All the options returned will be for that expiry only. You can select a stock options quotes api expiry easily enough though:.

I find it best to call the previous URL to get the list of valid expiry stock options quotes api, then use this one to get all the strikes for a specific expiry date.
Unfortunately they are not. If you look at the sample pasted above you will notice both the name and value should be enclosed in quotes but are not.

The OptionPair objects stock options quotes api created and displayed in the grid.
