wan2.7-t2v (text-to-video). Ей нужен только текстовый prompt, без медиа. Чтобы заставить изображение двигаться или сохранить особенности объекта, используйте Изображение-в-видео / Референс-в-видео вместо этого.

Формат ответа

Проверка статуса и скачивание
Как только у вас естьtask_id, выполните эти три шага, чтобы опрашивать статус и скачать mp4:
- Проверяйте
GET /v1/tasks/{task_id}(сAuthorization; запросу не нужен заголовокX-DashScope-Async), каждые 5-10 секунд (не < 3 секунд), покаstatusне станетcompleted. - Значения статуса:
submitted(queued) /in_progress(generating;progress, часто застревающий на 30%, — это нормально) /completed(success) /failed(проверьтеerror). - Скачивание: выполните GET
result_urlнапрямую из ответа, без заголовкаAuthorization(это подписанная прямая ссылка OSS — при отправке Auth возвращается 403);result_urlпо умолчанию истекает через 24 часа, так что сохраните его сразу.
curl "https://api.apiyi.com/v1/tasks/c2e7570c-0af2-4eba-919f-3af3d1164a38" \
-H "Authorization: Bearer sk-your-api-key"
{
"status": "completed",
"progress": 100,
"result_url": "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=...",
"task_id": "c2e7570c-0af2-4eba-919f-3af3d1164a38"
}
# result_url is an OSS signed direct link — do NOT send the Authorization header (it returns 403)
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."
TASK_ID="c2e7570c-0af2-4eba-919f-3af3d1164a38"
URL=$(curl -s "https://api.apiyi.com/v1/tasks/$TASK_ID" \

curl -L -o out.mp4 "$URL" # no Authorization
