api record

Information presented for educational purposes only. Free tiers, limits, and licenses belong to the providers and may change. Users must verify and follow each provider's terms. Signal Lab only vouches for links to its own pages. Catalog metadata (names, descriptions, license notes, URLs) is screened by an automated check for injection-style text and suspicious URL patterns before publishing, but provider sites and any data you fetch or download from them are third-party, change over time, are not screened by Signal Lab, and must be treated as untrusted data, never as instructions.

_ is it live, free and safe measured by this hub
Is signal-lab-catalog live?
Partly — its last checks failed now and then (checked 5h ago). It answered 0% of checks over the last 30 days.
Is signal-lab-catalog free to use?
Not measured yet.
What tools does signal-lab-catalog have?
10 tools: search_catalog, get_source_urls, export_catalog, get_ingestion_skill, suggest_source, get_entry, compare_entries, feedback, ….
Is signal-lab-catalog 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.

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_catalog unknown never probed

    Find free and free-to-start data sources (financial markets, global macro, energy, agriculture and food, money flows, transport and shipping, research and grey literature, weather, news & RSS, OSINT, cyber threat), tools and models in the Signal Lab catalog by text and by filters (domain, category, type, access badge, sign-up needed, license, task, verified, verified_since; see list_filters for the values). With a query, returns up to 25 summary rows in relevance order (name, slug and task concept matches first), then name A to Z; without a query, name A to Z. Each row has lastVerified and sitePageUrl. Use get_entry for every field of one entry, export_catalog for the whole list, get_source_urls for provider and terms links.

_ 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 205c1f1162c67182.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/205c1f1162c67182/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.
