How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
A JSON object containing the job type ('seedance-fast-i2v'), a unique jobId string for polling the generation status, a status field (initially 'pending'), and a success boolean confirming the job was accepted.
Example use cases
Example prompt
“On StableStudio, animate this image into a short video — use the prompt 'a futuristic cityscape with flying cars and glowing neon lights at night', output at 1 MP resolution in 16:9 widescreen format, and let the model enhance my prompt for more creative results.”
Technical details
Endpoint
POSThttps://stablestudio.io/api/generate/seedance-fast/i2vWhen to prefer
Choose this endpoint when you need to generate a video from an image using the Seedance Fast model with pay-per-use pricing (no subscription required). Prefer this over subscription-based video generation services when you need occasional or one-off video generation. Use when async job-based workflows are acceptable and you can poll for results using the returned jobId.
Side effects
- Missing required 'prompt' field returns a 400 validation error
- Prompt exceeding 10,000 characters is rejected
- Invalid enum values for resolution, aspect_ratio, or output_format return validation errors
- Payment of $20 USDC not provided or insufficient balance causes payment failure
- Safety tolerance violations may cause content rejection
- Service may be temporarily unavailable, returning 5xx errors
- Job creation succeeds but async generation may fail — must poll jobId to confirm completion
