OSM / Overpass
OpenStreetMap is the collaboratively edited map of the world; the Overpass API provides read-only structured queries over its data, and full history dumps preserve the map's past states. Overpass is keyless (with polite-use limits), and our search can query it directly. Relevant when you need to know what mapped features exist at a location, or to dig into the map's edit history.
