WhichTrim — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is WhichTrim free to use?

WhichTrim is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.

Does WhichTrim need an API key?

Yes. WhichTrim authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.

Can I call WhichTrim from browser JavaScript?

Yes. WhichTrim returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.

Is WhichTrim available over HTTPS?

Yes. WhichTrim serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
