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
  • Offers
  • Contracts info and stats

Javascript SDK

Place orders, make offers, and commit purchase.

SDK Repository


Can I create listings through the API?

You need to use the Javascript SDK with a valid API key to create and manage listings/offers, purchase NFTs.

How can I obtain an API Key?

You can request an API key at our Developer Hub.

Which endpoints require an API key

All endpoints need an API key at the moment, but we will make GET requests free of API keys when we're ready.

Can I contact X2Y2 about the API?

Yes. You can request an API key or post related questions on our Developer Hub on Discord.
