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 publishes 2 APIs on the APIs.io network. Tagged areas include Company, Crypto, 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.

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.

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 github.com/api-evangelist/unto-labs: open an issue to ask a question, or submit a pull request to add artifacts.
