Test any REST API without leaving the browser
Compose a request with any method, headers and body, send it, and read the full response — status, timing, headers and pretty-printed JSON — with nothing to install.
Runs in the API Inspector — no account, nothing to install.
Sample report · illustrative data
Everything the report surfaces
Every method
Send GET, POST, PUT, PATCH and DELETE with full control over query parameters, headers and request body.
Response inspection
See the status code, response headers, timing and a formatted JSON body, so you can verify the contract at a glance.
Custom headers & auth
Set Authorization, Content-Type and any custom header to test authenticated and content-negotiated endpoints.
Timing breakdown
Reports how long the request took so slow endpoints are visible before they reach production.
Three steps to a full answer
Compose the request
Choose a method, enter the endpoint, and add any headers or body the API expects.
Send it
The API Inspector issues the request and captures the complete response and its timing.
Inspect the response
Read the status, headers and formatted body, and iterate on your request until the contract behaves as expected.

Common questions
Can I send POST and other methods, not just GET?
Yes. The tester supports GET, POST, PUT, PATCH and DELETE, with full control over the request body and headers, so you can exercise a complete REST contract.
Can I set authentication headers?
Yes. Add an Authorization header — bearer token, basic auth or an API key header — along with any custom headers the endpoint requires.
Does it format the JSON response?
The response body is pretty-printed and the status, headers and timing are shown alongside it, so you can read and verify the payload quickly.
Do I need to install anything?
No. The API Inspector runs in the browser with no desktop client, extension or account required.
