LOOKUP OPTIONS CONTRACTS & SPREADS
You can use our options prices API to lookup available options contracts for a given security:
This will list all current (non-expired) options contracts for the given security, in order of expiration date (latest to earliest). Note the expiration values - you will use these later to fetch prices for that specific options contract. To filter this list further, let's try adding an expiration parameter:
This will return all AAPL options contracts expiring on April 7th, 2017. You can also specify type=put or type=call to filter by contract type.
If you need to check which expiration dates are available to filter by, use this API:
