API error FAQ

vpn_key_alert

Why can a valid key still fail?

A key can authenticate successfully but still lack access to a model, organization, billing plan or relay-specific route.

speed

Does 429 mean the key is banned?

Usually no. 429 means rate limit or quota throttling. Reduce concurrency, add backoff, or compare relay limits.

view_list

How do I tell model_not_found from relay mismatch?

First list available models with the key checker. If the model is absent, use the exposed alias or choose a relay that supports it.
