Runway
Video, image and audio generation API with Runway's Gen models plus Veo, Seedance and Wan behind one key
Runway Dev is the developer API of Runway, the company behind the Gen video models. One API key reaches Runway's own models (Gen-4 Turbo, Gen-4.5, Aleph 2) alongside models from other labs, among them Google Veo 3.1, ByteDance Seedance 2.5 and Wan 3.
Billing is in credits at $0.01 each, charged per second of video: Gen-4 Turbo costs 5 credits a second and Gen-4.5 costs 12. A model router can pick the model per request by cost, latency or quality. The API also covers image generation, upscaling and audio, with an MCP server for agents.
Pricing: Pay-as-you-go
