Moondream

Moondream is a fast, efficient open vision language model (VLM) from M87 Labs. The Moondream Cloud API turns images into structured output through five Skills — Query (visual question answering), Caption, Detect (bounding boxes), Point (center coordinates), and Segment (SVG path masks) — plus an OpenAI-compatible chat endpoint, an asynchronous Batch API, and cloud finetuning (Lens). Model weights are open and downloadable from Hugging Face; hosted inference is pay-per-token with HIPAA and SOC 2 available. Official Python and Node.js SDKs are published.

Moondream publishes 2 APIs on the APIs.io network: OpenAI Compatibility API and Skills API. Tagged areas include Company, Artificial Intelligence, Machine-Learning, Computer-Vision, and Vision Language Model.

Moondream’s developer surface includes authentication, changelog, documentation, API reference, getting-started guide, engineering blog, pricing, and 23 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/moondream: open an issue to ask a question, or submit a pull request to add artifacts.
