Farmer RPC

This document provides a comprehensive reference to Chia's Farmer RPC API.

Note about Windows command escaping

This document will use Linux/MacOS RPC syntax. When running rpc commands on Windows, you'll need to escape all quotes with backslashes.

For example, here is a typical RPC command on Linux and MacOS:

chia rpc farmer get_reward_targets '{"search_for_private_key": false}'

To run the same command on Windows, you need to escape the quotes with backslashes. In other words, add a \ before each double quote, such that:

"search_for_private_key" becomes \"search_for_private_key\" etc
