Open WebUI integration
Open WebUI API key setup with prepaid controls
Open WebUI can create valuable AI workflows, but shared user traffic and unclear per-user usage can make spend hard to predict. NexRelay gives teams running a self-hosted chat UI with external model access a controlled gateway key before scaling usage.
How Open WebUI fits
Open WebUI belongs to OpenAI-compatible web UI 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
Point Open WebUI at the compatible endpoint and keep one key per environment.
- 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 Open WebUI use a NexRelay API key?
Open WebUI 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 Open WebUI?
A separate key makes spend easier to cap, audit, rotate, and disable without affecting other tools.
