Unto Labs

Unto Labs is the team behind Thru, a high-performance Layer 1 blockchain for ultra-low-latency, ultra-high-throughput applications, built around ThruVM — a novel virtual machine targeting the RISC-V architecture so programs are written in plain C rather than crypto-specific languages. Founded in late 2024 by Jump Crypto / Solana alums and backed by Framework Ventures and Electric Capital, Unto Labs publishes a public gRPC and gRPC-Web API on the Thru Alphanet, protobuf definitions, C/Rust/TypeScript SDKs, a first-party CLI, a hosted Explorer MCP server for AI agents, llms.txt documentation sets, and installable agent skills.

Unto Labs is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Cryptocurrency, Blockchain, Layer 1, and RISC-V.

Unto Labs’ developer surface includes documentation, getting-started guide, support, changelog, CLI, authentication, sandbox, and 19 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):

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)
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

8 more unmet checks in the Agent Readiness table above.

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

Access Clarity scores 0.0 — up to +20.0 composite points
Contract Quality scores 24.0 — up to +19.0 composite points
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/unto-labs/apis.yml: open an issue on github.com/api-evangelist/unto-labs to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Semiconductor Consortia (RISC-V, OCP hardware, CHIPS awards)	undeclared	-	-	-
Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 3

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

gRPC

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified

RISC-V
