Cursor IDE
Describe the Bug
Hi team,
After updating to the latest version (v1.6.46, Windows 10 x64), Cursor shows the following error whenever I try to use AI features:
{
“error”: “ERROR_DEPRECATED”,
“details”: {
“title”: “Request type deprecated.”,
“detail”: “This endpoint is deprecated. Please upgrade to the latest version of Cursor.”,
“isRetryable”: false
},
“isExpected”: false
}
Steps I tried:
- Reinstalled v1.6.46 (system setup)
- Downgraded to v1.5.x
- Cleared cache and config files
- Tried different networks
The issue persists.
Looks like Cursor is still calling the old api.cursor.sh endpoint which seems to be deprecated.
Questions:
- Will v1.6.47+ fix this by switching to
api.cursor.com? - Is there a temporary workaround for current users?
Environment:
- Windows 10 x64 (Build 26100)
- Cursor v1.6.46 (system setup)
- VSCode version 1.99.3
Steps to Reproduce
Open Cursor v1.6.46 (system setup, Windows 10 x64)
Try to use any AI feature (chat or code generation)
Error message appears: ERROR_DEPRECATED
Expected Behavior
AI features should work without error.

Additional Information
Cursor is unusable due to this error.
It seems related to deprecated API endpoint (api.cursor.sh).
