Nscale

Nscale is an AI/GPU cloud that pairs serverless, OpenAI-compatible inference with on-demand GPU compute. The Serverless Inference API serves open models (Llama, Qwen, DeepSeek, GPT OSS, Mistral, Flux) at https://inference.api.nscale.com/v1 with pay-per-token billing, while the platform API provisions GPU clusters, compute instances, networks, and storage.

Nscale publishes 5 APIs on the APIs.io network, including Chat API, Completions API, Embeddings API, and 2 more. Tagged areas include Artificial Intelligence, GPU, Inference, Serverless, and Cloud Compute.

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

Nscale’s developer surface includes authentication, engineering blog, documentation, and 7 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/nscale: open an issue to ask a question, or submit a pull request to add artifacts.
