Cleanlab

Cleanlab is a data-and-AI trust platform. Its Trustworthy Language Model (TLM) wraps any LLM with a real-time trustworthiness score to catch hallucinations, Cleanlab Studio curates and labels training data and deploys reliable ML models, and Codex adds a safety, guardrail, and remediation layer for AI assistants and RAG. The open-source cleanlab library underpins it all with data-centric AI.

Cleanlab publishes 3 APIs on the APIs.io network: Codex API, Studio API, and TLM API. Tagged areas include Artificial Intelligence, LLM, Trustworthiness, Data Quality, and Guardrails.

The Cleanlab catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Cleanlab’s developer surface includes authentication, documentation, engineering blog, and 10 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/cleanlab: open an issue to ask a question, or submit a pull request to add artifacts.
