What does this API error mean?

The decoder uses the message and error code together. Include the provider when the same status could mean different things.

An OpenAI 429 with insufficient_quota points to billing or the project budget. A rate limit can call for lower concurrency or a delayed retry.

Limitations

A code is a clue. Confirm billing, limits or access in your provider account.
