Safe API request testing

Build HTTP requests in the browser, inspect responses, and export cURL commands for reproducible API debugging.

Reproduce requests

Combine method, URL, headers, and body in one screen to reproduce an issue and inspect the status code.

Share as cURL

Export a browser-built request as cURL so backend, QA, or operations teammates can reproduce it.

CORS still applies

Requests are sent from the browser, so the target API CORS policy can affect whether the request succeeds.

Real input and output

Turning a request into cURL

Input

GET https://api.example.com/users?limit=10
Authorization: Bearer <token>

Output

curl 'https://api.example.com/users?limit=10' \
  -H 'Authorization: Bearer <token>'

A single cURL line is the most reliable way to hand a repro to a teammate.

Errors you will hit

CORS errors

The request goes out from the browser, so you cannot read the response unless the target server allows CORS. It is a browser policy rather than a server fault — the same request succeeds from cURL in a terminal.

Before you paste anything sensitive

This tool sends a real request to the address you enter. Swap production tokens and personal data for test values, and mask headers before sharing results.

Things to check

Protect sensitive values

Replace production tokens, personal data, and internal API addresses with sample values before sharing.

Browser policy differs

A healthy server can still be blocked by CORS, auth-cookie rules, or mixed content policy. Browser results can differ from server-to-server calls.
