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 API contracts indexed on the APIs.io network: Protocol API, Tokens API, and Whirlpools API. Tagged areas include Company, Defi Dex, DeFi, Decentralized Exchange, and Solana.

The Orca catalog on APIs.io includes 1 Spectral governance ruleset.

Orca’s developer surface includes documentation, API reference, getting-started guide, support, authentication, sandbox, changelog, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
