How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
A JSON object containing the job ID (jobId), generation type ('seedance-fast-t2v'), current status ('pending'), and a success boolean. The agent must poll a separate endpoint using the jobId to retrieve the completed video once processing is done.
Example use cases
Create promotional video from product description
“Generate a video for our new smartwatch product. I need it to show the device glowing on a sleek black table with soft blue lighting, rotating slowly to display all angles. Make it cinematic and modern.”
Turn social media caption into video clip
“We have a TikTok caption that says 'sunset over the ocean with silhouettes dancing on the beach.' Can you create an actual video from that description? We need it quick and don't want to commit to a subscription.”
Generate AI video for educational content
“I'm making a science explainer video about DNA replication. Create a short animated-style video showing DNA strands unwinding and separating, with a blue glow effect, at high quality so it looks professional in our course materials.”
Technical details
Endpoint
POSThttps://stablestudio.io/api/generate/seedance-fast/t2vWhen to prefer
Choose this endpoint when you need to generate a short video from a text prompt using the Seedance Fast model with pay-per-use pricing (no subscription required). Prefer this over image-generation endpoints when the output must be a video clip. Best for one-off or infrequent generation tasks where a subscription model is undesirable. Note the $20 USDC cost per call and asynchronous (job-based) response pattern.
Side effects
- Missing or empty prompt returns a validation error
- Prompt exceeding 10,000 characters is rejected
- Invalid enum value for resolution, aspect_ratio, or output_format causes a 400 error
- Payment of $20 USDC not received causes a 402 Payment Required response
- Safety tolerance out of range (below 1 or above 5) causes a validation error
- Output quality out of range (below 0 or above 100) triggers a validation error
- Service may return a failed job status upon polling if generation fails internally
