Cursor integration
Cursor API key setup with prepaid controls
Cursor can create valuable AI workflows, but large files, repeated edits, and broad model access can make spend hard to predict. NexRelay gives developers who want editor AI features with clearer API spend limits a controlled gateway key before scaling usage.
How Cursor fits
Cursor belongs to OpenAI-compatible editor clients. The safest setup is a dedicated gateway key, a compatible endpoint, and a small first budget so one client can be tested without exposing a broad provider key.
Recommended setup
Create a Cursor-only key and route compatible requests through the NexRelay base URL.
- Create one key for this client only
- Start with a small daily or monthly budget
- Use model allowlists for early testing
- Review request logs after the first successful call
What to verify
After the first request, check that the expected model, endpoint, token meters, billed amount, and status appear in the usage ledger. Increase limits only after the route behaves as expected.
FAQ
Can Cursor use a NexRelay API key?
Cursor can use NexRelay when the client supports a compatible custom base URL and API key for its request style.
Why use a separate key for Cursor?
A separate key makes spend easier to cap, audit, rotate, and disable without affecting other tools.
