It's a 3-digit code a server sends back with every HTTP response, telling the client whether the request succeeded, needs a redirect, or failed, and roughly why.
1xx is informational, 2xx means success, 3xx means redirection, 4xx means the client made a bad request, and 5xx means the server failed to fulfil a valid request.
The check is a direct request from your browser to the URL you enter. EaseDev Studios does not proxy, log, or store the URL or response anywhere except your own browser's local history.
Browsers enforce CORS. If the target site doesn't send permissive CORS headers, the browser blocks JavaScript from reading the real status code, even though the request went through.
401 Unauthorized means you're not authenticated yet. 403 Forbidden means you are identified but not allowed to access that resource.
No. Favorites and check history are stored only in your browser's local storage on this device and are never uploaded anywhere.
Yes. Use the Export buttons to download the entire reference as JSON or CSV for offline use or import into your own docs.
It means you've hit a rate limit — the server is telling you to slow down. Some servers include a Retry-After header indicating when to try again.
