Getting Started

1. Create a 0x Account​

To create an account on the 0x Dashboard, click Sign Up, enter your name, email address and password, and click Continue

2. Create a Team​

Once verified, you'll be prompted to create a team on 0x. Decide on a team name and select the type of project you are building. You can share this account with your teammates.

3. Tour the Dashboard​

3.1 Test API Key​

Once you've created a team, you'll be taken to the 0x Dashboard where you can create and manage live API keys, find build resources, and raise support requests.

To find a list of all networks supported by 0x, check out the 0x Cheat Sheet.

Your dashboard comes with a Test API key you can use to make sample requests. Give it a try by plugging it into the curl request and running that from your CLI to see a live Swap API quote request: 

// Replace the API key in the header with your sample key
curl --location --request GET 'https://api.0x.org/swap/v1/quote?buyToken=DAI&sellToken=ETH&sellAmount=100000&excludedSources=Kyber' --header '0x-api-key: [api-key]'

3.2 Create an App​

Click Create an app to get a live API key that has access to multiple 0x products.


From the pop-up, enter your app's name and which 0x products (Swap API, Orderbook API) should be enabled for this API key, then click Continue.

Note: You will still be able to update the 0x products this key can unlock even after the app has been created.

3.3 Add 0x Explorer Tag​

In the next screen, you can add a unique tag that can be used to identify transaction data from your app on 0x Explorer. You may use the same tag for all your apps, or create a separate one for each.

0x Explorer provides data about ERC-20 transactions routed through 0x API. It’s a reliable and transparent tool to help developers and users verify transactions and analyze on-chain activity in an easy and low-friction way.

Learn more about 0x Explorer Tags.

You can skip for now and add a tag later.

3.4 Reveal Your API Key​

On the final screen, copy your API key! This key is unique and tied to your app. Do not share it. You can also create additional API keys for the app if you need them.

Your API keys will allow you to authenticate requests on 0x. Remembmer to specify the key in your requests vai the 0x-api-key header parameter:
