Repair GeoJSON and get the fixed document back with a log of every alteration: rings rewound to RFC 7946 winding order, consecutive duplicate vertices dropped, unclosed rings closed, and polygon nesting fixed (mis-ordered exterior rings, holes that fall outside their exterior, MultiPolygon members that are really holes). Reach for it when POST /v1/geojson/validate reported errors, or when /v1/geometry, /v1/h3/polyfill or /v1/pip refused your document -- unclosed rings are the usual reason, and this is the cheapest way to clear them. Conservative by design: it only rewrites the classes above, and anything else it found is returned in unrepaired rather than guessed at, so it will not invent geometry or move a coordinate. Idempotent -- a conformant document comes back untouched with changed:false, so a second call costs money and changes nothing. Your input object is never mutated. Coordinate values are preserved exactly; nothing is rounded or reprojected. Limit: 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.

GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 26 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/geojson/repair, 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.
