How this service works

OpenStreetMap building footprints via Overpass — give a coordinate (or bounding box) and get building geometry as GeoJSON, footprint area (m²), levels and height by coordinate. Worldwide coverage, OpenStreetMap data.

Output

GeoJSON feature(s) for the matching building(s) including polygon geometry, computed footprint area in square metres, number of levels/floors, and estimated height — sourced from OpenStreetMap via Overpass, with worldwide coverage.

Example use cases

Example prompt

“What does the building footprint look like at the Eiffel Tower — coordinates 48.8584, 2.2945? I need its GeoJSON outline, floor count, height, and footprint area in square meters, with a search radius of 100 metres.”

Technical details

Endpoint

GEThttps://x402-endpoints.onrender.com/osm/building-footprint?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need building geometry, footprint area, floor count, or height for any location worldwide using OpenStreetMap data. Ideal for urban analysis, real estate enrichment, solar potential preprocessing, navigation, or any geospatial workflow needing building polygons. Prefer over proprietary datasets when open data and global coverage matter more than cadastral precision.

Side effects

No building found at the given coordinate or within the radius — returns empty feature collection
Bounding box exceeds ~2km span limit — returns error
Invalid lat/lon values outside valid range — returns 400 error
Overpass API temporarily overloaded or unavailable — returns 503 or timeout
Missing required lat/lon or bbox parameter — returns 422 validation error
