Claude Code integration
Claude Code API key setup with prepaid controls
Claude Code can create valuable AI workflows, but long context windows, tool loops, and high-output tasks can make spend hard to predict. NexRelay gives developers running Claude-style coding workflows a controlled gateway key before scaling usage.
How Claude Code fits
Claude Code belongs to Claude-compatible message 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
Use the Claude-compatible messages endpoint with a scoped key and conservative output caps.
- 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 Claude Code use a NexRelay API key?
Claude Code 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 Claude Code?
A separate key makes spend easier to cap, audit, rotate, and disable without affecting other tools.
