Runway

Runway (RunwayML) is a generative AI media platform whose developer API turns text, images, and video into new video, images, speech, and character performances. The REST API at https://api.dev.runwayml.com/v1 exposes Runway's Gen-4 and Gen-4 Turbo video models, Gen-4 Image text-to-image, the Aleph video-to-video editing model, and Act character performance, all through an asynchronous create-task-then-poll pattern authenticated with a Bearer API secret and a dated X-Runway-Version header. Access is API-key based via a developer organization; usage is billed in credits at roughly $0.01 per credit.

Runway publishes 8 APIs on the APIs.io network, including Character Performance API, Image-to-Video API, Organization API, and 5 more. Tagged areas include Video Generation, AI Video, Generative AI, Text-to-Video, and Image-to-Video.

Runway’s developer surface includes documentation, signup flow, engineering blog, authentication, pricing, and 12 more developer resources.
