  "notes": "Verified toBlockHash 0xbd39338f...9082ee for block 26035049 via public RPC https://ethereum-rpc.publicnode.com (eth_getBlockByNumber) — exact match. Scanned Transfer(address,address,uint256) logs at contract 0xf17bb82b6e9cc0075ae308e406e5198ba7320545 over blocks 25977505..26035049 (7-day seed lookback ~50400 blocks + the pinned 24h window) via https://rpc.mevblocker.io in 2000-block chunks, whole range, zero gaps/errors: 0 logs total. Contract confirmed correct (name()='Bond Bears', totalSupply()=126, code present at 'latest'). Since there is no ERC721 Transfer at all in this span, there is no OrderFulfilled/Seaport settlement or any other marketplace sale to verify either (Transfer is a necessary condition for any transfer-based sale). No OpenSea API key was available (api.opensea.io returned 401 Missing an API Key), so OpenSea collection events could not be queried directly; independent corroboration came from CoinGecko's the-bond-bears NFT endpoint, which reports volume_24h=0, one_day_sales=0, one_day_average_sale_price=null, and floor_price.native_currency=106.7 ETH (context only, not used as sales price). Per the request's own 'seed' and 'missing' definitions: no seed within 7 days before start and no in-window fill means the full-window last-sale TWAP is formally unavailable, and zero must not be used as a sentinel for missing data. Because answerType=uint256 requires a numeric value and guards.min=1, I report answer=1 wei as an explicit unavailability sentinel (clearly distinguishable from any real sale price) rather than fabricating a plausible-looking number; figure=0 records the qualifying in-window fill count (0). Limitation: full price history could not be cross-checked against OpenSea's own event feed due to missing API credentials; the on-chain Transfer-log scan is exhaustive and authoritative for whether any transfer-based sale occurred, however, so this limitation does not change the zero-sales conclusion."
