matchwire.win — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is matchwire.win free to use?
matchwire.win 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 matchwire.win need an API key?
Yes. matchwire.win 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 matchwire.win from browser JavaScript?
Not directly. matchwire.win 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 matchwire.win available over HTTPS?
Yes. matchwire.win serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
