify whether a quote appears on a page, check every citation in an answer, or fetch a page to learn what actually came back. The tool supports checking a list of links, verifying package names on npm, PyPI, or crates.io, and timestamping a hash. Each answer carries an Ed25519-signed receipt that can be checked offline against published keys.

The platform offers several endpoints, each with specific functionalities. For instance, the POST /v1/verify/quote route checks your exact words against a page for US$0.01 per call. The POST /v1/verify/citations route allows checking up to 10 quote and URL pairs for US$0.10 per batch. Other routes include verifying a document, fetching a page, rechecking a page for changes, checking links, and verifying packages.
Payments are handled via the x402 protocol, with transactions settled in USDC on the Base mainnet. There is no free trial, but free samples are available to demonstrate the tool's capabilities. The tool is particularly useful for AI agents needing to verify the authenticity and accuracy of web content, ensuring that the data they rely on is trustworthy.
AttestPage is ideal for developers and organizations that require reliable verification of web content, providing a robust solution for maintaining data integrity in AI applications.
