Payment Required

Reserved for future use. The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, as proposed, for example, by GNU Taler,[33] but that has not yet happened, and this code is not widely used. Google Developers API uses this status if a particular developer has exceeded the daily limit on requests.[34] Sipgate uses this code if an account does not have sufficient funds to start a call.[35] Shopify uses this code when the store has not paid their fees and is temporarily disabled.[36] Stripe uses this code for failed payments where parameters were correct, for example blocked fraudulent payments.[37]
