Runway Python SDK for RunAPI

The Runway Python SDK is the language-specific package for Runway 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 runway-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/runway; for API reference, use https://runapi.ai/docs#runway; for SDK docs, use https://runapi.ai/docs#sdk-runway.

Install

pip install runapi-runway

Quick start

from runapi.runway import RunwayClient

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

task = client.text_to_video.create(
    model="...",
    prompt="A drone shot over a coastal city at sunset, cinematic",
    duration_seconds=5,
    output_resolution="720p",
    aspect_ratio="16:9",
)
status = client.text_to_video.get(task.id)

extended = client.extend_video.create(
    model="...",
    source_task_id=task.id,
    prompt="Continue the camera push toward the harbor",
    output_resolution="720p",
)

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

result = client.text_to_video.run(
    model="...",
    prompt="A serene mountain lake at dawn, slow pan",
    duration_seconds=5,
    output_resolution="720p",
)
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.runway error classes when building video jobs, workers, or scripts. The available resources are text_to_video and extend_video. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
