This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Liquid (liquid.trade, formerly tryliquid.xyz) is a perpetual-futures trading platform and perp-DEX aggregator. Traders go long or short on 500+ markets — crypto perps, US and international equities, commodities, FX, indices, pre-IPO names like OpenAI, Anthropic and SpaceX, and event/prediction contracts — 24/7 with up to 50x multipliers, routed through venues including Hyperliquid, with funds held in the user's own non-custodial wallet.
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 no public REST API and no OpenAPI. Its entire programmable surface is Co-Invest,
a published remote MCP server at https://coinvest.liquid.trade/mcp that puts market research,
portfolio state and confirmed trade execution inside Claude, ChatGPT, Cursor, iMessage and any
MCP-compatible client.
- OAuth 2.1 — authorization code + PKCE (S256) + dynamic client registration, with RFC 8414 and RFC 9728 discovery documents live on the MCP host.
- Two scopes:
readandtrade. The grant can never withdraw funds or change account settings. - Every state-changing action renders a confirmation card; nothing executes without a human tap.
- Paper mode: a simulated $10,000 balance against live market data.
