I have a few questions I hope somebody could clarify for me.

  • Is it possible to add the 0x API to a digital crypto wallet? if so what is the requirement for the underlying system?
  • Does it cost anything or can I monetize it myself? (earning a fee from people using the system within the wallet)

Sincerely Frederik

It is completely free to integrate with 0x API, you can do it by simply making a request to our hosted 0x API service when the user is looking to swap tokens.

We allow for specifying optional buyTokenPercentageFee and feeRecipient parameters so you can easily monetize to whatever extent you'd like.

For more information see the 0x API docs
