api record

Signed evidence about web pages from https://vehcdj664efetfrsolne5umanq.srv.us: check a quote is on a page before citing it, check every quote and link in a finished document, fetch a page with a verdict on what came back (real page, bot wall, paywall, error), check links, check package names before installing them, or timestamp a SHA-256. Each answer has a "receipt" (an Ed25519-signed JWS); check one with attestpage_verify_receipt (free). A receipt records what the fetcher saw at a given time; it does not show that a statement is correct.

_ is it live, free and safe measured by this hub
Is attestpage live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is attestpage free to use?
Yes — the hub reached it with no key and no payment.
What tools does attestpage have?
10 tools: attestpage_preview_document, attestpage_verify_quote, attestpage_verify_citations, attestpage_fetch, attestpage_check_links, attestpage_check_packages, attestpage_attest, attestpage_verify_document, ….
Is attestpage safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • attestpage_preview_document unknown 1h ago

    Use before paying for POST /v1/verify/document: send the same body, and get back the quote and link pairs it would check, what was skipped and why, the number of parts and the exact price. Nothing is fetched, signed or charged. Free. Free. Docs: https://vehcdj664efetfrsolne5umanq.srv.us/docs/verify-document

  • attestpage_verify_quote unknown never probed

    Use when an agent is about to quote or cite a web page: send the URL and the quote in your exact words, and get back whether those words, or a close fuzzy match, are on the live page (exact, fuzzy or none), with offsets, context, page hashes and a signed receipt, all in one call, so a misquoted or made-up quote is caught before a user sees it. For a paraphrased claim, match "passages" returns the 3 passages sharing most of its words, scored, with offsets: evidence to judge, not a verdict (no LLM, same answer every call). PDFs are read too, on the full service (an edge server answers 501 not_on_edge, uncharged): a match or passage on a PDF also gives pdf_page and pdf_page_end, its 1-based pages. For 9 or more quotes on one page, verify/quotes costs less: one call checks up to 20. Costs US$0.01 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid. Pay by putting an x402 payment payload in _meta["x402/payment"]. Without one it uses the free trial (5 calls a day per address), then returns the payment requirements.

  • attestpage_verify_citations unknown never probed

    Use before giving a user an answer that cites web pages: send up to 10 quote and URL pairs, and get back for each one an exact, fuzzy or none match, score, offsets, context and the page's status, final URL and content_kind, under one signed receipt. Each page is fetched once. With match "passages", each paraphrased claim gets its 3 best-sharing passages, scored, as evidence to judge, not a verdict. A URL whose domain does not resolve is reported (http_error) and the batch is charged; a batch where no URL resolves gets 422 and is not charged. A cited PDF is read too, on the full service: each match or passage on it also gives pdf_page and pdf_page_end, its 1-based pages. A cited paper with a DOI also gets Crossref's title, authors, year and journal and a retracted flag (Retraction Watch data). For 1 to 9 pairs, one verify/quote call per pair costs less, without the Crossref data. Costs US$0.10 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid. Pay by putting an x402 payment payload in _meta["x402/payment"]. Without one it uses the free trial (5 calls a day per address), then returns the payment requirements.

  • attestpage_fetch unknown never probed

    Use when an agent needs a web page as clean text and must know what actually came back: send a URL, and get back a content_kind verdict (real, bot_wall, js_shell, paywall, http_error and others), status, final URL, title, hashes, prompt-injection flags, the clean text when return_text is set, and a signed receipt, so a bot wall, JavaScript-only shell, paywall or error page is not summarised as the real page. PDFs are read too, on the full service (an edge server answers 501 not_on_edge, uncharged): the text layer, pages separated by a form feed, and page.pdf with page_count, pages_read and truncated. Costs US$0.002 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid. Pay by putting an x402 payment payload in _meta["x402/payment"]. Without one it uses the free trial (5 calls a day per address), then returns the payment requirements.

  • attestpage_check_links unknown never probed

    Use when an agent is about to give a user links or citations: send up to 10 URLs, and get back for each one the status, redirect chain, final URL, content_kind, title and hash, so a dead, moved or blocked link is caught before it is shown. A URL whose domain does not resolve is reported as dead (http_error, signal outcome_dns_error) and the batch is charged; a batch where no URL resolves gets 422 and is not charged. A live PDF link is reported as content_kind pdf (not read, so no title or hash); a PDF or other file with an error status is http_error. A link redirected to another site that answers 4xx/5xx is off_site with off_site_error: true. Costs US$0.005 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid.

  • attestpage_check_packages unknown never probed

    Use when an agent is about to install or recommend a package an LLM suggested: send up to 10 names, each with its registry (npm, pypi or crates), and get back whether the registry lists each name (exists true/false), latest version, description, licence, links, creation time and flags (deprecated, yanked, created_recently, name_differs), under one signed receipt, so a made-up package name is caught before install. It says whether the registry lists the name; it is not a security verdict. A batch where every lookup fails gets 502 and is not charged. Costs US$0.005 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid.

  • attestpage_verify_document unknown never probed

    Use before sending a finished answer or report that quotes web pages: send the document as written, and get back every quote with its link, found by fixed rules and checked on the live page: exact, fuzzy or none, score, offsets in your document and on the page, and each page's status, final URL and content_kind, under one signed receipt. Up to 10 quote and link pairs per call; a longer document is checked in parts, and the free preview (POST /v1/verify/document/preview) lists the pairs and the price first. With match "passages", each sentence that carries a link is a claim and gets its best-matching passages as evidence. For a part of 1 to 9 pairs, one verify/quote call per pair costs less; the free preview lists each pair and its part.

  • attestpage_verify_quotes unknown never probed

    Use when an agent is about to quote one web page several times: send the URL and up to 20 quotes in your exact words, and get back for each one whether it, or a close fuzzy match, is on the live page (exact, fuzzy or none), with offsets and context, plus the page's verdict and hashes, under one signed receipt. The page is fetched once and the call has one price for 1 to 20 quotes, so from 9 quotes up it costs less than one verify/quote call per quote. With match "passages", each paraphrased claim gets the 3 passages sharing most of its words, scored, as evidence to judge, not a verdict. Full service only (an edge server answers 501 not_on_edge, uncharged). A PDF is read too: each match or passage on it also gives pdf_page and pdf_page_end, its 1-based pages. Costs US$0.08 per call in USDC via x402 (Base Sepolia, a test network), charged only when the call succeeds; a bad request is refused unpaid. Pay by putting an x402 payment payload in _meta["x402/payment"]. Without one it uses the free trial (5 calls a day per address), then returns the payment requirements.

  • attestpage_verify_receipt unknown 1h ago

    Use when you are handed an AttestPage evidence receipt and need to check it before relying on it: verifies the compact JWS against this service's published keys and returns its payload, so a forged or altered receipt is caught.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id d741798df754acb0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d741798df754acb0/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/d741798df754acb0/badge.svg)](https://brick.blue/agent/d741798df754acb0?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
