HIP-4 questions

- ApiResponseHip4QuestionArray: API response containing HIP-4 questions.
  - `success` boolean
  - `data` Hip4Question[]
    - `question_id` integer, required: Question identifier.
    - `name` string, required: Question name as published on-chain (recurring markets use a generic name such as `Recurring`).
    - `description` string, required: Pipe-delimited question metadata (class, underlying, expiry, price thresholds, period).
    - `fallback_outcome_id` integer, required: Outcome ID that resolves Yes when no named outcome does.
    - `named_outcome_ids` integer[], required: Outcome IDs of the named choices grouped under this question.
    - `settled_named_outcomes` integer[], required: Subset of `named_outcome_ids` that have already settled.
    - `first_seen_at` string, date-time, required: When this question was first observed by 0xArchive (UTC).
    - `last_updated_at` string, date-time, required: When this question row was last updated (UTC).
  - `meta` ResponseMeta: Response metadata. Every 2xx JSON response carries `meta.request_id`; list payloads add `count`; cursor-paged routes add `has_more` and, when another page follows, `next_cursor`; per-symbol routes add `symbol` and `venue`. Fields that do not apply to a route are omitted.
    - `count` integer: Number of records returned
    - `has_more` boolean: Cursor-paged routes: whether another page follows. `next_cursor` is present exactly when this is `true`. A final page can be empty when the previous page was exactly full; `has_more` is `false` on it.
    - `next_cursor` string: Opaque cursor for the next page, present exactly when `has_more` is `true`. Pass it back unchanged as `cursor` with the same filters. Do not parse or construct it.
    - `request_id` string, uuid, required: Unique request ID for support
    - `symbol` string: Per-symbol routes: the canonical public symbol the response describes (for example `BTC`, `xyz:TSLA`, `HYPE-USDC`, `#0`).
    - `venue` 'hyperliquid' | 'hip3' | 'hip4' | 'spot' | 'lighter' | 'rh-lighter': Per-symbol routes: the venue the response describes.
    - `coverage_from` string, date-time: Earliest coverage for the requested symbol and data type. Present only when the requested window ends before coverage begins.
    - `notice` string: Human-readable advisory about the response. Used when the requested window ends before coverage begins for the symbol, and on CVD responses that are one page of several; may carry other advisories in future.
    - `finalized_through` string, date-time: Two-tier datasets (Lighter trades): data at or before this instant is final; later data is preliminary.
    - `requested_end` string, date-time, nullable: The `end` the request asked for, echoed when it was clamped to `finalized_through`.
    - `clamped_to` string, date-time, nullable: The boundary the request's `end` was clamped to, when clamping occurred.
    - `preliminary_row_count` integer, nullable: Number of preliminary rows in this response, on routes that intentionally serve preliminary data (Lighter `/recent`).

## Other responses

- `400`: Invalid request: a parameter, symbol, interval, cursor or time range failed validation. See `error_code`.
- `401`: Authentication required: the API key is missing or invalid.
- `403`: The request is outside the plan's history window or per-request span, or the key is not allowed to make it.
- `429`: Rate limit, concurrency limit or monthly credits exceeded. See `error_code`.
- `default`: Any other error. The body is an `ErrorResponse`; branch on `error_code`. A 503 (`upstream_unavailable`) carries `Retry-After`.
