        Error identifier. For domain rejections and transport errors
        (`401`/`404`/`429`/`500`) this is a stable, machine-readable snake_case
        identifier that is part of the API contract and safe to branch on, e.g.
        `insufficient_margin`, `insufficient_balance`, `order_not_found`,
        `reduce_only_invalid`, `unauthorized`, `not_found`. For `400` it is a
        human-readable validation detail whose wording may change. See the Error
        handling guide for the domain identifiers. (Post-only / Fill-or-Kill
        outcomes are order statuses such as `post_only_rejected`, not
        rejections.)
      example: insufficient_margin

    Error400Response:
      description: |
        Bad request — the request was malformed or failed validation (bad query
        parameters, unparseable body, invalid signature, or a domain pre-check).
        The `error` field is a human-readable validation detail.

    Error429Response:
      description: >
        Too Many Requests. `error` distinguishes the limit that was hit:

        `ip_rate_limited` (per-IP token bucket), `action_rate_limited`
        (per-account

        action rate), or `open_orders_limit` (resting open-order cap).

        Retry-After:
          description: >
            Whole seconds to wait before retrying. Present only on token-bucket

            rate-limit rejections (`ip_rate_limited` and `action_rate_limited`);
            a

            conservative estimate of when enough capacity will have refilled to

            admit the request. Absent on `open_orders_limit`, which is a
            capacity

            limit, not a rate limit — waiting does not free order slots; cancel

            resting orders or wait for fills instead.
