Smol Machines

Smol Machines (smol machines, inc.) is a Y Combinator-backed developer infrastructure company building portable, self-contained Linux microVMs. Its open-source `smolvm` engine and `smol` CLI (both Rust, Apache-2.0) boot hardware-isolated virtual machines from any OCI image in under 200ms — on a laptop, in the smolfleet cloud, or self-hosted — with no daemon and no Docker. The same Machine API runs locally as an in-process microVM or against the hosted smolfleet control plane at api.smolmachines.com, so teams sandbox untrusted code and AI-agent workloads, ship stateful `.smolmachine` artifacts, and deploy machines across a cluster without changing a line. Node and Python SDKs (`smolmachines`), a local REST API, and a cloud REST API are all public.

Smol Machines publishes 19 API contracts indexed on the APIs.io network, including Apps API, Billing API, Containers API, and 16 more. Tagged areas include Company, MicroVM, Sandbox, Virtualization, and Developer Tools.

The Smol Machines catalog on APIs.io includes 1 Spectral governance ruleset.

Smol Machines’ developer surface includes authentication, documentation, API reference, getting-started guide, quickstart, signup flow, pricing, and 29 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/.

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

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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)
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)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

9 more unmet checks in the Agent Readiness table above.

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

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/smol-machines/apis.yml: open an issue on github.com/api-evangelist/smol-machines to ask a question or point us at an artifact you publish.
