Option chain API FAQ
What is 期权链 API?
An API that returns the full option chain for an underlying: strikes, expirations, quotes, OI, IV, and Greeks.
Can I get historical option chains?
Yes. Pass date=YYYY-MM-DD or omit date for the latest available session.
Is the full chain available over WebSocket?
No. Full chains are REST-only. WebSocket is for trade flow, not whole-chain snapshots.
