HTTP Request Builder
Send live API requests and generate curl, fetch, axios snippets.
Requests go straight from your browser first. If the API blocks cross-origin calls, the request is retried through our fetch relay so you still get the response — avoid sending private credentials to APIs that need the relay.

Capture real responses from any site with API Inspector
Our free browser extension lists every API request a page makes — JSON, XML, CSV, HTML and media — and opens each one in the right Coders Hub tool with a single click.
About the HTTP Request Builder
Build an HTTP request with method, URL, headers and body, then send it directly from your browser and inspect the status code, timing, response headers and pretty-printed body. The same request is also exported as ready-to-run curl, fetch, axios, Python requests and HTTPie snippets. Requests go straight from your tab to the API — no proxy, no server, no logging — so cross-origin endpoints must return CORS headers for the browser to expose the response.
