About
Photon is an open-source search engine for the world's map. Type a city, street, or landmark and it returns coordinates, and it also works in reverse. Coordinates in, nearest places out. A public server is free to use with no key; if you get busy, you can host your own copy.
Details
No key needed. You can call it right away.
Auth: No key
Rate limit: No key and no fixed numeric limit, but it is a community service. Be polite and self-host for heavy use.
