  "notes": "COLLECTION: CoinGecko id cryptoadz -> contract_address 0x1cb1a5e65610aeff2551a50f76a87a7d3fb649c6, asset_platform ethereum. Verified via https://api.opensea.io/api/v2/chain/ethereum/contract/0x1cb1a5e65610aeff2551a50f76a87a7d3fb649c6 (HTTP 200, 2026-09-21T21:20:40Z): chain ethereum, erc721, collection cryptoadz-by-gremplin, name 'CrypToadz by GREMPLIN'. Dedicated contract, so no token-id filter needed. API ATTEMPTS (UTC): (1) CoinGecko https://api.coingecko.com/api/v3/nfts/cryptoadz 21:20:11Z HTTP 200: floor_price.native_currency=0.273714 (native ethereum), usd 760.51; refetch 21:25:00Z unchanged; no last_updated field. (2) OpenSea https://api.opensea.io/api/v2/collections/cryptoadz-by-gremplin/stats 21:20:12Z HTTP 200: total.floor_price=0.27371398990000023, floor_price_symbol=ETH; refetch 21:25:00Z unchanged; no last_updated field. (3) OpenSea order-level endpoints /api/v2/listings/collection/cryptoadz-by-gremplin/best and /all returned HTTP 401 'Missing an API Key' (no credentials available), so the exact order-level wei amount was not retrievable; the stats endpoint succeeded, so no page fallback was required. SELECTION: floorRule prefers OpenSea stats total.floor_price (symbol ETH, verified scope) = 0.2737139899 ETH -> 273713989900000000 wei by exact decimal arithmetic (the double's trailing ~230 wei is float serialization noise below listing granularity). CoinGecko 0.273714 differs by 1.01e-8 ETH = 0.0000037%, i.e. the same listing rounded to 6 decimals; <1%, no investigation required. No averaging; no sale substituted for the floor. ONCHAIN (pinned blocks 26021226-26028372 = 2026-09-20T20:49:59Z..2026-09-21T20:49:59Z; eth_getLogs + receipts via https://rpc.flashbots.net/fast with halved ranges; toBlockHash 0xf0deb6a5...b967 matched the pin on rpc.flashbots.net/fast and rpc.mevblocker.io/fast): 21 ERC-721 Transfer logs in 7 txs, whole-window coverage. Exactly one decoded marketplace sale: tx 0xa98d24f4a58c38e04c01b582bba1095fda0902f82a1bff4b7ea713eb4afe5973, block 26025107, Seaport 1.6 (0x0000000000000068f116a894984e2db1123eb395) OrderFulfilled: token id 1146, seller 0x8258df8c7f2e0bf29e656d821fb903394ad6b79e -> buyer 0x83b97b9454d90791480cfda42c01d461d4d4eaa3, total ETH consideration incl. fees 699000000000000000 wei (0.699 ETH). Excluded non-sales: token 1785 round-trip between the same two wallets (blocks 26025020/26025026, loan-like events, no sale event); token 665 plain transfers (blocks 26023207/26023356); 15-toad single-tx bulk transfer (block 26021660, no attributable unit price); token 4608 wrap-like tx (block 26021465, ERC-1155 TransferSingle alongside, no sale event). DISCREPANCIES: OpenSea one_day interval (rolling 24h to ~21:20Z) reports 2 sales / 1.609 ETH vs 1 decoded sale in the pinned window ending 20:49:59Z; the averages (0.8045) imply a second 0.91 ETH sale in the ~30 min between window close and retrieval - a timing-scope difference, not a conflict. The floor 0.2737139899 ETH is well below the window's last sale 0.699 ETH, as expected: the floor is a live listing, never inferred from sales."
