I wrote `artifacts/answer.json` with a floor of 83399999000000000 wei (0.083399999 ETH). `check-answer.mjs` prints `ok` for it. I did not do the onchain sales cross-check the question asks for. I decoded no receipts or Seaport sale events for the pinned blocks, so the answer lists no sale transactions. The floor was not inferred from sales. The notes in the file say this too. - **Collection:** CoinGecko lists `veefriends-series-2` at contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum. OpenSea's slug `veefriends-series-2` matches: 19,937 owners there against 19,941 on CoinGecko. - **OpenSea:** the collection stats endpoint returned HTTP 200 with `total.floor_price` 0.083399999 ETH. I used this figure because the request prefers it when the symbol is ETH and the collection matches. - **CoinGecko:** the NFT endpoint returned HTTP 200 with a floor of 0.0834 ETH and no `last_updated` field. The two floors differ only by rounding. - **Retrieval time:** both were fetched at 2026-09-21T21:21Z. - **Recipe:** a `panel` recipe with the OpenSea stats URL as its source. - **Window:** copied from `oracle.json`. The checker rejected my first draft because the window keys were in the wrong order, and I fixed that.

I wrote `artifacts/answer.json` with a floor of 83399999000000000 wei (0.083399999 ETH), and the check script prints `ok` for it. I did not do the sales cross-check the question asks for. I didn't decode any sales or Seaport events from the receipts in blocks 26021223 to 26028369, so no sale tx hashes are reported. `notes` says so. - **OpenSea:** `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` returned HTTP 200 at 2026-09-21T21:10Z, with total floor 0.083399999 ETH. I used this figure, following the request's floor rule, because its symbol is ETH. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned HTTP 200 with a floor of 0.0834 ETH. It gives the collection as contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum, which I took as the scope (a dedicated contract, so no token-id filter). The two floors differ by about 0.0000012%, which is rounding. - **Source timestamps:** neither API supplied a last-updated time, so the only timestamp is my retrieval time. - **Slug:** OpenSea accepted the slug `veefriends-series-2`. I didn't separately verify it against the contract's links. - **Recipe:** a `panel` recipe citing the OpenSea stats URL. The floor is an offchain listing, so the deployer can't reproduce it from the pinned blocks.

Created [artifacts/answer.json](artifacts/answer.json) with **83,399,999,000,000,000 wei**, both API attempts, and three decoded sales. Checker returned `ok`. The notes explain that public RPC can corroborate sales but cannot reproduce an offchain listing floor.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 83399999000000000 wei** (0.083399999 ETH), recipe `{ kind: "panel", source: "https://api.opensea.io/api/v2/collections/veefriends-series-2/stats" }`. What I did: - **Collection scope verified.** CoinGecko id `veefriends-series-2` → contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18`, platform ethereum, market_cap_rank 22 (matches the brief's pinned rank). Confirmed onchain at the closing block: `name()` = "VeeFriends Series 2", `totalSupply()` = 55555. The OpenSea slug was resolved from the collection endpoint, not assumed: it lists exactly that one mainnet contract, so no token-id filter is needed. - **Both providers attempted.** OpenSea v2 stats returned 200 twice (21:01:11Z, 21:02:38Z) with `floor_price` 0.083399999, symbol ETH. OpenSea's keyed listings endpoint returned 401 (no key available). CoinGecko's NFT API returned 429 twice and the web page 403 (challenge), then succeeded at 21:02:32Z with `floor_price.native_currency` 0.0835 ETH. CoinGecko is 0.1199% above OpenSea — under the 1% threshold; `floorRule` selects the OpenSea value. - **Onchain corroboration over exactly the pinned blocks.** Pin confirmed on flashbots and re-confirmed on publicnode; 59 Transfer logs in 56 txs. The latest sales are three Seaport 1.6 `OrderFulfilled` events in tx `0x28bd5f…0a317` at block 26027989 (native-ETH consideration): tokens 50340 / 43588 / 43380 at 0.0835 / 0.085 / 0.090 ETH. Used as corroboration only — the floor is not derived from sales. One judgment call worth flagging: the provider's 0.083399999 is carried verbatim into wei (`83399999000000000`) rather than rounded to 0.0834, per the "exact decimal arithmetic" definition; a panel member who rounds would land on a different integer.

I wrote `artifacts/answer.json` with a floor of **83399999000000000 wei** (0.083399999 ETH), and `check-answer.mjs` prints `ok`. The onchain sales cross-check the task asked for was not done. - **Source:** OpenSea `GET https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` returned HTTP 200 without a key at 2026-09-21T21:01Z. `total.floor_price` was 0.083399999 with symbol ETH. The definitions say to prefer this figure when the symbol is ETH and the collection scope matches, so I used it. - **CoinGecko:** `GET https://api.coingecko.com/api/v3/nfts/veefriends-series-2` also returned HTTP 200. It gave `floor_price.native_currency` 0.0835 ETH and contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum. That is about 0.12% above OpenSea, under the 1% investigation threshold. - **Timestamps:** neither API supplied a `last_updated` or other timestamp, so freshness rests on my retrieval time. - **Recipe:** `panel`, with the OpenSea stats URL as the source. - **Not done:** - I did not decode any sales from receipts in the pinned blocks. - I did not check the closing block hash over RPC. - I did not confirm the OpenSea slug through the collection's contract links; I only matched it to CoinGecko's `web_slug`. I said all three in `notes`.

I wrote `artifacts/answer.json` with a floor of 83399999000000000 wei (0.083399999 ETH), and `check-answer.mjs` prints `ok`. The three-sale onchain cross-check is not done, so no sales are reported. - **Floor source:** OpenSea `GET https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` returned 200 with no API key. `total.floor_price` was 0.083399999 ETH, retrieved 2026-09-21T20:57Z. It supplied no `last_updated` time. The recipe is `panel`, with that URL as the source. - **Scope:** the OpenSea collection is named "VeeFriends Series 2" and is verified. Its description matches CoinGecko's. - **CoinGecko:** `GET https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned 200 with a floor of 0.0835 ETH. That is about 0.12% above OpenSea, under the 1% investigation threshold. The two floors are reported separately and not averaged. - **Contract:** CoinGecko lists 0x9378368ba6b85c1fba5b131b530f5f5bedf21a18 on Ethereum. I did not re-verify it on chain with an RPC call. - **Sales:** the OpenSea events endpoint returned 401 because it needs an API key, and none was available. I did not decode any sales from receipts. The notes state this. I also reordered the `window` keys to match the brief's order, which the checker requires.

The check passes. Summary: - Verified VeeFriends Series 2 contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` via CoinGecko's NFT id, confirmed the pinned block hash on-chain via public RPC. - Fetched both CoinGecko NFT API (floor 0.0835 ETH) and OpenSea v2 collection stats (floor 0.083399999 ETH) — both succeeded, discrepancy 0.12% (<1%, explained). - Per the request's `floorRule`, selected OpenSea's ETH-denominated `total.floor_price` → **83,399,999,000,000,000 wei**. - Cross-checked one decoded on-chain sale (0.088 ETH, Blur marketplace, token #47790, block 26027063) within the pinned window as corroboration, not a floor substitute. - Wrote `artifacts/answer.json` with the `panel` recipe citing the OpenSea stats URL; `check-answer.mjs` reports `ok`.

Completed [artifacts/answer.json](/home/imd1/.identitymd/work/2da4a319-c5eb-48d9-af15-484a608ce59d/0a3c982e-64a9-4b71-b483-1a7b27db7641/artifacts/answer.json). Validation passed: `check-answer.mjs` printed `ok`.

Taylor — done. `artifacts/answer.json` written and passes `check-answer.mjs`. Floor: 0.0835 ETH = **83,500,000,000,000,000 wei**, from CoinGecko's NFT API (OpenSea v2 stats returned 401; OpenSea's own collection page corroborated at 0.0834 ETH, 0.12% apart). Cross-checked against 4 decoded Seaport `OrderFulfilled` sales inside the pinned block window (block 26027989), 3 of which bracket the reported floor.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **83399999000000000** wei, which is OpenSea's `total.floor_price` of 0.083399999 ETH. - **Scope:** the contract is `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum. It is a single-contract collection with no token-id filter. CoinGecko and OpenSea's collection endpoint both list it, which confirms the `veefriends-series-2` slug. - **CoinGecko:** the API returned 200 with a floor of 0.0835 ETH. It supplies no `last_updated` field. - **OpenSea:** the stats endpoint returned 200 with a floor of 0.083399999 ETH. I chose it under the floor rule because the symbol is ETH and the scope matches. - **Difference:** the two floors differ by about 0.12%, under the 1% threshold. I put that down to rounding or update lag, but did not investigate further. - **Retrieval time:** I fetched both around 20:56 UTC on 2026-09-21, without credentials. - **Recipe:** it is `panel`, with the OpenSea stats URL as its source. **Sales cross-check not done:** OpenSea's sale-events endpoint returned "Missing an API Key", so I found no sales through the API and decoded no receipts or Seaport events. On chain, I confirmed the pinned closing hash on `ethereum-rpc.publicnode.com`, but only on that one endpoint. The scan found 59 ERC721 Transfer logs on the contract across the window. A Transfer alone doesn't prove a sale, so `notes` claims no sale prices. That limitation is stated there. The first `check-answer.mjs` run failed on key order inside `window`, and I reordered it to match the brief.

Check passes. `artifacts/answer.json` is written with the panel recipe: floor = 83,399,999,000,000,000 wei (0.083399999 ETH) from OpenSea's collection stats endpoint, cross-checked against CoinGecko (0.0835 ETH, 0.12% difference) and corroborated by a decoded Seaport `OrderFulfilled` sale in the pinned block window.

I wrote `artifacts/answer.json` with a floor of **83399999000000000 wei** (0.083399999 ETH). It passes `check-answer.mjs` (prints `ok`). The sales cross-check the question asked for was not done, so there are no transaction hashes in the answer. - **Floor source:** the OpenSea v2 stats endpoint, `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats`. It returned HTTP 200 with no key, and the floor is quoted in ETH. I fetched it around 20:55 UTC on 2026-09-21. It supplies no `last_updated` field, so I couldn't check its age beyond having fetched it fresh. - **Collection:** OpenSea's collection endpoint and CoinGecko both give contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum, so the two sources cover the same collection. It is a dedicated contract, so no token-id filter applies. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned HTTP 200 with a floor of 0.0835 ETH. That is 0.12% above OpenSea, under the 1% threshold that would need investigating. I used OpenSea, as the request's floor rule prefers, and did not average the two. - **Sales:** I didn't decode any sales over blocks 26021223–26028369. I also used no RPC, so I didn't confirm the pinned block hash myself. The notes in the file say both of these plainly. - **Recipe:** it is a `panel` recipe pointing at the OpenSea stats URL.

I wrote `artifacts/answer.json` with a floor of 83399999000000000 wei (0.083399999 ETH), and `check-answer.mjs` prints `ok` for it. The onchain sales cross-check the question asked for was not done. - **Floor source:** the OpenSea stats endpoint `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` returned HTTP 200 with `total.floor_price` 0.083399999 ETH. I retrieved it at 2026-09-21T20:54Z with no API keys, and it supplied no `last_updated` time. - **Collection:** the OpenSea collection endpoint and CoinGecko both give contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum, so there are no token-id restrictions to apply. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned HTTP 200 with a floor of 0.0835 ETH. That is about 0.12% above OpenSea, under the 1% threshold, and I did not average the two. - **Sales gap:** I did not pull receipts or decode the Seaport `OrderFulfilled` events for the latest sales in blocks 26021223–26028369. The notes say so. They also mention OpenSea's one-day figure of 7 sales for 0.5945 ETH, which I did not verify against the pinned blocks. - **Recipe:** it is a `panel` recipe whose source is the OpenSea stats URL above.

I wrote `artifacts/answer.json` with a floor of 83399999000000000 wei (0.083399999 ETH). It's from OpenSea's stats endpoint, and `check-answer.mjs` prints `ok`. I did not do the on-chain sales cross-check, and the notes in the file say so. - **Collection scope:** CoinGecko lists the mainnet contract as `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18`. It is a dedicated contract, so no token-id filter applies. - **OpenSea:** the collection endpoint returned 200 with slug `veefriends-series-2` (verified). The stats endpoint returned `total.floor_price` 0.083399999 in ETH. I chose this value because the symbol is ETH and the scope matches, as the floor rule prefers. - **CoinGecko:** the API returned 200 with `floor_price.native_currency` 0.0835. That is about 0.12% above OpenSea, under the 1% investigation threshold, so I recorded it and did not average. - **Timing:** both fetches ran at 2026-09-21T20:54 UTC. Neither response carried a `last_updated` timestamp, and the notes say that. - **Recipe:** `panel`, with source `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats`. - **On-chain sales:** I did not decode any Seaport `OrderFulfilled` receipts in blocks 26021223–26028369, because this run had no execution profile. The notes claim no sales.

I wrote `artifacts/answer.json` with a floor of **83399999000000000 wei** (0.083399999 ETH). `check-answer.mjs` prints `ok`. I skipped the sales cross-check the question asked for. - **OpenSea:** the stats endpoint `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` returned 200 without credentials. It reported `total.floor_price` 0.083399999 in ETH, and I used that per the floor rule. It gave no last-updated time. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned 200 with a floor of 0.0835 ETH. That is about 0.12% above OpenSea, under the 1% threshold. It also gave no last-updated time. - **Collection:** the contract is `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum. It is a dedicated contract, so no token-id filter applies. OpenSea's owner count (19937) is close to CoinGecko's (19941), so the slug matches the same collection. - **Sales cross-check not done:** I did not look up the latest sales in blocks 26021223–26028369 or decode their receipts. The notes say so, and no sale price stands in for the floor. - **Recipe:** it is a `panel` recipe whose source is the OpenSea stats URL above.

I wrote `artifacts/answer.json` with a floor of **83399999000000000 wei** (0.083399999 ETH). `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check the question asks for. - **OpenSea:** I fetched `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats` at 2026-09-21T20:54:51Z. It returned HTTP 200 with `total.floor_price` of 0.083399999 ETH. I used the slug directly rather than resolving it from the contract, and I did not verify the slug-to-contract link beyond the stats looking like a Series 2-sized collection (59,208 total sales). No timestamp came back. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/veefriends-series-2` returned HTTP 200. It gave contract `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum and a floor of 0.0835 ETH. It gave no last-updated time either. - **Discrepancy:** The two floors differ by about 0.12%, under the 1% investigation threshold, which I put down to refresh timing. I used OpenSea per the floor rule and did not average the two. - **Sales cross-check not done:** I did not fetch sale events or decode receipts over blocks 26021223–26028369, so no sale tx, token id or price is reported. The notes say this. - **Recipe:** `panel`, with the OpenSea stats URL as the source.

I wrote `artifacts/answer.json` with a floor of **83399999000000000 wei** (0.083399999 ETH), and `check-answer.mjs` prints `ok`. I did not do the on-chain sales cross-check. - **Source:** the OpenSea stats API returned `total.floor_price` 0.083399999 with symbol ETH. The URL is `https://api.opensea.io/api/v2/collections/veefriends-series-2/stats`, retrieved 2026-09-21T20:54:50Z. The slug `veefriends-series-2` returned a valid response, but I did not separately verify it against the contract. - **Cross-check:** the CoinGecko NFT API returned 0.0835 ETH, about 0.12% higher, which is under the 1% threshold. I used OpenSea because the floor rule prefers it when the symbol is ETH and the scope matches. - **Contract:** CoinGecko lists `0x9378368ba6b85c1fba5b131b530f5f5bedf21a18` on Ethereum. I did not check the contract on-chain or look for token-id restrictions. - **Sales:** I decoded no receipts or Seaport `OrderFulfilled` events, and used no RPC. The notes say so, so the answer carries no on-chain sale evidence. - **Recipe:** it is kind `panel`, citing the OpenSea URL above. I fixed one failure along the way: the checker rejected the `window` object because its keys were in the wrong order, and I reordered them to match `oracle.json`.
