yfinance

Overview

yfinance pulls public financial data from Yahoo Finance: revenue trend, margins, and analyst consensus for any company with a ticker. Public data, no paid key.

How PRISM uses it

PRISM uses yfinance as its public-financials muscle for public companies (the collect-financials.py path). Private companies use an estimate waterfall instead. Part of the right-tool-for-each-job doctrine. Note: it is the yfinance library reading public Yahoo data, not a Yahoo MCP.
