Frequently asked questions
How much does Veo 3.1 Quality cost?
Veo 3.1 Quality starts at $1.8 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 get an API key for Veo 3.1 Quality?
Sign up for API Stock, top up your balance by any amount 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 Veo 3.1 Quality.
How do I call the Veo 3.1 Quality API?
Send a POST request to https://api.api-stock.com/api/v1/generation/create with your API key and the model id "veo3.1-quality". 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 Veo 3.1 Quality accept?
Veo 3.1 Quality accepts 5 input parameters, including the required field(s) prompt. Their types, defaults and allowed values are listed in the parameters table above.
What happens if a Veo 3.1 Quality 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 Veo 3.1 Quality 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 Veo 3.1 Quality without new credentials.
