This is a Javascript API to provide an easier way to check if the Secure Payment Confirmation[1] feature is available. Currently, the only way to determine SPC’s availability is to create a PaymentRequest with the required parameters[2], which is clunky and difficult in the case where a developer wants to check for SPC before starting to process a payment.
