Stader Labs
Stader Labs is a non-custodial, smart-contract-driven liquid staking platform for Proof-of-Stake networks. It lets retail users, exchanges, and custodians stake crypto and receive tokenized liquid staking tokens (ETHx, MaticX, BNBx, NEARx and others) that stay usable across 40+ DeFi protocols while earning auto-compounding rewards, with no lock-up and no minimum stake. Stader operates as multi-chain middleware infrastructure across Ethereum, Polygon, BNB Chain, Hedera, Fantom, and NEAR, and its contracts have been audited by Sigma Prime, Halborn, Peckshield, Code4rena, and OtterSec. The project is on-chain and open source rather than a REST/OpenAPI provider; developer surface area is Solidity/Go/Rust smart contracts, node software, and CLI tooling on GitHub.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Stader Labs the way a machine reads it — 1 machine-readable artifact, 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 — Stader Labs scores 14.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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 Stader Labs
Each block below is one kind of artifact we hold for Stader Labs. 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.
Security Posture 1
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.
