"21 is free software that implements the Payment Required HTTP status code and much more besides. It makes it easy to (a) send and receive micropayments over HTTP and to (b) write new kinds of programs that use this basic technology as an intrinsic primitive, like machine-payable APIs and intelligent agents."
