AI Video API

AI Video API is a developer-focused API hub for generating AI videos, positioned as a cheaper alternative to going directly through underlying video-generation providers. Developers send a text prompt or a source image and the service returns a rendered video, with the platform highlighting support for clips up to 36 seconds, longer than what it describes as the typical industry limit. Output can be delivered as both video and an optimized GIF, and the API supports webhook alerts and status polling so integrations can track a generation job without constant checking. Under the hood, the platform builds on RunwayML's video models, including its Gen-4 model, and offers official client support for Python, Node.js, JavaScript, and PHP, plus a listing on the RapidAPI marketplace. Pricing is tiered from a free Starter plan covering five generations a month up to an Ultra plan at roughly $40 a month for up to 250 generations, marketed as up to three times cheaper than comparable services. The tool is built for developers, creative directors, and freelance digital artists who want to add video generation to an app or workflow without building infrastructure around a video model directly. One limitation: because it is a wrapper around RunwayML, its feature set and quality are bounded by whatever RunwayML currently supports.
