How to call Seedance 2.5
The API is OpenAI-compatible. Replace YOUR-ENDPOINT with the endpoint shown on your API Key page after you sign up, and YOUR-KEY with your key.
curl https://YOUR-ENDPOINT/v1/video/generations \
-H "Authorization: Bearer YOUR-KEY" \
-H "Content-Type: application/json" \
-d '{"model": "bytedance/seedance-2-5", "prompt": "a red panda walking in the snow", "duration": 5}'Video is generated asynchronously: you get a task ID back and poll for the result (see the docs). You're billed for the seconds actually generated; failed jobs are free.
