FAQ
Options data FAQ
More in the options docs, or email [email protected].
What is the options symbol format?
O: + underlying + expiration (YYMMDD) + C/P + strike × 1000 padded to 8 digits. For example, O:QQQ261016C00600000 is the QQQ 600 call expiring 2026-10-16.
Which endpoint returns Greeks and implied volatility?
The chain snapshot /v3/snapshot/options/{underlying}. Every contract includes greeks (delta, gamma, theta, vega), implied_volatility and open_interest, and you can filter by expiration, strike and call/put.
How far back does options history go?
More than 5 years. To find expired contracts, add expired=true to the contracts endpoint.
Do I need a stocks plan to buy options data?
No. The Options plan works on its own. If you also have a stocks plan, both share one API key and their daily calls and monthly traffic add up.
Can I pull option chains with Python?
Yes. Call the REST endpoints with requests, or use polygon-api-client with base set to our URL. The docs include complete examples.
