REST API Tester
Send a real HTTP request to any API endpoint from your browser and see the live status, response headers, response body, and response time.
Enter an API endpoint and method below to send a real request directly from your browser, and see the live status code, response headers, response body, and response time.
This request is sent directly from your browser to the target URL - nothing passes through our servers. If the target API doesn't allow cross-origin requests (CORS), your browser will block the response even though the request itself may have succeeded; that's expected browser security behavior, not a bug in this tool.
Requests are sent directly from your browser to the target API - nothing passes through our servers, and we never see or store your request or response data.
What Is a REST API Tester?
A REST API tester lets you send a real HTTP request to an API endpoint and inspect exactly what comes back - status code, response headers, response body, and how long it took - without installing a desktop application.
Why Use This Tool?
Useful for quickly checking whether an endpoint is reachable, verifying a response shape while building an integration, confirming authentication headers are accepted, or debugging an unexpected status code during development.
How to Use the REST API Tester
- Enter the full API endpoint URL.
- Choose an HTTP method.
- Add any headers your request needs (for example, an Authorization header).
- For methods that support a body, enter it and select the content type.
- Click Send Request and review the result panel.
Understanding the Result
- Status - the HTTP status code and text returned by the server.
- Response time - how long the request took, measured in your browser.
- Response headers - every header the server sent back.
- Response body - the raw response, formatted automatically if it is JSON.
About CORS
Because this request is sent directly from your browser (not a server), the target API must allow cross-origin requests (CORS) from this site, or the browser will block the response even though the request may have actually succeeded server-side. If a request fails with a network/CORS error rather than a real HTTP status, that is almost always the reason - it is a browser security restriction, not a bug in this tool.
Limitations
Avoid testing endpoints that require sensitive, long-lived credentials - treat this the same as any third-party client and use short-lived or test credentials where possible.
