Shares a payout wallet with 20 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Validate GeoJSON against RFC 7946 and get back a structured list of problems, not a bare boolean. Checks structure, coordinate range, ring closure, ring winding order, consecutive duplicate vertices, self-intersections, and hole nesting. Every issue carries the feature, geometry, ring and position index it sits on, so a 500-feature collection is actionable rather than merely condemned. Reach for it before paying for an operation on data you did not author, and to find out why /v1/geometry, /v1/h3/polyfill or /v1/pip refused a document: those endpoints reject unclosed rings and out-of-range coordinates rather than guessing. Errors make a document invalid; warnings -- duplicate vertices, the crs member RFC 7946 removed -- do not, and are reported separately. One price per call whatever the document: a single Point costs exactly what a 1 MiB FeatureCollection costs, so send the whole collection rather than a document at a time. That is measured rather than assumed -- a Point is about 0.0015 ms of compute on this runtime and a 1 MiB collection about 10 ms, a spread far below what it costs to settle one payment -- which is why there is no size tier here to choose between and no bulk sibling to look for. Nothing is modified here: POST /v1/geojson/repair is the endpoint that rewrites. Limits: 1 MiB request body, and a self-intersection budget of 2000000 segment-pair comparisons per request, enough for any ring under about 1400 vertices. Rings past the budget are listed in checksSkipped with the reason, never silently passed as clean.
