API Tester

Send HTTP requests and inspect responses directly in your browser — no extensions required.

Browser CORS restrictions apply. Many public APIs block cross-origin requests. If a request fails unexpectedly, the server may not allow requests from browser pages. Use a proxy or server-side client for those APIs.

Request

Configure the endpoint, method, headers, and body.

Usage tips

Press Enter in the URL field to send quickly.

Set Authorization: Bearer <token> in the headers tab to authenticate requests.

Paste a JSON body in the Body tab for POST, PUT, and PATCH requests — the response will be pretty-printed automatically if it is valid JSON.
