Errors | Mistrounter Docs

Errors use a consistent JSON envelope:

{
  "error": {
    "type": "invalid_request_error",
    "code": "unsupported_duration",
    "message": "Duration must be one of: 5, 10.",
    "param": "duration"
  }
}

HTTP	Meaning	Retry?
`400`	Invalid JSON, parameter, model option, or idempotency key	Fix request
`401`	Missing, invalid, or revoked API key	Replace key
`402`	Insufficient credits	Add credits
`413`	Request body is too large	Reduce request size
`429`	API-key rate limit exceeded	Retry with backoff
`404`	Generation not found for this account	Do not retry
`500`	Unexpected Mistrounter error	Retry with backoff
`502`	Upstream provider rejected submission	Safe to retry with the same idempotency key
`503`	Video provider is not configured or temporarily unavailable	Retry later

Retry network errors and 5xx responses with exponential backoff and jitter. Always reuse the original Idempotency-Key; do not automatically retry other 4xx responses.
