API Request Builder

Build and send HTTP requests visually with headers, query params, body, and auto-generated cURL/fetch code

How it works

  • • Build HTTP requests visually — set method, URL, headers, query params, and body.
  • • Click Send to make the request directly from your browser.
  • • View response status, timing, and body with syntax highlighting.
  • • Auto-generates equivalent cURL and fetch() code snippets.
  • • Note: CORS restrictions may prevent some APIs from responding in the browser.
