How to Obtain the Listings (Total # of Sellers) for a Card?

I’m trying to track the number of sellers that are listing a specific card, alongside the lowest/market price of said card. Say I’m looking at Currently, it says there are a total of 86 listings/results (for the Near Mint condition). That’s the number I’m looking to capture.

Is there any GET command I can use to get this value? Or at least one for every condition, with some way to filter it by condition to get each quantity?
