api record

Polemia (https://polemia.ai) is a free live quiz game played on phones: one person hosts, everyone else joins with a short code, no sign-up. Use create_quiz when the user wants a new quiz on a topic for a class, party, team or pub quiz; give them BOTH links it returns (host_url for whoever runs the game, join_url or the code for the players). Use find_quizzes first when a ready-made quiz would do. Use daily_question for Polemia's one question of the day for the whole world.

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.

  • daily_question open 2h ago

    Today's Polemia question: one opinion question a day, answered anonymously by people all over the world. Free. Use it when the user wants a question of the day, a conversation starter, or to see what the world thinks. Returns the question, its answer options and answer_url, where the user votes and then sees everyone's results.

  • create_quiz unknown never probed

    Make a new live multiple-choice quiz on Polemia about any topic, ready to play on phones with a join code. Use it when the user wants a quiz, trivia game or icebreaker for a class, party, family, team or pub quiz. Takes 10 to 60 seconds. Returns join_url and code (for the players), host_url (for the person running the game: opening it makes that browser the host, and it works once), qr_url (a QR code image of the join link) and an instructions sentence to pass on. Always give the user both host_url and join_url. "facts" quizzes have right answers; "opinions" quizzes are scored by what the majority picks. Topics that target people, politics, war or adult material are refused.

  • find_quizzes unknown 2h ago

    Search Polemia's free public library of ready-made quizzes. Instant and free. Use it when the user wants a quiz on a common topic and does not need a new one written. Returns up to 10 quizzes, each with a title, question count, kind, language and play_url (the quiz's page, where the user starts a live game with it).

_ 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 203175c07fba326c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/203175c07fba326c/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/203175c07fba326c/badge.svg)](https://brick.blue/agent/203175c07fba326c?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
70%

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.
