FitKit Nutrition API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is FitKit Nutrition API free to use?
FitKit Nutrition API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does FitKit Nutrition API need an API key?
FitKit Nutrition API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call FitKit Nutrition API from browser JavaScript?
Not directly. FitKit Nutrition API 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 FitKit Nutrition API available over HTTPS?
