big xyt
big xyt AG (now branded simply xyt, with big-xyt.com redirecting to xyt.one) is an independent, majority employee-owned market data analytics firm headquartered in Frankfurt am Main, Germany. It sells tick-data-driven market intelligence covering equities, ETFs, listed derivatives, FX, and fixed income across 120+ venues, processing 12bn+ messages per day with roughly ten years of history at nanosecond precision and market-by-order granularity. Products include the Liquidity Cockpit (market share and liquidity analytics), Transaction Cost Analysis against its SMART benchmark, pre-trade cost modeling, a Datashop of analysis-ready datasets and APIs, and an xyt AI natural-language query layer. Three API products are publicly named - the big xyt API, Liquidity Cockpit API, and TCA API - but their reference documentation sits behind a login at docs.big-xyt.com (HTTP 403 unauthenticated), and access is sales-gated via a book-a-demo motion with no self-serve signup, public pricing, or public OpenAPI.
big xyt publishes 3 APIs on the APIs.io network. Tagged areas include Financial, Market Data, Tick Data, Trading, and Analytics.
big xyt’s developer surface includes authentication, developer portal, documentation, engineering blog, support, and 7 more developer resources.
