For e-commerce, CityPay.io provides an API integration and a dedicated WooCommerce plugin that let online stores accept cryptocurrency at checkout. The API connects a website’s billing flow to the CityPay.io gateway, while the plugin offers a lower-code path for WooCommerce shops.

This is aimed at online merchants who want to add crypto as a payment option without building gateway infrastructure themselves.

What's good

  • Ready-made WooCommerce plugin
  • Flexible API for custom integrations

Trade-offs

  • Requires technical setup for API path
  • Limited to supported cryptocurrencies
