Fluidstack
Fluidstack is an AI cloud platform that builds and operates high-performance, single-tenant GPU clusters for top AI labs, governments, and enterprises. Founded in 2017 out of Oxford University and now headquartered in New York City, Fluidstack manages more than 100,000 GPUs across its global network and has been selected by customers including Anthropic, Meta, Mistral, Poolside, Black Forest Labs, and Character.AI. Its core offering combines on-demand bare-metal GPU clusters (including thousands of NVIDIA H200s with InfiniBand) with managed Kubernetes and managed Slurm orchestration layers, Lighthouse observability, and human-on-call site reliability. Fluidstack exposes a global REST Management API (api.atlas.fluidstack.io/api/v1alpha1) and the fluidctl CLI for managing organizations, projects, regions, clusters, instances, members, invitations, and SSH keys. The platform is GDPR, SOC 2 Type 2, and ISO 27001 certified, and was awarded ClusterMAX Gold by SemiAnalysis.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Fluidstack the way a machine reads it — 25 machine-readable artifacts across 7 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Fluidstack scores 33.2/100 (thin), with a separate agent-readiness read of 41/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Fluidstack
Each block below is one kind of artifact we hold for Fluidstack. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 7
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
