Snorkel AI

Snorkel AI is a data-development / AI data platform built on the open-source Snorkel weak-supervision library. The enterprise Snorkel Flow platform supports programmatic labeling, data curation, model training, and evaluation, and is driven programmatically through a Python SDK that targets a per-instance REST API rather than a single public hosted endpoint. Snorkel also delivers Expert Data-as-a-Service for frontier-model training and evaluation data.

Snorkel AI publishes 4 APIs on the APIs.io network, including Snorkel Flow SDK / Platform, Programmatic Labeling, Evaluation, and 1 more. Tagged areas include Artificial Intelligence, Data Development, Programmatic Labeling, Weak Supervision, and Evaluation.

Snorkel AI’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.

scored 2026-10-04 · rubric v0.23.0
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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/snorkel-ai: open an issue to ask a question, or submit a pull request to add artifacts.
