Get started in less than five minutes! To get started, simply create an account on the 0x Dashboard, choose a plan, set up your app, and generate your API keys. Here’s a step-by-step guide.

An app is a self-contained unit for each individual application that you’re building. Each app can have its own unique API keys and configurations.

You can monitor the API usage for your apps on the 0x Dashboard.

0x takes an on-chain fee on swaps involving a select few token pairs for the Free and Starter tiers. This fee is charged on-chain to the users of your app during the transaction. If you are on the Growth tier, we completely waive this fee for your customers.

The list of tokens eligible for fees evolves over time and is subject to change. The eligibility of tokens is determined by a number of factors including compliance obligations, market liquidity, and other strategic considerations. Fees will be detailed in each API response when applicable.

0x offers two options for monetizing your order flow so you can build a sustainable Web3 business. On all 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.‍

We offer a range of plans to suit various needs. If you are an individual or small team starting out, our Free plan is powerful enough to support you in building swap applications. The Starter plan is the most popular among teams as it is affordable and offers higher throughput as your user base and transactions grow. For larger companies, the Growth plan is perfect and comes with a 0% swap fee, enabling you to offer more competitive prices to your users. You can get started with them here.
