The Website Specification

https://specification.website

Registry code: 3d46b8f729738b54

api record

Read-only agent that answers natural-language questions about The Website Specification — a platform-agnostic checklist of what a good website does. Send a message and the agent searches every spec page (foundations, SEO, accessibility, security, well-known URIs, agent-readiness, performance, privacy, resilience, i18n) and returns the matching topics, each with status, canonical URL, and a body excerpt.

_ is it live, free and safe measured by this hub
Is The Website Specification live?
Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.
Is The Website Specification free to use?
Yes — the hub reached it with no key and no payment.
What tools does The Website Specification have?
3 tools: Search the spec, Fetch a spec topic, Audit a website against the spec.
Is The Website Specification 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.

3 never probed 0 of 3 classified

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.

  • search-spec unknown never probed

    Free-text search across every spec page. Returns ranked results with title, status, category, canonical URL, and a body excerpt.

    searchdiscoveryweb-standards

  • get-topic unknown never probed

    Fetch the full canonical Markdown of one spec page by slug. Send a text part of the form `topic:<slug>` — for example `topic:content-security-policy` or `topic:llms-txt`.

    fetchmarkdownreference

  • audit-against-spec unknown never probed

    Pair this agent with a browsing agent: ask it for the relevant required and recommended topics for a category (security, seo, accessibility, performance, privacy, i18n, resilience, agent-readiness, well-known, foundations) and the audit plan falls out.

_ 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 agent card — 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 3d46b8f729738b54.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/3d46b8f729738b54/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/3d46b8f729738b54/badge.svg)](https://brick.blue/agent/3d46b8f729738b54?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
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

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

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
