API Request Builder
Build and send HTTP requests from your browser. Requests are proxied through a Cloudflare Worker to avoid CORS restrictions.
Requests proxied to bypass browser CORS restrictions; your input is not stored.
Common Use Cases
- Test a protected API endpointSet the Authorization header with a Bearer token, choose POST, add a JSON body, and fire the request to test a protected REST endpoint without installing curl or Postman.
- Debug a webhookReplay a webhook payload to your staging endpoint by setting the correct Content-Type and signature headers, then inspect the full response.
- Verify an API's response schemaSend a GET request and inspect the response headers and body to confirm the content type, status code, and data shape before writing client code.
