Orca

Orca is the leading user-friendly concentrated-liquidity automated market maker (AMM) on Solana, built around Whirlpools. Liquidity providers concentrate capital within custom price ranges for higher capital efficiency, traders swap tokens with dynamic Adaptive Fees, and creators launch tokens and lock liquidity for launches. Developers and autonomous agents integrate via the open Whirlpools SDKs (TypeScript, Rust, and a Python option) and the read-only Orca Public REST API (api.orca.so) for pool, token, lock, and protocol-wide data.

Orca publishes 3 APIs on the APIs.io network: protocol API, tokens API, and whirlpools API. Tagged areas include Company, Defi Dex, DeFi, DEX, and Solana.

Orca’s developer surface includes documentation, API reference, getting-started guide, support, authentication, sandbox, changelog, and 18 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.
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/orca: open an issue to ask a question, or submit a pull request to add artifacts.
