The option chain for a stock, 15-minute delayed. Ask for the listed expirations, the calls-and-puts chain for one expiration (strike, greeks, implied volatility, open interest and the latest daily price), or a single contract by its OCC symbol. Bid and ask are shown only when your plan entitles live quotes; otherwise the last daily price and greeks stand in.

GetOptionChain
The calls-and-puts chain for one expiration: strike, type, last daily price, implied volatility, open interest and greeks (delta, gamma, theta, vega). Defaults to the nearest upcoming expiration; narrow with minStrike/maxStrike, type, and maxResults so the answer stays focused (a full chain can run to hundreds of contracts).
Parameters: ticker (required); expiration (yyyy-MM-dd, default nearest upcoming); minStrike / maxStrike; type (call / put); maxResults (default 60).
Ask: "Show NVDA calls and puts near the money for the September 18 2026 expiry."
