Blockstack built-in payment system

Hello there,
I am a big fan of blockstack and I have questions regarding the built-in payment system that the developer can use in his Dapp,

  1. is there any api or docs about that ?
  2. is blockstack good fit for micropayments ?

We currently do not have an API specifically for payments. Our current roadmap does not anticipate creating one any time soon. Blockstack applications can make use of any of the existing available APIs for payments:

Paypal and Stripe are also options.
