Similarly to stocks, Alpaca offers two different data sources for options:

Source	Description
Indicative	Indicative Pricing Feed is a free derivative of the original OPRA feed: the quotes are not actual OPRA quotes, they’re just indicative derivatives. The trades are also derivatives and they’re delayed by 15 minutes.
OPRA (Options Price Reporting Authority)	OPRA is the consolidated BBO feed of OPRA. OPRA Plan defines the BBO as the highest bid and lowest offer for a series of options available in one or more of the options markets maintained by the parties. OPRA feed is only available to subscribed users.
