Moonvalley

Moonvalley is an AI research lab building Marey, a studio-grade generative video model for filmmakers. Marey generates cinematic image-to-video and text-to-video with precise creative controls — pose transfer, camera control, motion transfer, and trajectory control — and is trained exclusively on licensed data, which Moonvalley markets as a "commercially safe" model for professional production. Marey launched publicly in July 2025. A first-party public API is announced but currently waitlist-only; developers can run Marey today through inference partners fal.ai and ComfyUI. Backed by Bessemer Venture Partners and General Catalyst.

Moonvalley is profiled on the APIs.io network. Tagged areas include Company, Ai Ml, Generative AI, Video Generation, and Video.

Moonvalley’s developer surface includes engineering blog, support, signup flow, and 6 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/moonvalley: open an issue to ask a question, or submit a pull request to add artifacts.
