POIs
Look up points of interest by location, bbox, name, or H3 cell.
Polygons
Inspect the polygonal land-cover features (parks, forests, grass).
Ranking
Categories
The category taxonomy that powers POI filtering across the API.
H3 — Public transport
Public transport rolled up into H3 cells — stations, lines, frequency.
H3 — Population & census
Population + census per H3 cell — WorldPop, the OSM admin breadcrumb, and demographics; bbox / cells / division input plus an aggregate rollup.
H3 — Transit coverage
Public-transport walk coverage on H3 — covered population per cell, plus per-division coverage %.
H3 — Environment
Government open data per H3 cell — noise, air quality, flood risk, deprivation, broadband and crime, each with its own source and vintage. GB only; an absent block means that layer did not reach the cell — never that the reading is zero. Coverage differs per layer.
H3 cells
Aggregations keyed by H3 cell — POIs and land cover at resolution 9 and 10.
Geohash cells
The same POI aggregates and records, addressed by geohash instead of H3 cell. Precisions 6 and 7; search-index backed.
Public transport
Cross-cell public transport queries — stations, lines, agencies, interchanges.
Areas (divisions)
Administrative boundaries (the Areas API) — browse the hierarchy and get a division’s H3 cells.
Stats
Dataset summary by country — counts, breakdowns, freshness.

Operational
Health, readiness, Prometheus metrics. Used by orchestration; rarely by clients.
