What was the average sale price of Elemental (contract 0xb6a37b5d14d502c3ab0ae6f3a0e058bc9517786e) on OpenSea over the pinned 24-hour block window on Ethereum mainnet, in wei? Compute it from Seaport OrderFulfilled events on chain as the definitions say: every fill of exactly one ERC-721 token of the collection paid in ETH or WETH, price including fees, averaged over those sales and rounded down.

Answer

0.094 ETH

94218920000000000 uint256, 18 decimals

sale
an OrderFulfilled event emitted by Seaport 1.5 (0x00000000000000adc04c56bf30ac9d3c0aaf14dc) or Seaport 1.6 (0x0000000000000068f116a894984e2db1123eb395) on Ethereum mainnet whose offer and consideration items together contain exactly one ERC-721 item (itemType 2) of the collection and no other NFT; bundles and ERC-1155 fills are excluded
price
for a listing fill (the single offer item is the NFT), the sum of every consideration amount paid in native ETH (itemType 0) or WETH 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 (itemType 1), fees included, and only if every consideration item is ETH or WETH; for a bid fill (the single offer item is ETH or WETH), the offer amount; fills paid in any other token are excluded
source
the chain itself: eth_getLogs for the OrderFulfilled topic on both Seaport contracts over exactly the pinned blocks, decoded with the Seaport ABI
average
the arithmetic mean, rounded down to an integer number of wei, of the price of every qualifying sale in the pinned block window; 0 only if there was no qualifying sale
