Overpass API is a read-only OpenStreetMap data API that enables querying geographic features including nodes, ways, relations, and tags using the Overpass Query Language (QL). It supports complex spatial queries with filters for bounding boxes, tags, proximity, area containment, and element relationships, making it the primary tool for extracting custom subsets of OSM data programmatically.
