# Overview

> API reference for the MoonPay widget integration.

The MoonPay widget integration is powered by two APIs:

* **Ramps**: buy and sell quotes; transaction lookups; supported
  countries, currencies, and payment methods.
* **Virtual Accounts**: programmatic on-ramp and off-ramp via virtual
  bank accounts, plus the associated transaction history.
