Seedance 1.5 Pro API — frequently asked questions
How do I use the Seedance 1.5 Pro API?
Install the official Node.js (npm install getimg-ai) or Python (pip install getimg) SDK, or call the endpoint directly over HTTP from any client.
Make a POST request to /v2/videos/generations with your API key and a JSON body containing the model ID (seedance-v1-5-pro) and a prompt. The API returns a request ID. Poll the status endpoint until the video is ready.
See the API documentation for the full parameter reference.
Which SDK should I use?
Use getimg-ai for Node.js and TypeScript projects, and getimg for Python. Both wrap the same REST API with typed inputs, retries, and built-in polling for video generations.
For other languages — Go, Rust, Java, Ruby, PHP — call the HTTP endpoints directly. Every example on this page includes a cURL snippet you can port to any HTTP client.
