big xyt API is one of 3 APIs that [big xyt](https://apis.io/providers/big-xyt/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Tick Data, Market Data, and Analytics. The published artifact set on APIs.io includes API documentation.

The core big xyt (xyt hub) API gives trading firms and exchanges programmatic access to normalised and raw tick data and analytics across 120+ venues without in-house tick data infrastructure. Publicly listed on the xythub.github.io landing page, but the reference documentation at docs.big-xyt.com is login-gated (HTTP 403 unauthenticated), so endpoints and base URLs are not publicly documented. Legacy public docs (2018, github.com/xythub) described an HTTPS REST service using OAuth 2.0 password-grant bearer tokens with Protocol Buffers payloads and official Python, R, Java, and C# client libraries.
