Processing...
How to use
- 1 Enter the API endpoint URL and pick a method (GET, POST, PUT, PATCH or DELETE).
- 2 Add any request headers, query parameters or a JSON/raw body your endpoint expects.
- 3 Click Send; the request is routed through a CORS-bypass proxy so browser cross-origin limits do not block it.
- 4 Inspect the response status, headers and formatted body, then tweak and resend to debug your API.
Frequently Asked Questions
Is this REST API tester free to use?
Yes, it is completely free and runs in your browser with no signup or install required.
Why can I not reach my localhost or internal API?
The proxy used to bypass CORS deliberately blocks private and localhost IP ranges for security, so it only works with publicly reachable URLs.
Does it support custom headers and authentication?
Yes, you can add any headers including Authorization tokens, API keys and content-type to authenticate your requests.
