把视频创作接入你的应用。

# 需要 curl 和 jq；先在运行环境设置 H3_API_KEY
BASE_URL='https://你的域名'
: "${H3_API_KEY:?请先设置 H3_API_KEY}"

# 1. 读取当前可用参数（能力会随配置、售价与时段变化）
curl --fail-with-body -sS "$BASE_URL/v1/capabilities?model_id=h3-video" | jq

# 2. 获取报价；示例参数须在上面的 variants 中受支持
PARAMS='{"model_id":"h3-video","resolution":"480p","duration":5,"aspect_ratio":"landscape","mode":"text","image_count":0}'
QUOTE=$(curl --fail-with-body -sS "$BASE_URL/v1/quote" \

  -H 'Content-Type: application/json' -d "$PARAMS") || exit 1
printf '%s\n' "$QUOTE" | jq '.quote | {amount, currency, breakdown, valid_until}'

# 3. 确认费用后提交（会冻结真实余额）
printf '输入 yes 确认本次费用：'

# BODY=$(jq -c '.body' "$PENDING_FILE")

# 4. 每隔 3 秒查询；succeeded 后下载，failed 后已自动解冻
curl --fail-with-body -sS "$BASE_URL/v1/generations/$JOB_ID" \
  -H "Authorization: Bearer $H3_API_KEY" | jq
# 仅在 status=succeeded 且 result.state=available 后执行：
# 将查询响应的 result_url 保存为 RESULT_URL，先鉴权取得签名地址再单独下载：
