Model not allowed on this key

Retrying the identical request will fail the same way. Change the request first.

Code: model_not_allowed
HTTP: 403
Retry: Do not retry

The message

error.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

Example values.

The fix

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