geoprimitives
Get the extent of a geometry or a whole collection: a map viewport, a tile query window, a cheap prefilter before you pay for a containment test. Takes any geometry type, not just polygons. Bounding box of any geometry as [minLongitude, minLatitude, maxLongitude, maxLatitude]. Naive minimum and maximum per axis, so a geometry spanning the antimeridian reports a full-width longitude range rather than the narrow band it occupies; the response flags that case instead of guessing which side you meant. Input is EPSG:4326 only. Limits: 100000 positions across the whole document, 1 MiB request body.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 27 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service geoprimitives and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=geoprimitives' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://api.geoprimitives.dev/v1/geometry/bbox, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
