Model not allowed on this key

HTTP 403 · retrying the identical request will fail identically — change the request first.

The message

'openai/gpt-5.5' exists but this API key's policy does not allow it. Did you mean 'openai/gpt-5.5-mini'? Allowed models are set per key at https://minirouter.sh/dashboard/keys and per guardrail at https://minirouter.sh/dashboard/guardrails

Values are examples; the live message carries your request’s real figures.

The fix

Pick a model the key allows, or widen the key or guardrail allowlist. The account-wide list on /dashboard/routing also applies.
