About Sisif
Sisif is a text-to-video generation API that allows developers and creators to programmatically generate AI videos with a simple REST endpoint. It offers multiple style options such as anime, vaporwave, comic book, 3D animation, pixel art, and CCTV footage. Users can choose from two vertical resolutions (540x960 and 720x1280), set durations, and receive videos via polling or webhooks. The platform includes an n8n integration for automating workflows, a free tier with 35 credits (no credit card required), and paid plans starting at $10/month. Videos can be used commercially. The team is based in Timișoara, Romania, and focuses on fast iteration and quality.
