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.

Saber is profiled on the APIs.io network. Tagged areas include Company, Crypto Web3, Solana, Decentralized Finance, and Stablecoins.

Saber’s developer surface includes documentation and 7 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/saber: open an issue to ask a question, or submit a pull request to add artifacts.
