- `401`: **Unauthorized:** The provided API key is invalid or absent. Provided in the request API key is not valid or is missing.
- `402`: **Payment Required:** Not enough credits to perform this request. The plan allows this call but the credit balance does not cover it. Top up credits and retry. Amounts are in milli-credits (1 credit = 1000).
- `403`: **Forbidden:** Access to this resource is not allowed. User does not have permission to access this feature.
- `404`: **Not Found:** Requested resource could not be found on the server. Specific resource with the provided ID cannot be found.

- `429`: **Too Many Requests:** The request rate limit has been reached. Retry after the interval indicated by the response headers.
- `503`: **Service Unavailable:** Credit accounting is temporarily unreachable. The request was refused rather than served without being billed. This is transient — retry with backoff.
