Counters

48 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 8,525 endpoints in Inference 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: 3,710 in the category are counted higher and 4,814 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 48 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

Buffer a geometry by a distance in metres and get the offset polygon back. Use it for service areas, setbacks, and proximity envelopes you will later test with POST /v1/pip. Accepts any geometry -- point, line, polygon, or a collection of them, each buffered about its own centre latitude -- and answers with a Feature, or a FeatureCollection when you sent several. A buffer that collapses (a negative distance larger than the shape, or any negative distance on a point or a line) answers geojson:null with empty:true, which is an answer and not an error. Geodesic-aware: turf buffers in an azimuthal equidistant plane scaled by a sphere, which is a systematic -0.56% error at the equator running to +0.44% at 80 deg latitude, and this endpoint cancels that by scaling the distance to the Gaussian radius of curvature at the feature's own centre latitude. Measured against GeographicLib the result is then within +/-0.34% of the requested distance at the equator, +/-0.08% at 60 deg, +/-0.04% at 70 deg and +/-0.01% at 80 deg; the residual is the ellipsoid's north-south versus east-west curvature, which no single sphere can represent, and it shrinks towards the poles. Between vertices the polygon edge cuts a further 1 - cos(pi/(4*steps)) inside the true offset curve, 0.054% at the default steps=24. Input is EPSG:4326 only. Limits: 2000 positions across the whole document, 1 MiB request body, distance within +/-1000000 m, steps 1 to 128.
