Before you pick one

Public geocoders are shared community servers. Cache results, send at most one request per second, and never run a bulk job against them.

Open an API’s page to see the exact request we send, the answer it gave, and how many of the last 30 days it was up. If it is marked CORS you can run the request from the page itself.
