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 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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.
