CentML

CentML is an AI inference optimization platform that serves popular open models through OpenAI-compatible serverless endpoints and lets teams stand up dedicated, autoscaling model-serving deployments and compute clusters. The serverless inference API runs at https://api.centml.com/openai/v1 with Bearer API keys, while a separate platform (control-plane) API manages deployments and clusters.

CentML publishes 5 API contracts indexed on the APIs.io network, including Clusters API, Completions API, Deployments API, and 2 more. Tagged areas include Artificial Intelligence, LLM, Inference, Serverless, and GPU.

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

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

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
