Seedance Python SDK for RunAPI

The Seedance Python SDK is the language-specific package for Seedance on RunAPI. Use this package for video generation, animation, and video editing workflows when your application needs request bodies, task status lookup, and consistent RunAPI errors in Python.

This README is the Python package guide inside the public seedance-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/seedance; for API reference, use https://runapi.ai/docs/api/seedance/text-to-video; for SDK docs, use https://runapi.ai/docs/resources/sdks.

Install

pip install runapi-seedance

Quick start

from runapi.seedance import SeedanceClient

client = SeedanceClient()  # reads RUNAPI_API_KEY, or pass api_key="sk-..."

task = client.text_to_video.create(
    model="seedance-2.0",
    prompt="A cat walking through a garden",
    duration_seconds=8,
)
status = client.text_to_video.get(task.id)

Use create to submit a task and return quickly, get to fetch the latest task state, and run when a script should create and poll until completion:

result = client.text_to_video.run(
    model="seedance-2.0",
    prompt="A cinematic drone shot over snowy mountains",
    duration_seconds=8,
)
print(result.videos[0].url)

In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.

Language notes

Pass parameters as keyword arguments and catch the runapi.seedance error classes when building video jobs or scripts. The available resource is text_to_video. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
