Micro User Service — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Micro User Service free to use?
Micro User Service 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 Micro User Service need an API key?
Yes. Micro User Service 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 Micro User Service from browser JavaScript?
Yes. Micro User Service 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 Micro User Service still working?
Not at our last check on 2026-09-18. Micro User Service did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is Micro User Service available over HTTPS?
Yes. Micro User Service serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
