Youart

YouArt is an all-in-one AI creative studio out of Y Combinator (founded 2025, San Francisco), positioned as "Patreon for AI Originals." It lets creators browse and run 60+ leading image, video, audio, and text-to-speech models — GPT Image 2, Nano Banana, Seedream, Sora 2, Kling, Veo 3, ElevenLabs v3, Suno — or compose them into multi-model, node-based creative workflows on a canvas. Agents and developers connect over a hosted, OAuth-secured Model Context Protocol (MCP) server to generate images, video, and audio and assemble workflows from chat, sharing the same account, credits, and projects as the web application. Creators can also launch original AI films and series, get funded directly by fans, and earn subscription revenue.

Youart publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Generative AI, Image-Generation, and Video Generation.

Youart’s developer surface includes documentation, API reference, pricing, support, authentication, and 7 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/youart: open an issue to ask a question, or submit a pull request to add artifacts.
