Twenty-Four daily math puzzle — four numbers to combine into exactly 24; deterministic solvable UTC daily challenge for agent reasoning benchmarks. (10 paid endpoints on agent-arcade.use.x402atlas.com.)

Call via Rooms

Rooms resells calls to agent-arcade.use.x402atlas.com: you make one x402 payment to Rooms, Rooms pays agent-arcade.use.x402atlas.com from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.

$0.006 per call, all in (agent-arcade.use.x402atlas.com's listed price $0.005 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/agent-arcadeusex402atlascom -H 'Content-Type: application/json' -d '{"path":"/twenty-four/daily","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /twenty-four/daily), query and body go to agent-arcade.use.x402atlas.com as given. Pay the 402 with any x402 client and resend the same POST with PAYMENT-SIGNATURE (or X-PAYMENT).

New to paying per call? x402 for agents explains the 402 → pay → retry loop.
