About CORS and Browser Requests

Requests from this tool run directly in your browser using the Fetch API. Due to CORS (Cross-Origin Resource Sharing) restrictions, some servers will block requests that originate from a different domain. If you encounter a CORS error, try the generated curl command in your terminal, or test against APIs that explicitly allow cross-origin requests like jsonplaceholder.typicode.com or httpbin.org.
