Decart

Decart is an AI research lab and API platform building real-time world models — foundation models that generate and transform video frame-by-frame as they are watched. Its Decart API Platform (platform.decart.ai) exposes the Lucy family of realtime and batch video/image models plus the Oasis promptable world model through three surfaces: a Realtime API that edits a live WebRTC camera or video stream with text prompts and reference images, a Queue API that submits asynchronous video jobs and polls them to completion, and a Process API for synchronous image editing. The platform ships first-party JavaScript, Python, Swift and Android SDKs, ephemeral client tokens for browser and mobile apps, a Files API for reusable reference images, and a gRPC action-to-video session protocol for Oasis 3 Preview. Pricing is pay-as-you-go and metered per generated second (video and realtime) or per generation (images).

Decart publishes 9 APIs on the APIs.io network, including Realtime API, Client API, Files API, and 6 more. Tagged areas include Artificial Intelligence, Machine-Learning, Video, Video Generation, and Video Editing.

Decart’s developer surface includes documentation, API reference, getting-started guide, quickstart, engineering blog, support, pricing, and 36 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/decart: open an issue to ask a question, or submit a pull request to add artifacts.
