Run a raw Overpass QL query against the Overspan hosted Overpass API (full-planet OpenStreetMap data, minutes behind live). Use this when the helper tools are too narrow. Always bound the query to an area and cap the output (for example: out center 25;). Start with [out:json]. Queries without [timeout:] get 25 seconds. Read the overspan://overpass-ql resource for syntax and the overspan://differences resource for how this server differs from the public ones.

Find OpenStreetMap features matching tag filters within a radius of a point. Returns up to 'limit' elements with their tags and a centre coordinate. Good first tool for questions like 'what cafes are near X'. For larger or unknown result sets, call count_features first.

Find OpenStreetMap features matching tag filters inside a bounding box (south, west, north, east in decimal degrees). Returns up to 'limit' elements with their tags and a centre coordinate. Keep boxes small; for city-sized areas call count_features first.

Count OpenStreetMap features matching tag filters in an area without returning them. Cheap. Use this before pulling data when the result size is unknown. Give either a point (lat, lon, radius_m) or a bounding box (south, west, north, east).

Check this API key's tier, its limits, month-to-date quota, and recent request history. Does not consume query quota. Use it to pace yourself when running many queries.
