About API Tester

Test any REST API directly from your browser — no installation required. Send GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests with custom headers, query parameters, request body (JSON, form, or raw text), and authentication (Bearer token or Basic Auth). Responses are displayed with syntax-highlighted JSON, status codes, timing, size, and response headers. Includes request history, curl export, and a server-side proxy that bypasses CORS restrictions.
