Liquid

Liquid (liquid.trade, formerly tryliquid.xyz) is a perpetual-futures trading platform and perp-DEX aggregator that lets retail traders go long or short on 500+ markets — crypto perps, US and international equities, commodities, FX, indices, pre-IPO names such as OpenAI, Anthropic and SpaceX, and event/prediction contracts — 24/7 with up to 50x multipliers, routing orders through venues including Hyperliquid while keeping funds in the user's own non-custodial wallet. Its programmable surface is Co-Invest, a published remote Model Context Protocol (MCP) server at coinvest.liquid.trade that puts market research, portfolio state and confirmed trade execution inside Claude, ChatGPT, Cursor and any MCP-compatible client, secured with OAuth 2.1 (PKCE + dynamic client registration) and two scopes, read and trade. Liquid raised an $18M Series Seed led by Neo and Left Lane Capital in April 2026, following a $7.6M seed led by Paradigm.

Liquid publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto Defi, Trading, Perpetual Futures, and Prediction Markets.

Liquid’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, pricing, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), 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/liquid: open an issue to ask a question, or submit a pull request to add artifacts.

  name: Liquid Co-Invest MCP
  description: Co-Invest is Liquid delivered as a remote Model Context Protocol (MCP) server. Once connected, an MCP client
    can research markets (live prices, funding rates, open interest, whale positioning, liquidation maps, news, leaderboards,
    prediction markets), read the connected account's portfolio, orders and balances, and propose real trades on the user's
    Liquid account. Every state-changing action renders a confirmation card that the human must tap before an order is sent.
    Authorization is OAuth 2.1 with PKCE and dynamic client registration, scoped read and trade; the connection can never
    withdraw or transfer funds. A paper-trading mode runs a simulated $10,000 balance against live market data.
