The Runway Video Generation API allows developers to generate videos from text prompts, images, or existing videos using Runway's Gen-4 and Gen-4.5 models. The API supports text-to-video, image-to-video, and video-to-video generation workflows, producing 5-8 second video clips. Tasks are processed asynchronously, with developers submitting generation requests and polling for results using unique task identifiers. Authentication is handled via Bearer token in the HTTP Authorization header.

The Runway Image Generation API provides a text-to-image endpoint that enables developers to generate high-quality images from text prompts using Runway's Gen-4 model. The API accepts text descriptions and produces images as output, allowing integration of AI-powered image generation into applications, products, and platforms. Like the video API, it uses asynchronous task processing and Bearer token authentication.

The Runway Characters API enables developers to build real-time conversational avatars powered by GWM-1, Runway's General World Model. Characters are fully custom conversational video agents that can be created from a single image with no fine-tuning required, supporting photorealistic or animated styles, human or non-human appearances. The API uses WebRTC sessions for live conversations with up to 5-minute duration, and includes a Documents API for uploading domain-specific knowledge that avatars can reference during interactions.
