NexGen Cloud Clusters API

A cluster is a managed Kubernetes cluster on Hyperstack, control plane + worker nodes preconfigured for GPU workloads. Clusters are region-scoped and can attach data volumes via Container Storage Interface (CSI) drivers. Most workflows: deploy cluster → configure storage → deploy workload → autoscale workers.

NexGen Cloud Clusters API is one of 64 APIs that NexGen Cloud publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Cluster. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, authentication docs, and rate-limit docs.

This API exposes 17 operations across 11 paths, and defines 27 schemas. It is described by OpenAPI 3.2.0, at version 1.0.

Requests are made against a single base URL, https://infrahub-api.nexgencloud.com/v1.

Authentication & Security 2

NexGen Cloud Clusters API declares 2 security schemes for authenticating requests. An API key is passed in the header as Authorization (accessToken). An API key is passed in the header as api_key (apiKey). By default, every request must be authenticated.

  • accessToken — Bearer Token
  • apiKey — Send it as apikey in header

Where this information came from

This is an independent, third-party profile of NexGen Cloud Clusters API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
