21: Build the Machine-Payable Web Build Status

21 logo

21 is an open source Python library and command line interface for quickly building machine-payable web services. It allows you to accomplish three major tasks:

  • Get bitcoin on any device
  • Add bitcoin micropayments to any Django or Flask app
  • Earn bitcoin on every HTTP request

The package includes:

  • an HD wallet to securely manage your bitcoin
  • crypto and bitcoin libraries to build bitcoin/blockchain applications
  • a micropayment-channels client and server
  • commands for mining, buying, and earning bitcoin, as well as requesting it from the 21 faucet
  • tools for publishing machine-payable endpoints to the 21 Marketplace
  • containers that allow your machine to sell machine resources for bitcoin

and much more.
