Frequently asked questions
Does Runway have API?
Yes. Runway Dev provides asynchronous APIs and official SDKs for video, image, audio, transformation, upscaling, and real-time character workflows.
How much does Runway API cost?
Runway API credits cost $0.01 each with a documented minimum initial purchase. Each operation consumes a model- and format-dependent number of credits, so output duration, resolution, and model choice determine the final cost.
Is Runway for free?
Runway may offer limited consumer access, but its API does not document a general free generation tier. API organizations purchase credits, and application usage is billed separately from consumer plans.
