Runway on RunAPI

Generate and edit video with Runway through RunAPI. The default path for one-off agent tasks is the runapi CLI; SDKs are for application integration.

Routing decision

• One-off generation, editing, or transformation for the user → use the CLI path with the runapi binary.
• Building an app, backend, worker, library, or production codebase → use the SDK integration path.

CLI path

The runapi binary is the runtime dependency. Authenticate with runapi login (browser) or set RUNAPI_API_KEY; a saved CLI config also works — no required environment variable.

Inspect the available actions and request fields with CLI help:

runapi runway --help
runapi runway text-to-video --help

Run a one-off task (synchronous — polls until the task completes):

runapi runway text-to-video --input-file request.json

Submit asynchronously and poll separately:

runapi runway text-to-video --async --input-file request.json
runapi wait <task-id> --service runway --action text-to-video

Available actions: text-to-video, extend-video.

SDK integration path

When integrating Runway into an app, backend, worker, or library — not for one-off tasks — use a RunAPI SDK package:

• JavaScript / TypeScript: @runapi.ai/runway
• Ruby: runapi-runway
• Go: github.com/runapi-ai/runway-sdk/go
