⚠️ 注意 / Note

• 本接口不计费。 响应 JSON 中的 message / message_zh 是全局默认文案 （「本次请求将被计费」），对本接口不适用，请忽略。

• 有 RPS 限流，请按每秒 1 次的频率轮询。 超出路由限流会返回 429 （响应头 Retry-After: 1）；限流按「用户 + 路由」单独计算。

• This endpoint is free of charge. The message / message_zh fields in the response JSON carry a global default notice ("this request will incur a charge") that does not apply here — please ignore them.

• This endpoint is rate limited — poll at no more than 1 request per second. Exceeding the route's limit returns 429 with a Retry-After: 1 header. The limit is tracked per user per route.

用途:

• 获取异步任务的抓取结果。本端点不计费，三个创建任务端点通用， 且在 30 天保留期内可重复获取。
• 结果未就绪时返回 ready = false 且 records 为空数组（不报错）， 稍后退避重试即可。

参数:

• task_id: 创建任务时返回的 task_id（形如 sd_xxxxxxxxxxxxxxxxxx）。

返回:

• task_id: 任务 id； ready: 结果是否已就绪； status: ready（已就绪）或 not_ready（仍在执行）； records: 抓取结果数组，内容与对应的同步端点一致；未就绪时为空数组。
• 目标页面被隐藏 / 不存在时，records 的元素内会带 error / error_code 字段，与同步端点行为一致。
• task_id 格式非法、不存在或已过期（超过 30 天）时返回 400。

Purpose:

• Fetch the result of an async task. This endpoint is free, is shared by all three task-creation endpoints, and can be called repeatedly within the 30-day retention window.
• While the result is not ready it returns ready = false with an empty records array (not an error) — retry later with a backoff.

Parameters:

• task_id: The task_id returned on creation (looks like sd_xxxxxxxxxxxxxxxxxx).

Returns:

• task_id: the task id; ready: whether the result is ready; status: ready, or not_ready while still running; records: array of scraped results, identical in shape to the matching synchronous endpoint; an empty array while not ready.
• If the target page is hidden or does not exist, the element inside records carries error / error_code fields, matching the behaviour of the synchronous endpoints.
• Returns 400 if the task_id is malformed, does not exist, or has expired (over 30 days).
