How much does Wan 3.0 Pro cost?

Wan 3.0 Pro starts at $0.086 per second of output 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.

When was Wan 3.0 Pro released?

Wan 3.0 Pro was released on October 11, 2026. It is available through the API Stock API with the same key and prepaid balance as every other model.

How do I get an API key for Wan 3.0 Pro?

Sign up for API Stock, top up your balance using an available payment method and create an API key in the dashboard — it takes a couple of minutes and needs no contract. The same key works with every model in the catalog, so there is no separate key to obtain for Wan 3.0 Pro.

How do I call the Wan 3.0 Pro API?

Send a POST request to https://api.api-stock.com/api/v1/generation/create with your API key and the model id "wan3.0-video-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 input parameters does Wan 3.0 Pro accept?

Wan 3.0 Pro accepts 13 input parameters. Their types, defaults and allowed values are listed in the parameters table above.

What happens if a Wan 3.0 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 Wan 3.0 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 Wan 3.0 Pro without new credentials.
