Counters

28 observations, 1 of them a change, fewer than the 3 a trace needs

How big is this endpoint among the ones like it?

Calls counted in the trailing thirty days across the 1,632 endpoints in Search that carry counters, binned on a logarithmic scale because the range runs over five orders of magnitude. The marked bin is this endpoint, at 1: 980 in the category are counted higher and 651 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 28 observations, and 3 changes are the fewest this site will draw a trace through, because two points and a guess are not a series. Every observation is in the JSON.

What the listing says

Index points to H3 cells. 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. Limits: 10000 points, 4 resolutions per call, and a 1 MiB request body.
