CORS Error
The request was blocked by the browser's Cross-Origin Resource Sharing (CORS) policy. This is a browser security feature, not a bug in this tool.
- The target API may not include the required CORS headers (Access-Control-Allow-Origin).
- Consider using a CORS proxy service to relay requests.
- If you control the API, add appropriate CORS headers to allow browser requests.
- For local development, test from a server-side environment instead.
