Option Chain Snapshot

Returns a snapshot of options contracts for one underlying equity: per-contract pricing context, Greeks, implied volatility, open interest, latest quote and trade (when your plan includes them), and underlying reference. Use it for chain overviews, comparing strikes and expirations, research, and strategy work.

For one contract by underlying + OCC ticker, use Contract snapshot instead.
