cash-cli

A command‑line utility lets users convert monetary amounts between currencies directly from a terminal session. By supplying an amount and two currency codes, the tool queries an online exchange‑rate service and returns the converted value. Users can also set a default source and target currency for repeated use.

The program supports several public APIs, including Exchange Rates API as Fixer, Currency Layer, and Open Exchange Rates, and it caches results to reduce unnecessary network calls. Configuration options allow selection of the API source and saving of preferred currency pairs.

It is distributed as a Node.js package and can be installed globally via npm or through Homebrew on macOS. The software is released under the MIT license and is marked as stable for production use.
