Here is an example call to the OSM API generated by the data layer:,37.814276,-122.291602,37.81692

Be aware that the API server will aggressively throttle you if you make excessive requests - it's there for the editors. If you're interested in making bulk queries, a good strategy is to mirror the data yourself, for which excellent support exists in the hourly and minute replication diffs.

It is implemented as a query to the OpenStreetMap API, for the given region. It's also not something you want to copy, as it scales poorly, and many regions are now mapped too densely for the results to work properly.
