OpenClaw + Runway Questions
Can I use Runway video generation in OpenClaw?
Yes. With RunAPI configured as a provider in OpenClaw, the agent can call the Runway endpoints shown on this page using your RunAPI API key.
Can I extend a Runway video after generating it?
Yes. Call the extend endpoint with the task from the original generation and a new prompt, and the extension continues the existing clip.
Is Runway generation asynchronous?
Yes. The create endpoint returns a task ID immediately. Poll the task status or provide a callback URL to receive a webhook when the video is ready.
Which model ID should I use?
Choose a public model ID from the version table. Each ID exposes the endpoints shown for that version.
Does this guide configure a chat model?
No. This Model Line uses the endpoint workflow shown here and is not presented as an agent chat model.
