Get Started

Set up an account on the 0x Dashboard to generate API keys, manage your apps, tap into more developer resources.

Follow these steps to get started, in less than 5 minutes!

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:

// Sell 100000 WETH for DAI
// Replace the API key in the header with your sample key

curl --request GET \
  --url 'https://api.0x.org/swap/permit2/quote?sellAmount=100000000000000000000000&taker=0xa423C7Be031E988B25fb7Ec39b7906582f6858c6&chainId=1&sellToken=0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2&buyToken=0x6b175474e89094c44da98b954eedeac495271d0f' \
  --header '0x-api-key: YOUR_API_KEY'
  --header '0x-version: v2'

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 and Gasless API) should be enabled for this API key, then click Continue.

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

3.3 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. Remember to specify the key in your requests via the 0x-api-key header parameter:



// Sell 100000 WETH for DAI
// Replace the API key in the header with your sample key

curl --request GET \
  --url 'https://api.0x.org/swap/permit2/quote?sellAmount=100000000000000000000000&taker=0xa423C7Be031E988B25fb7Ec39b7906582f6858c6&chainId=1&sellToken=0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2&buyToken=0x6b175474e89094c44da98b954eedeac495271d0f' \
  --header '0x-api-key: YOUR_API_KEY'
  --header '0x-version: v2'
