Before you pick one
IP location is approximate and can be wrong by a whole city. Use it to pick a default country or language, not to make a decision the user cannot override.
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.
