How can I monetize my app with 0x API?

0x offers two options for monetizing your order flow so you can build a sustainable Web3 business. On all of our plans, you can set a percentage fee and a fee recipient on trades initiated within your application via Swap API requests. Additionally, you may take a percentage of the positive slippage generated from your swaps. You can find details on both approaches in our API references.

For more specific information, please refer to how to monetize your app with 0x in our documentation.

I’ve just signed up. When do I pay my first bill?

You will pay the plan subscription fee once you input your payment information. You will be billed for any overages at the end of the month.

Do you offer discounts?

Yes, you can sign up for our yearly plans to receive a 20% discount on the subscription fee!

I already had several apps before you rolled out paid plans. Will I be charged for those apps?

As long as you remain on the free plan, we will not charge you any subscription fees. However, please note that we will disable apps that exceed your limit. Please let us know which of these apps we can delete to ensure you remain within the terms of the free plan by contacting 0x Developer Support via the 0x Developer Dashboard.

Do I get billed for my Demo App?

Each 0x Dashboard account includes a Demo App with API keys, enabling you to test your integration. Your demo app has a rate limit of 20 RPM, which should be sufficient for your testing needs. You will not be billed for any requests made with keys from your demo app.
