Openlayer

Openlayer is an AI evaluation, testing, and observability platform for machine learning and LLM applications. Its REST API lets teams create projects, commit model versions and datasets, run tests, stream production inference data into monitoring pipelines, and retrieve test results - with official SDKs generated from a Stainless OpenAPI definition.

Openlayer publishes 6 APIs on the APIs.io network, including Commits API, Data Stream API, Inference Pipelines API, and 3 more. Tagged areas include Artificial Intelligence, Evaluation, Testing, Observability, and LLM.

Openlayer’s developer surface includes authentication, documentation, engineering blog, and 9 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/openlayer: open an issue to ask a question, or submit a pull request to add artifacts.
