API Request Tester
Send HTTP requests from the browser and inspect status, headers, and response bodies.
Headers / Status
Response body
Browser CORS rules still apply. If the target API blocks browser requests, the fetch will fail even though the endpoint itself may be live.
What An API Request Tester Does
An API request tester lets you send HTTP requests and inspect the response status, headers, and body without leaving the browser. It is useful for quick testing, debugging, and endpoint verification.
Browser Limitations Still Apply
Because this tool runs in the browser, it is still subject to CORS restrictions. Some APIs may be reachable from servers or Postman but not directly from a browser page.
Best Use Cases
Use it for public APIs, test endpoints, debugging JSON responses, and verifying that an endpoint returns the shape or status code you expect.
