Hyperliquid

Hyperliquid is a high-performance Layer 1 blockchain (HyperBFT consensus, HyperCore + HyperEVM execution) best known for its native perpetual futures and spot DEX with capacity for hundreds of thousands of orders per second. Developers and traders interact with Hyperliquid through a public REST and WebSocket API at api.hyperliquid.xyz for trading, order management, market data, and account state. Official Python and Rust SDKs wrap the API, and the node, order-book server, and HyperEVM tooling are open-sourced under the hyperliquid-dex GitHub organization.

Hyperliquid publishes 2 APIs on the APIs.io network: WebSocket API and Info API. Tagged areas include DeFi, Perpetuals, DEX, Layer 1, and Trading.

The Hyperliquid catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Hyperliquid’s developer surface includes documentation, GitHub presence, 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.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% 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/hyperliquid: open an issue to ask a question, or submit a pull request to add artifacts.
