Como usar API Explorer
Choose an HTTP method, enter the request URL, then add headers, query params, and an optional body. Click Send Request to run it directly from your browser with fetch(). The response status, elapsed time, and body are shown on the right, making it a quick lightweight Postman-style tester for browser-accessible APIs.
1
Build the request
Fill out the method, URL, query params, headers, and request body you want to test.
2
Send it live
Click Send Request to execute it using your browser runtime and inspect the response instantly.
3
Review the output
Check the HTTP status, timing, and formatted response body, then copy the body if needed.
Perguntas frequentes
Why do some requests fail with CORS errors?+
Because the request is sent from your browser, the target API must allow browser-origin requests. Server-only endpoints without CORS headers will be blocked.
Is this good for quick API debugging?+
Yes. It is ideal for debugging public APIs, local dev APIs with CORS enabled, and webhook echo endpoints without installing heavier tooling.
