TCA API
Execution analytics API spanning basic Transaction Cost Analysis - benchmarking trades and orders for best execution, compliance, and client reporting - through full API access to quantitative modelling functions for exchanges and sell-side and buy-side analysts. Publicly named on the xythub.github.io landing page, but the API reference at docs.big-xyt.com is login-gated (HTTP 403 unauthenticated), so no endpoints or base URL are publicly documented.
