Routing & failover
You always pass the platform alias (e.g. gpt-5.2), never the upstream-specific id (e.g. openai/gpt-5.2). Behind the scenes:
- Each alias maps to one or more upstream routes ordered by priority.
- Each route consumes credentials from a per-provider pool. If a credential gets repeatedly rejected, it's cooled down for 60s and the next request picks a sibling.
- A single retryable upstream error (5xx, 401/403 token issues, 429 rate limit) triggers the relay to retry the next candidate automatically — your client only sees the final result.
- If every candidate is exhausted, you get an explicit
503 with a clear message instead of a stuck request.
See Common errors for what each status code means and how to react.
