  Exegy publishes no first-party client libraries on any public package
  registry. The proprietary Exegy Client API (XCAPI) — C++, C#, and Java
  libraries for Linux and Windows — is distributed only to entitled customers
  through the gated Exegy Customer Portal, and the Metro platform's Subway
  socket API and Freeway algorithmic API are likewise customer-only. The
  GitHub org (github.com/exegy) contains a single public repo of brand logos,
  no SDKs or specs. The only public packages are unofficial community Rust
  bindings for XCAPI.
