Runway API through YepAPI
YepAPI provides access to Runway models through a unified API endpoint. Instead of managing a separate Runway API key and billing account, use your single YepAPI key to call any Runway model alongside 265 other AI models from OpenAI, Anthropic, Google, Meta, and more.
All Runway models use the same OpenAI-compatible request format. Switch between models by changing the model parameter — no SDK changes, no code rewrites. Pay per token with no monthly minimums.
