Saber

Saber is a decentralized automated market maker (AMM) on the Solana blockchain, optimized for trading and providing liquidity between mean-reverting assets such as stablecoins and wrapped or pegged tokens. Its StableSwap program delivers low-slippage swaps and capital-efficient liquidity pools. Saber does not expose a REST/HTTP API; developers integrate through its on-chain StableSwap program using first-party TypeScript SDKs (the @saberhq/* packages on npm) and Rust crates (crates.io) that construct and submit Solana transactions. The project also maintains open-source Solana tooling, an asset/pool registry, and on-chain governance. Saber was surfaced as a portfolio company of Multicoin Capital.

human only

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.

Kin Score

API Evangelist profiles Saber 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 — Saber scores 12.2/100 (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 Saber

Each block below is one kind of artifact we hold for Saber. 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.
