Shipyard Software

Shipyard Software is the DeFi technology company behind Clipper, a decentralized exchange (DEX) designed for retail traders that offers blue-chip token swaps with no impermanent loss for liquidity providers. Founded in 2021 by Mark Lurie and backed by Polychain and others, Shipyard built market-making technology across eight blockchains before being acquired by Sushi Labs in January 2025. Clipper, now governed by AdmiralDAO, exposes a Request-for-Quote (RFQ) swap API for DEX aggregators and a Graph-hosted GraphQL subgraph for querying on-chain pool data.

Shipyard Software publishes 2 APIs on the APIs.io network. Tagged areas include Company, DeFi, DEX, Decentralized Exchange, and Cryptocurrency.

Shipyard Software’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, authentication, and 12 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 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.

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/.

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/shipyard-software: open an issue to ask a question, or submit a pull request to add artifacts.
