The box is the middle half of the market, $0.0050 to $0.010; the whiskers reach the 10th and 90th percentiles and the axis between them is logarithmic. Listed prices only — what a service asks, not what it was paid.

Using Roundhouse, find x402 endpoints that can do what I need, tell me what each call costs, and whether the endpoint answered when last probed. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=<what-you-need>' Then check the merchant's real payment record before paying: curl -s 'https://api.roundhouseai.io/v0/merchants/<payTo-wallet>' Always read the price from the live 402, never from a cached figure. 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.
