Netflix doesn't appear to have an official Fast.com cli client. A quick search yielded three cli libraries:

• https://github.com/banteg/fast
• https://github.com/gesquive/fast-cli
  • Seem stale, not under current development
• https://github.com/sindresorhus/fast-cli
  • Nodejs library, commits within the last 6 months, latest release in May 2021
