Probabl

Probabl (styled ":probabl.") is the French, Inria-spun-out company behind scikit-learn — "the Tabular AI company by the creators of scikit-learn" — founded in 2023 to develop, maintain and commercially sustain the open-source Python data-science stack (scikit-learn, skrub, skore). Its commercial product is Skore: an open-source Python library (`skore`) that turns model training into structured, auditable artifacts — estimator reports, cross-validation reports, comparison reports, data and metric diagnostics — plus Skore Hub, a hosted collaboration platform where teams push, compare and track those artifacts across workspaces and projects. Skore Hub exposes a public REST API (Skore Hub, OpenAPI 3.1.0, 67 operations) covering identity/OAuth, workspaces, members and API keys, projects, estimator/cross-validation/comparison reports, artifacts, project goals, and OpenAI/Anthropic-compatible agent endpoints. Probabl also publishes a first-party Agent Skills package (probabl-skills, BSD-3-Clause) of 14 data-science skills for coding agents such as Claude Code and Cursor, a `skore` CLI, training via Skolar, and the Scikit-learn Central ecosystem explorer.

Probabl publishes 8 APIs on the APIs.io network, including Anthropic Compatible Agent API, Health API, Identity API, and 5 more. Tagged areas include Company, Open-Source, Machine-Learning, Data Science, and scikit-learn.

Probabl’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, changelog, CLI, and 15 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/probabl: open an issue to ask a question, or submit a pull request to add artifacts.
