These selling limits restrict the new seller to a maximum quantity of items per month or to a maximum value of items listed per month. You can check your current selling limits either through Selling Manager Pro or through GetMyeBaySelling API call (some eBay sites do not support this).
GetMyeBaySelling returns the remaining quantity of items that the seller can sell, and the remaining value amount, via theSummary.AmountLimitRemaining and Summary.QuantityLimitRemaining elements. You need to set SellingSummary.Include to true in the request.
