“0x has one of the most extensive and reliable DEX API services in the Web3 ecosystem, backed by a professional and responsive team. It's been a pleasure working with them to launch our DEX features on Coinbase Wallet.”

Sid Coelho-Prabhu

Director of Product at Coinbase

“We have been working with the 0x team for 3 years now and their APIs are a great choice for any builders out there looking for ultimate liquidity aggregation for their users. We definitely recommend looking into 0x as a simple, ready-made, plug and play solution.”

Nikola Jankovic

Founder at DeFi Saver

“We've been a proud 0x partner and community member for over 3 years. In order to help our users get the most efficient trading routes on Zerion, we knew we wanted to use their Swap API. It was easy to integrate and allowed us to offer users access to a wide range of liquidity sources on Ethereum and other EVM chains.”

Evgeny Yurtaev

Co-founder & CEO at Zerion

“Using Swap API was a no brainer for us. As a startup, being able to tap into 100+ exchanges with a single API integration saved us a lot of time that we can now spend focused in other areas of our product and our users. We are also excited to partner with the 0x team given their expertise working with wallets and fintechs. The team is professional, reliable and experts in their field.”

Jean Meyer

CEO at Deblock

“With Swap API we never have to worry about new liquidity sources coming out and the infrastructure overhead of searching for the best trading routes. It’s also been super easy for us to launch trading in other chains thanks to Swap API being available in the major chains. 0x turnkey solutions have allowed us to focus on other areas of our product and make Zapper one of the most popular apps in Web3.”

Justin D’Errico

Lead Engineer at Zapper

How do I start?

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.

How can I monetize my app with 0x?

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

What is the 0x Swap fee?

On the standard plan, 0x earns a 0.15% fee on swaps involving select token pairs. This fee is charged on-chain to the users of your app during the transaction. For high volume teams or teams with unique business models, please contact us to discuss a custom plan.

Which tokens are eligible for 0x Swap fees?

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.

Which tier is right for me?

We offer two transparent, flexible tiers for Web3 businesses of all sizes. You can get started with them here. If you are a high volume app or have a unique business model, please contact us to discuss a custom plan.

What is the maximum throughput that you can support on the Custom plan?

As high as you need! Seriously. We currently support teams with millions of users worldwide that require over 100 RPS. Contact us and we will work with your team to ensure your requirements are met.

Can I use the APIs for fetching DEX prices without submitting trades?

The APIs are optimized for trading use cases, so you will hit limits on the standard plan if you request quotes without submitting trades consistently. If you need to fetch DEX prices specifically, please contact us to discuss supporting this use case.
