Machine0

Machine0 is a Y Combinator (S26)-backed infrastructure company, operated by Fundamental Software, that provides persistent, on-demand cloud virtual machines driven entirely from the command line and optimized for AI agents. The machine0 CLI ("Cloud VMs from the CLI") and a remote Model Context Protocol (MCP) server let you create, provision, snapshot, suspend and SSH into dedicated VMs — NixOS or Ubuntu, up to 60 vCPU / 240GB RAM with optional GPUs — across five regions (US East/West, UK, EU, Asia) with static IPs, HTTPS endpoints and per-minute billing. Suspend a VM to freeze its state and stop compute charges. Every CLI command supports JSON output and the MCP server exposes the same machine, image, SSH-key and remote-exec operations to agents.

Machine0 is listed with 1 API on the APIs.io network. Tagged areas include Company, Cloud, Infrastructure, Virtual Machines, and AI Agents.

Machine0’s developer surface includes documentation, quickstart, pricing, changelog, CLI, and 11 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

7 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Governance scores 4.5 — up to +11.5 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/machine0/apis.yml: open an issue on github.com/api-evangelist/machine0 to ask a question or point us at an artifact you publish.
