Now available: NFT collection trading volume

Center now provides best-in-class collection trading volumes.

We are pleased to announce that the Center API now provides best-in-class NFT collection trading volume.

What makes our market data best-in-class?

  • Pristine accuracy: We have the best indexer on the market, which means we never miss a transaction.
  • No caching: We do not cache any of our data – that means we reflect new sales immediately after we see them on chain.
  • Variety of currencies: We provide all of the data to our users, exactly as we see it on chain. This means you will get the full range of currencies that we see – ETH, WETH, USDC, and more. We let you decide how you want to aggregate it.

How do I use it?

Check out our brand new collection volume endpoint in our docs .

We currently support market data on Ethereum-mainnet from opensea and blur. We'll be adding additional chains and marketplaces soon.

Wen floor price?

Over the next several weeks, we will be rolling out new endpoints as we build a best-in-class market data suite. Stay tuned for floor prices.

We will also be adding more features to our trading volume endpoint:

  • Marketplace breakdowns: We will let you break out trading volume by marketplace. Want to see how the volume on Blur compares to OpenSea? With our API, it will be easy.
  • Custom, granular timeframes: We will let you precisely determine the timeframes that you care about. Our standard response provides trading volume over a common set of timeframes (6h, 24h, 7d, 30d). If that's not good enough, you'll be able to specify a custom timeframe. This includes historical timeframes – if you care about trading volume in June 2022 specifically, we can provide it.
