Lightly

Lightly is a data-curation and active-learning platform for computer vision. The LightlyOne platform exposes a REST API at https://api.lightly.ai for managing datasets, samples, embeddings, cloud datasources, selection / active-learning runs (the LightlyOne Worker), tags, and jobs. Lightly also maintains the open-source lightly self-supervised learning SDK, plus LightlyTrain and LightlyEdge products.

Lightly publishes 7 APIs on the APIs.io network, including Datasets API, Datasources API, Embeddings API, and 4 more. Tagged areas include Artificial Intelligence, Computer-Vision, Data Curation, Active Learning, and Embeddings.

Lightly’s developer surface includes authentication, documentation, engineering blog, and 8 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/lightly-ai: open an issue to ask a question, or submit a pull request to add artifacts.
