api record

Edgepedia is a free encyclopedia for facts about people, places, events, and concepts: more than 400,000 articles with citations, by EdgeChat. Call `search` with a subject's name ("Mount Fuji"), not a question; a result's `text` often answers a simple fact. Call `fetch` with a result's id for the whole article, or with a `topic:` id for a topic's articles. Link each article you use; show its `credit` line with any text you quote. Corpus release metadata: {"corpus_version":"1.8.0","corpus_updated":"2026-10-21","release_notes":"https://www.edgechat.ai/edgepedia/updates#1.8.0"}. These fields…

_ is it live, free and safe measured by this hub
Is edgepedia live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is edgepedia free to use?
Yes — the hub reached it with no key and no payment.
What tools does edgepedia have?
5 tools: fetch, search, connect, related, resolve.
Is edgepedia 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.

what callers paid

inferred, not observed

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

_ what it can do 5 tools
5 never probed 0 of 5 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.

  • fetch reads unknown 6h ago

    Read an encyclopedia article in full: one Edgepedia article as Markdown with its citations, by a `search` result's id. Returns id, title, text, url, and metadata (topic path, license, credit). A `topic:` id lists that topic's parent, narrower topics, and articles, 120 a page; `topic:root` is the top of the tree, `topic:geo` the geography tree. `citations: false` gives [n] markers instead of inline source links. Show the `credit` line with any text you quote.

  • search reads unknown 6h ago

    Search an encyclopedia for facts about a person, place, thing, event, or concept: Edgepedia, more than 400,000 articles with citations. Pass the subject's name ("Mount Fuji", "photosynthesis"), not a question; other names and misspellings match, and when no title matches, articles whose text does follow, marked `match: fulltext`. Returns results with id, title, url, and preview text, plus a `topic:` result when the query names a topic ("painters"); pass an id to `fetch`. `limit` and `page` reach further results.

  • related unknown 19h ago

    Find encyclopedia articles related to an Edgepedia article: its topic-mates, a few from each neighboring topic, and its geography neighbors. Pass its id, as for `fetch`. Returns groups of results; `fetch` a group's `topic` id for more.

  • resolve unknown 19h ago

    Find which encyclopedia article a name means: Edgepedia's best match for a person, place, thing, or concept named in a text, with a confidence, whether the name is ambiguous, and the alternatives. Pass the name ("Mercury"), and optionally words from the text around it (`context`: "planet orbit") or a topic id the article must sit under (`type`). Returns `result` (id, title, url) and `alternatives`; pass an id to `fetch`.

_ try it over mcp 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 bb5fd13229338171.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/bb5fd13229338171/claim. Over MCP: the claim_endpoint tool.

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.

card completeness
90%

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.

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