使用 CometAPI 的 POST /grok/v1/videos/generations 通过 Grok 创建视频,通过 prompt 让输入图片动起来,并通过 request_id 轮询结果。
curl --request POST \
--url https://api.cometapi.com/grok/v1/videos/generations \
--header 'Authorization: Bearer <token>' \
--header 'Content-Type: application/json' \
--data '
{
"prompt": "A candle flickers on a wooden table."
}
'{
"request_id": "4b2cd27e-0b0d-3dec-c31c-7572daf74bb3"
}request_id,因此应将其视为异步工作流的第一步。
