    abstract =  {This document defines the "Payment" HTTP authentication scheme, enabling HTTP resources to require a payment challenge to be fulfilled before access. The scheme extends HTTP Authentication, using the HTTP 402 "Payment Required" status code. The protocol is payment-method agnostic, supporting any payment network or currency through registered payment method identifiers. Specific payment methods are defined in separate payment method specifications.},
