Send \"points\" as [longitude, latitude] positions in EPSG:4326 and get each one's containing H3 cell at one or several resolutions, optionally with the cell's centre and its closed boundary ring. Use it to bucket points into a fixed hexagonal grid so datasets that share no keys can be joined, aggregated or deduplicated on cell id. This route indexes positions and nothing else. It does not accept polygons: a body carrying \"geojson\" is refused rather than served, and because \"points\" is required here that refusal costs you nothing -- it happens before a price is quoted. To cover a Polygon or MultiPolygon with the cells that tile it, POST /v1/h3/polyfill instead. That is a separate route at a higher price because it is a materially more expensive job: measured on this runtime, indexing one point takes about 0.003 ms and returns 168 bytes, while the cheapest possible polyfill takes about 1.5 ms -- the cell count has to be estimated before any cell is generated -- and a polyfill at its cell cap is about 200 ms and 1.8 MB. This route is priced with POST /v1/transform, which does the same class of per-position work, and below POST /v1/h3/polyfill. Every call needs exactly one of \"resolution\" or \"resolutions\". Input is EPSG:4326, longitude then latitude; out-of-range values are refused rather than normalised, because H3 will happily index a latitude of 950 and answer with a real, wrong cell.
