agent402.tools

Option chain for a US-listed ticker: all listed expiration dates, the strike ladder, and per-contract bid/ask/last/volume/open-interest/implied-volatility for calls and puts at one expiry (nearest by default, or pass `expiration` as YYYY-MM-DD). Backed by Yahoo Finance's options endpoint with the session-crumb handshake handled server-side.
