如何按 task_id 查一條 Seedance 影片的真實消費？

curl --compressed -s "https://api.apiyi.com/api/task/self?p=1&page_size=1&task_id=<你的 task_id>" \
  -H "Authorization: $APIYI_SYS_TOKEN" | jq '.data.items[0] | {task_id, status, quota, submit_time, finish_time}'

import os, time, requests

    """返回 (status, 美元消費)。失敗任務消費為 0，進行中返回 None。"""
    r = requests.get(f"{BASE}/api/task/self", headers=HEADERS, timeout=60,
                     params={"p": 1, "page_size": 1, "task_id": task_id})
    r.raise_for_status()
    items = r.json()["data"]["items"]
    if not items:

        return status, 0.0
    return status, None          # submitted / in_progress：quota 只是預扣，先別記賬
