  Bloomberg ships one first-party command-line utility alongside the BLPAPI SDK: the Schema
  Downloader. It is a standalone tool that downloads the service schemas a BLPAPI session would
  negotiate at runtime, so those schemas can be replayed offline against the SDK's TestUtil
  component to build and assert messages without a live Bloomberg connection. There is no
  general-purpose Bloomberg API CLI — data retrieval is done through the BLPAPI SDK bindings or
  the Data License REST API, not from a shell.

      (Thu, 16 May 2024 12:37:04 GMT) — the tool has not been re-released in over two years while
      the BLPAPI SDK it supports moved to 3.26.7.1 in August 2026. The command/flag surface is NOT
      published on any public page; it ships inside the archive, so `commands` is deliberately
      empty rather than guessed.
