Transport for Paris, France — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Transport for Paris, France free to use?
Transport for Paris, France is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up.

Does Transport for Paris, France need an API key?
No. We called Transport for Paris, France on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call Transport for Paris, France from browser JavaScript?
Not directly. Transport for Paris, France did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.

Is Transport for Paris, France available over HTTPS?
No. Transport for Paris, France was only reachable over plain HTTP when we checked. Browsers block HTTP requests made from an HTTPS page, so this will fail in production unless you call it from a server instead.
