api record

Sourced history. Every entry is a sentence quoted verbatim from a specific English Wikipedia revision and carries that revision id, so a claim built on it stays checkable. Years use astronomical numbering: -43 is 44 BCE. Reuse is free under CC BY-SA 4.0; cite the article and revision id.

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.

  • get_disagreements open 16h ago

    Where two sources slashyear checks against each other disagree: leaders' terms (Wikipedia lists vs Wikidata), birth and death dates (Wikipedia year articles vs Wikidata), Nobel Prizes (Nobel API vs Wikidata). Useful before trusting either source.

    Official data series by year from the agencies that publish them, each cross-checked against a second copy: U.S. unemployment, federal funds rate, GDP, population, federal debt, Mauna Loa CO2, global temperature anomaly, Fed exchange rates. Omit series to list them.

  • get_nobel_prizes open 16h ago

  • get_leaders open 12h ago

    Who led a country (or every country) in a year, 1800-2025: heads of state, heads of government and ruling-party leaders, in the order they held the post. Each name is quoted from Wikipedia's list of state leaders (revision id given) and kept only where the person's Wikidata record holds the same post over the same years, so a missing name means the sources disagree, not that the post was empty.

  • get_number_one_song open 12h ago

  • get_year reads open 12h ago

    Everything the record holds for one year: the headline summary and every dated entry, grouped by subject, each with its source revision.

    arguments 12 lines
  • get_country reads open 9h ago

    One country's dated record, century by century, harvested from the per-country year articles English Wikipedia writes separately ('1969 in Japan') and never indexes together. Use this when the question is about a nation rather than a year or a subject.

  • get_world_on_date open 9h ago

    The world on one date in a single answer: the dated entries for that exact day, births and deaths that day, every state's office holders that year, the Billboard Hot 100 No. 1 in force, U.S. prices and CPI, world population, official series (unemployment, rates, GDP, debt, CO2, temperature), Federal Reserve exchange rates for that day, and that year's Nobel Prizes. Each part carries its source; parts no source covers are absent.

  • search_history reads open 9h ago

    Full-text search across every dated entry in the historical record, plus the subjects that match. Each entry is a sentence quoted verbatim from a numbered English Wikipedia revision and carries that revision id, so an answer built on it can cite a source that will still say the same thing next year. Use this whenever you need a dated fact.

  • get_year_facts open 2h ago

    What a year (1800-2025) looked like in numbers, from outside sources rather than encyclopedia prose: world population, U.S. CPI and what a dollar then is worth now, average U.S. prices (gas, eggs, bread, milk, houses, income, minimum wage), who led the major powers, and the Billboard Hot 100 No. 1 songs. Every figure carries its source. For any other country's leaders use get_leaders.

  • get_timeline reads open 2h ago

  • check_claim unknown never probed

    Check one dated sentence against the record before stating it. Leaders, Billboard No. 1 singles and Nobel Prizes get a structured check that can return 'supported' or 'contradicted' with the source. Other claims are matched against the dated entries and the answer says where the record dates sentences holding the claim's key words (matched_same_year, matched_other_years, ...), with the entries as evidence.

_ 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 6b94741ebbc4bd54.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6b94741ebbc4bd54/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/6b94741ebbc4bd54/badge.svg)](https://brick.blue/agent/6b94741ebbc4bd54?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.
