geoprimitives
Answer which of your points fall inside which of your polygons, in one call. Use it to tag events with the district, catchment or territory they belong to, to filter a point set down to a study area, or to join two datasets that share nothing but geography. The answer comes back twice, as a dense 0/1 matrix and as a per-point list of polygon indices, so neither shape needs rebuilding on your side, and polygon ids are echoed as column labels so the matrix joins straight back to your records. Rings must be closed and coordinates must be EPSG:4326: run POST /v1/geojson/repair first if they are not, and POST /v1/transform if they are not in degrees. Costs scale with polygon detail, not just polygon count, so POST /v1/geometry/simplify on the polygons is often the cheapest way under the caps. The matrix is dense: every point is tested against every polygon, one row per point and one column per polygon, 1 for inside and 0 for outside. A point exactly on an edge or vertex counts as inside unless "ignoreBoundary" is set. Two caps, both on products rather than on either side: at most 250000 point-polygon pairs, and at most 25000000 point-vertex tests, since a ray cast walks every edge. Input is EPSG:4326, longitude then latitude. Limits: 250000 points, 2000 polygons, 100000 polygon positions, and a 1 MiB request body.

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.

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/pip, 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.
