Yahoo Finance CLI
A powerful, fully-featured CLI for fetching comprehensive stock data from Yahoo Finance.
This skill uses the community-supported yahoo-finance2 package. It outputs pure JSON, making it extremely easy for Agents to parse, filter, and analyze the data.
Installation Status
The package is globally installed as yahoo-finance.
(Installed via npm install -g yahoo-finance2)
Critical: One Symbol Per Call
The CLI syntax is:
yahoo-finance <module> <symbol> [options_json]
The CLI accepts exactly one symbol per invocation. The second positional argument is always parsed as a JSON options object, not a second symbol. Passing multiple symbols (e.g. yahoo-finance quote AAPL MSFT) causes a validation error ("Expected an object").
