## Errors & retries

- `400` Fix the fields listed in `errors` before retrying.

- `428` Connect the requested website account using the returned sign-in link.

- `429` Wait for the duration in `Retry-After`.

- `5xx` Retry transient failures with backoff. Keep the request ID.

A failed run has its own error inside the response. Retry it only when `error.retryable` is true.
