Before start

The Open API is currently in beta, and more endpoints will be added. The rate limits and request and response data types may change, and maintenance could be scheduled at any time before the API goes official release. In that case, we will post notifications in the announcement channel in our Developer Hub in advance.

X2Y2 provides Open APIs and Javascript SDK to help developers building strong web3 applications like analytics tools and trading bots.

The Open API and Javascript SDK provides different abilities, and we suggest you use both at the same time.

Open API

The Open APIs aim to provide real-time data including

  • Orders(listings)
  • Events
