About this tool
Test REST API Server is a static, browser-based client. Test REST API Server sends HTTP requests from your browser to the API endpoint you enter and shows the status, headers and body of the response.
Because the call is made by your browser, it follows the same CORS rules as any web page, so some cross-origin APIs may refuse to respond. The request is sent from your browser straight to the API you name; this site has no backend and never receives it, though that server and your network can see it. Cross-origin calls follow the browser's CORS rules, and a connection is required.
Frequently asked questions

Does Test REST API Server send my request anywhere?
Yes — Test REST API Server sends the request from your browser directly to the URL you enter. This site has no backend and never receives it, but the target server and your network do, and cross-origin calls follow browser CORS rules.
Can Test REST API Server call any API from the browser?
Test REST API Server can call any endpoint your browser is allowed to reach, but cross-origin APIs must send permissive CORS headers or the browser will block the response — that is a browser rule, not a limit of Test REST API Server.
