Compute the 24-hour time-weighted average OpenSea listing floor for Baby Bears on Ethereum mainnet, returning integer wei. CoinGecko collection id the-baby-bears. Verify exact contract/project scope and OpenSea slug. Use historical OpenSea orders/listings and corroborate order status, cancellations and fulfillments with on-chain calls/events over the pinned window. A floor is the lowest valid public ask, not the last sale or mean sale. Follow pinned definitions. If historical order coverage is insufficient, report inability and do not submit a fabricated numeric answer.

twap
TWAPwei=floor(sum(F_i_wei * duration_i_seconds)/86400), integrating each piecewise-constant minimum-ask interval. Account for listing starts/expiries, cancellation, fulfillment and invalidation. Use exact integer/rational arithmetic. Do not use VWAP, average sale, mean of irregular samples, current floor or 24h low as TWAP.
scope
Baby Bears; https://www.coingecko.com/en/nft/the-baby-bears. Verify chain 1 contract and OpenSea slug. Shared Art Blocks contracts require project/token-id restrictions. Do not combine migrated chains or wrapped and native collections.
metric
F(t) is the minimum total buyer-payable price among valid public single-NFT fixed-price ETH/WETH OpenSea listings in scope at time t, including mandatory fees. ETH/WETH are 1:1. Exclude bids, private listings, bundles and other currencies. Never infer F(t) from completed sales or transfers.
output
Use recipe.kind=panel and recipe.source as the actual OpenSea evidence URL. Notes (max 4000 chars): contract/project scope, slug, T0/T1, data URLs/times, pagination/coverage, intervals and weighted sum, result, representative tx hashes and decoded events, archive checks and limitations. Panel consensus is not an independently replayed chain proof.
source
Use official OpenSea APIs/collection data and verifiable order records; resolve the slug independently. Only use existing credentials and never disclose keys. Record 401/403/429 and archive-RPC limitations. CryptoPunks native market events may corroborate but cannot replace an unavailable OpenSea listing series.
window
Read T1 from the pinned toBlock timestamp; T0=T1-86400 seconds. Integrate [T0,T1). Report UTC endpoints, pinned block/hash and opening state provenance. Opening listings may predate fromBlock: obtain their state immediately before T0 without counting earlier sales in the window.
missing
If any interval lacks a verifiable floor, opening state or complete relevant order history, report insufficient coverage and DO NOT emit artifacts/answer.json with a substitute number. Zero is not a missing-data sentinel. Do not carry prices across unknown gaps. No sale does not mean no floor. Do not fall back to sale-price TWAP.
ranking
Fixed Ethereum market-cap rank 9, global rank 11, from https://www.coingecko.com/en/nft checked 2026-09-22T05:13:15.236Z. CoinGecko is used for collection selection, not as a substitute TWAP source.
evidence
Fetch complete historical OpenSea order/listing data plus opening valid asks. Validate signatures/order status, ownership/approvals, cancellations and Seaport fulfillments using chain-1 RPC/archive calls and receipts when available. Seaport events alone miss offchain signed asks; Seaport usage alone does not prove OpenSea origin. Transfers alone are not sales.
