  "notes": "Verified scope: CoinGecko justin-aversano-twin-flames-collection-of-100-twin-portraits resolves to contract 0x3c28de567d1412b06f43b15e9f75129625fa6e8c (checked via api.coingecko.com/api/v3/nfts/{slug}), matching the brief. Closing hash for block 26035049 confirmed via eth_getBlockByNumber on ethereum-rpc.publicnode.com: 0xbd39338fa192476cc40b0bd068e92d368b8cdce9c91c3c90b174090f549082ee (timestamp 1790104535), matches the pin. OpenSea Events API (api.opensea.io/api/v2/events/collection/...) returned 401 Missing API Key; no credentials available, so discovery fell back to onchain Transfer logs and Blockscout's token-transfer index for the same address. eth_getLogs for Transfer(address,address,uint256) at this contract, scanned on 3 independent operators (rpc.mevblocker.io, 0xrpc.io/eth, rpc.flashbots.net), returned 0 logs for the full pinned window blocks 26027905-26035049, and 0 logs (rpc.flashbots.net, full success, no truncation) for the preceding 7-day seed lookback blocks 25977505-26027905. Blockscout's transfer index for this token confirms why: token_type ERC-721, total_supply=1, holders_count=1 -- this address is a single-NFT Fractional.art vault (InitializedProxy) holding the whole 'Twin Flames' set as one token id 0; its only Transfer event ever is the original 2021-11-23 mint/vault-deposit at block 13672738 (tx 0x7f383850dfb2c5f32832a60913d28cbabfa00134f9f48b925e4470c8e529b049), which is not a paid secondary sale (no Seaport/marketplace settlement, no buyer payment). No qualifying executed secondary sale of this NFT exists in this contract's entire history, let alone in the pinned window or the 7-day seed lookback. Per the request's own seed and missing definitions, the last-sale TWAP is therefore unavailable, not zero: I did not fabricate a uint256. The numeric field is set to the schema/guard floor (1 wei) purely to satisfy the mandatory uint256 type; it is not a computed price and should not be treated as one. Context only (not used in the TWAP): CoinGecko current floor_price for this collection was 22.22 ETH ($61,304) via api.coingecko.com/api/v3/nfts/{slug}, retrieved during this run; OpenSea's own floor could not be fetched live due to the missing API key."
