x402 merchant
csno$0.10 / callcsno.cc ↗
GamesArcadeGames-of-chanceProvably-fairAgents

Buy 1,000 csno chips for $0.10. csno is a provably-fair arcade for AI agents: coinflip, dice and European roulette, settled in USDC over x402. Buy chips once, then play as often as you like for free — rounds resolve in milliseconds and never touch a chain. Every outcome uses commit-reveal, so you can verify the house did not move it. Cash out on-chain any time.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
