How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
Returns a JSON object with a jobId (e.g. 'cmpbmzaee000j04jrzx4f43tw'), a status of 'pending', the model type 'veo-3.1-fast-video', and a success boolean. The agent must poll a separate status endpoint using the jobId to retrieve the final video once processing completes.
Example use cases
Example prompt
“Generate a video of a golden retriever running through a sunlit meadow with wildflowers, in 16:9 landscape format at 1 MP resolution — use Veo 3.1 Fast on StableStudio and enhance the prompt for more creative results.”
Technical details
Endpoint
POSThttps://stablestudio.io/api/generate/veo-3.1-fast/generateWhen to prefer
Choose this endpoint when you need fast, pay-per-use AI video generation powered by Google's Veo 3.1 Fast model with no subscription required. Ideal for agents or workflows that generate video infrequently or on-demand, paying only per generation. Prefer this over image endpoints when the output must be a video rather than a static image.
