This API retrieves purchase quotes on behalf of authenticated eBay buyers. Purchase quotes can be retrieved through the purchaseQuotes query featuring multiple filter criteria, or the user can use the purchaseQuotesByIds or purchaseQuotesLineItemsByIds queries to retrieve purchase quotes based on distinct purchase quote IDs or item commitment IDs. There is also a mutation to request a purchase quote from a seller, where the seller groups multiple item commitments into one purchase quote that can be paid for with one payment.
