Frequently asked questions
How much does Seedance 1.5 Pro cost?
Seedance 1.5 Pro starts at $0.068 per generation through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.
How do I call the Seedance 1.5 Pro API?
Send a POST request to https://api.api-stock.com/api/v1/generation/create with your API key and the model id "doubao-seedance-1-5-pro". The call returns a task id you poll, or a webhook callback when the result is ready. A ready-to-run example is in the quick start above.

What happens if a Seedance 1.5 Pro request fails?
API Stock automatically retries the request on a reserve provider. If every provider fails, the charge is refunded to your balance.
Can I use Seedance 1.5 Pro with the same API key as other models?
Yes. Every model on API Stock — video, image, music and chat — shares one API key and one prepaid balance, so you can switch to Seedance 1.5 Pro without new credentials.
