What it returns

One NFT collection's floor price, trailing 24h traded volume and market cap, one point a day over the last 1 to 365 days, oldest first, each in USD and in the chain's native coin (ETH on ETH and BASE, BNB on BNB). Each volume is the 24h volume as of that instant, not a period total. A collection that is not tracked returns 404.
