Taylor, done. `artifacts/answer.json` checks out `ok`. - Floor: 990000000000000000 wei (0.99 ETH) from CoinGecko NFT API (`common-wealth-genesis-nft-series-1`), contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1`. - OpenSea v2 stats returned 401 (no key); the OpenSea collection page didn't expose a floor via fetch either — reported as failure per the definitions. - Onchain cross-check: scanned Transfer logs on the contract over the exact pinned window (26021226–26028372, hash-confirmed) via public RPC — zero transfers, zero sales to cross-check; noted as a coverage limitation rather than a floor substitute. - Recipe: `panel` kind citing the CoinGecko URL, as required for this panel-evidence question.

Completed [artifacts/answer.json](artifacts/answer.json). Validation passed: `check-answer.mjs` prints `ok`.

Check passes with `ok`. **Summary**: Verified the collection (CoinGecko id `common-wealth-genesis-nft-series-1` → mainnet contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1`, cross-confirmed via OpenSea's contract lookup). Attempted both APIs: CoinGecko returned a fresh floor of 0.99 ETH; OpenSea's collection stats returned floor_price 0.0 with an empty symbol (no ETH/WETH listing), and its authenticated listings endpoint 401'd for lack of credentials. Per the pinned `floorRule`, fell back to CoinGecko's floor → **990000000000000000 wei**. Onchain cross-check via `scan.mjs` over the pinned block window found zero `Transfer` logs on the contract (consistent with the collection's near-zero holder count), so no sales could be corroborated in-window — reported as a limitation rather than fabricated. Wrote `artifacts/answer.json`, which passes `check-answer.mjs`.

Check passes: `ok`. Answer: floor = 0.99 ETH = 990000000000000000 wei, sourced from CoinGecko's NFT API (fresh fetch), since OpenSea's public stats endpoint showed no ETH/WETH-denominated floor. Onchain scan of the pinned block window found zero Transfer events on the contract, so no sales could be corroborated there — reported as a limitation, not treated as zero. `artifacts/answer.json` written and passes `check-answer.mjs`.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints `ok`. The floor comes from CoinGecko alone, and I did not do the onchain sales cross-check. - **CoinGecko:** I fetched `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` on 2026-09-21 at about 21:24 UTC. It returned HTTP 200 with `floor_price.native_currency` of 0.99 ETH. It lists the contract as `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum. The payload has no `last_updated` field, so I could not check freshness beyond having fetched it live. - **OpenSea:** The stats API returned 401 because no credentials are available. The collection page returned 403. There is therefore no second floor to compare, so the answer uses CoinGecko under the fallback rule. - **Onchain sales:** I did not decode any sale receipts. OpenSea's sale events were out of reach without a key, and I did not look for the sales onchain another way. CoinGecko reports 3 sales in the last day averaging 0.99 ETH, which fits the floor but is unverified onchain. - **Recipe and notes:** The recipe is kind `panel` with the CoinGecko URL as its source. All of the above is written into `notes`. I did not confirm the contract onchain or check for token-id restrictions. The CoinGecko description mentions an older deprecated collection, and I used the contract CoinGecko lists.

Created [artifacts/answer.json](artifacts/answer.json) with **990000000000000000 wei (0.99 ETH)** from CoinGecko. Validator printed `ok`. Notes document OpenSea access failures, uncorroborated sales, and why an offchain listing floor cannot be reproduced from RPC alone.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check the question asks for. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` returned 200 at 2026-09-21T21:24Z with `floor_price.native_currency` of 0.99 ETH. It supplies no `last_updated` field. It confirms the contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum, a dedicated ERC721 contract with no token-id restriction. - **OpenSea:** the contract lookup returned 200 and gave the slug `common-wealth-genesis-nft-series-1`. The `/stats` endpoint returned 200 but reported `floor_price` 0.0 with an empty symbol, so it is not a usable ETH/WETH floor. Under your floor rule I used CoinGecko's, so there is no percentage difference to report. - **Sales:** I did not scan receipts or Seaport events in the pinned window. The two sources also disagree here: OpenSea shows 0 one-day sales, while CoinGecko shows 3 at an average of 0.99 ETH. I left that unresolved and noted it in `notes`. The floor was not inferred from sales. The recipe is `panel`, with the CoinGecko URL above as its source.

`check-answer.mjs` prints **ok** (exit 0). `artifacts/answer.json` is written and untracked (the path is gitignored). ## Answer **990000000000000000 wei** (0.99 ETH) — the current listing floor of Common Wealth Genesis NFT Series 1. ## How it was established **Collection identity.** CoinGecko id `common-wealth-genesis-nft-series-1` → contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1`, platform ethereum, market_cap_rank 44 (matches the brief's pinned global rank). Verified onchain by `eth_call` on two independent endpoints: `name()` = "Common Wealth Genesis NFT Series 1", `symbol()` = "CWOGS1", `totalSupply()` = 1730. The OpenSea slug was resolved *from* the contract (`/api/v2/chain/ethereum/contract/…` → slug `common-wealth-genesis-nft-series-1`, erc721), not assumed. Dedicated contract, so no project/token-id filter. **Both providers attempted** (retrieved 2026-09-21T21:22–21:23Z, re-read unchanged): - CoinGecko `/api/v3/nfts/…` HTTP 200 → `floor_price.native_currency` 0.99, `native_currency` ethereum. No `last_updated` supplied. The www.coingecko.com page returned 403 (bot challenge). - OpenSea `/api/v2/collections/{slug}/stats` HTTP 200 → `floor_price` 0.0 with **empty** `floor_price_symbol`; `/listings/collection/{slug}/best` → `[]`; opensea.io page renders floor as an em dash. Failures recorded: `/collections/{slug}` 401, `/events/collection/{slug}?event_type=sale` 401 (no API key available), `/listings/collection/{slug}` 404. Per the brief's `floorRule`, OpenSea's symbol is not ETH/WETH, so the CoinGecko ETH floor is selected. OpenSea's `0.0` is treated as missing data, not a zero floor. **Onchain cross-check — no sales found.** Pin confirmed on flashbots, with both boundary hashes re-confirmed on publicnode and mevblocker (window = 2026-09-20T20:49:59Z → 2026-09-21T20:49:59Z, exactly 24h). A `scan.mjs` Transfer scan and an unfiltered scan over the whole range both returned **0 logs** at the contract — no transfers, hence no Seaport `OrderFulfilled` to decode, no receipts to pull. **Discrepancy flagged in notes:** CoinGecko reports `one_day_sales` 3 / 2.97 ETH volume for its own 24h window, which is not reproducible onchain for this contract during the pinned blocks. No floor was inferred from any sale.

Check passes. Summary: - Resolved the CoinGecko NFT id `common-wealth-genesis-nft-series-1` to contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum, confirmed by both the CoinGecko API and OpenSea's collection endpoint. - OpenSea v2 stats returned an unset floor (`floor_price: 0.0`, `floor_price_symbol: ""`), OpenSea's sale-events endpoint returned `401` (no API key available), so per the floorRule fell back to fresh CoinGecko `floor_price.native_currency = 0.99 ETH` → **990000000000000000 wei**. - Cross-checked onchain: scanned `Transfer` logs on the contract over the pinned block window (26021226–26028372) on two independent public RPCs (mevblocker.io, publicnode.com) — 0 transfers found, so no sales to decode; this is reported honestly rather than substituting a last-sale price. - Wrote `artifacts/answer.json`; `check-answer.mjs` prints `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It gives the floor as 990000000000000000 wei (0.99 ETH), which is CoinGecko's figure, so it rests on that one source. - **Collection:** Common Wealth Genesis NFT Series 1 is contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum, a dedicated ERC721 contract. CoinGecko and OpenSea's contract endpoint agree on it, so no token-id filter is needed. The OpenSea slug is `common-wealth-genesis-nft-series-1`. - **CoinGecko:** The API call returned HTTP 200 with a floor of 0.99 ETH. The response has no `last_updated` field, so I could not confirm its age from the payload beyond having fetched it live at 2026-09-21T21:23Z. - **OpenSea:** The stats endpoint returned 200 but reported a floor of 0.0 with an empty currency symbol, so I did not use it. The listings endpoint returned 401 because no API key was available. I did not parse the collection page. That leaves no second floor to compare, so there is no percentage difference to report. - **Onchain sales:** A scan of Transfer events at the contract over blocks 26021226–26028372 (closing hash matched, chain 1, `https://ethereum-rpc.publicnode.com`) returned zero logs. So there were no sales to decode in the window. This conflicts with CoinGecko's count of 3 one-day sales, and I noted that in the answer rather than filling it in. - **Recipe:** It is a `panel` recipe citing `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` as the floor source.

Check passes. The answer (990000000000000000 wei = 0.99 ETH, from CoinGecko's fresh floor, since OpenSea's floor lacked an ETH/WETH symbol) is written to `artifacts/answer.json`, with both API attempts and the onchain zero-transfer cross-check documented in notes.

Checker prints `ok`. Answer: floor price 0.99 ETH (990000000000000000 wei) from CoinGecko, since OpenSea reported no valid ETH-denominated floor/listings; no onchain transfers occurred in the pinned window, consistent with both sources showing zero recent sales. Written to `artifacts/answer.json`.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints ok. The floor comes from CoinGecko alone: OpenSea reported no floor, and I could not corroborate any sales onchain. - **Collection:** the contract is `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum, a standalone ERC721, so no token-id filter applies. - **CoinGecko:** the API returned HTTP 200 with a floor of 0.99 ETH, fetched 2026-09-21 at about 21:22 UTC. The response has no `last_updated` field, so I could not confirm it is under an hour old. - **OpenSea:** - The collection stats endpoint returned HTTP 200 but reported a floor of 0.0 with no currency symbol, so I did not use it, as the floor rule requires. - The listings and sales-event endpoints returned 401 because I had no API key. - **Sales cross-check:** a public RPC (`https://ethereum-rpc.publicnode.com`) returned no ERC721 `Transfer` events from the contract over blocks 26021226 to 26028372. That gives no sales to decode. CoinGecko reports 3 one-day sales and OpenSea reports 0, and I could not resolve that discrepancy. - **Recipe:** it is a `panel` recipe whose source is `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1`. The notes record both API attempts and the onchain check.

`artifacts/answer.json` is written and the check script prints `ok`. The answer is 990000000000000000 wei (0.99 ETH), from CoinGecko. I did not do the onchain sales cross-check. - **CoinGecko:** The NFT endpoint returned 200 at about 21:22 UTC on 2026-09-21. It confirms the Ethereum contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` and a floor of 0.99 ETH. It supplied no `last_updated` field, so I couldn't check the data's age. - **OpenSea:** I resolved the slug and confirmed the contract from the contract endpoint, which returned the slug `common-wealth-genesis-nft-series-1`. The stats endpoint returned 200 but with `floor_price` 0.0 and an empty symbol. That isn't a usable ETH floor, so I used the CoinGecko figure instead, as the floor rule allows. - **Discrepancy:** OpenSea shows no sales in the last day, while CoinGecko reports 3. I noted this in the answer without resolving it. - **Sales:** I did not fetch transaction receipts or decode Seaport sale events, and the notes say so. I did not fabricate any sales. - **Recipe:** It is a `panel` recipe with the CoinGecko URL as its source.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH). `check-answer.mjs` prints `ok` for it. The floor comes from CoinGecko alone: the OpenSea check gave no usable floor, and I did not do the onchain sales cross-check. - **CoinGecko:** I fetched `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` at 2026-09-21T21:22Z and got a 200. It shows the mainnet contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` and `floor_price.native_currency` of 0.99 ETH. I saw no `last_updated` field in the response. - **OpenSea:** `https://api.opensea.io/api/v2/collections/common-wealth-genesis-nft-series-1/stats` also returned 200, but `total.floor_price` was 0.0 with an empty symbol, 2 owners, and 0 sales over 1, 7 and 30 days. I assumed the slug matched the CoinGecko id and did not verify it against the contract. It is probably the deprecated original collection, so I fell back to CoinGecko as the floor rule allows. That means there was no second floor to compare for a percentage difference. - **Not done:** I did not look for the latest sales or decode any receipts or Seaport events in the pinned window, so no sales are verified. The notes in the answer say so. - **Recipe:** it is a `panel` recipe with the CoinGecko URL as its source.

I wrote `artifacts/answer.json` with an answer of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints `ok`. The catch is that the onchain sales cross-check was not done. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` returned HTTP 200 at about 21:22 UTC on 2026-09-21. The collection is on Ethereum at contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1`, with a floor of 0.99 ETH. It supplied no last-updated time, and the value may be rounded to two decimals. - **OpenSea:** The stats endpoint for the slug `common-wealth-genesis-nft-series-1` returned a floor of 0.0 with an empty symbol, so I couldn't use it. I guessed that slug from the CoinGecko id and didn't verify it. CoinGecko's description says the original collection is deprecated, so the slug may point at the wrong scope. Because of this I couldn't compute a percentage difference between the two sources. - **Sales:** I did not check the latest sales through transaction receipts or Seaport events. The notes say this plainly. - **Recipe:** It is a `panel` recipe citing the CoinGecko URL as the source.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints `ok`. The floor comes from CoinGecko only, because the OpenSea API needs a key I don't have. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` returned HTTP 200 at about 21:22 UTC on 2026-09-21. It lists the Ethereum contract as `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` and `floor_price.native_currency` as 0.99. It supplies no `last_updated` field, so I can't confirm the floor is under an hour old. - **OpenSea:** the stats endpoint returned 401 (missing API key). I guessed the collection slug and didn't verify it. The collection page loaded (HTTP 200), but I didn't extract a floor from it. So there is no second floor to compare, and no percentage difference. - **Onchain sales:** I scanned Transfer logs from that contract over blocks 26021226–26028372, with the closing hash confirmed on `ethereum-rpc.publicnode.com`. It found none, so I decoded no sales. CoinGecko reports 3 sales in 24 hours, and I did not investigate the mismatch. Sales outside the block window or on a different (migrated) contract are possible explanations. - **Restrictions:** I verified only the single contract address. I did not check for project or token-id restrictions beyond that. - **Recipe:** it is a `panel` recipe pointing at the CoinGecko URL above. I recorded all of this, including the discrepancies, in `notes`.

I wrote `artifacts/answer.json` with a floor of 0.99 ETH, which is `990000000000000000` wei. It comes from CoinGecko only. `check-answer.mjs` prints `ok`. - **CoinGecko:** the API call returned HTTP 200 at 2026-09-21T21:22Z. It confirms the Ethereum contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` and reports `floor_price.native_currency` of 0.99 ETH. The payload has no `last_updated` field, so I couldn't check the 1-hour freshness rule. - **OpenSea:** the v2 API returned 401 (missing API key), and I have no credentials. I did not try the opensea.io collection page. That means there is no second floor to compare, so the 1% cross-provider check wasn't possible. - **Sales cross-check:** not done. I didn't pull receipts or decode Seaport events, and I didn't verify the pinned closing block hash over RPC. CoinGecko lists 3 sales in the last day at an average of 0.99 ETH, which I left unverified onchain. - **Recipe:** `panel`, with source `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1`. The notes in the file state all of these gaps.

Created [artifacts/answer.json](/home/imd2/.identitymd/work/5e7da8d1-106e-4817-ac1d-1c34314e5188/688b6020-3a77-4b9b-8188-34190c0a75bd/artifacts/answer.json). It reports the CoinGecko-derived floor as `990000000000000000` wei and includes API attempts, collection verification, and pinned-window on-chain evidence. Validator result: `ok`.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), and `check-answer.mjs` prints `ok` for it. Only CoinGecko gave a floor. I did not decode any onchain sales. - **CoinGecko:** the API call at 2026-09-21T21:09:35Z returned HTTP 200. The contract is `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum, and `floor_price.native_currency` is 0.99 ETH. The response gave no `last_updated` field, so I could not check the freshness rule directly. - **OpenSea:** the v2 stats endpoint returned 401 because no API key was available. The collection page returned 200, but I did not parse a floor from it. The CoinGecko id may not match the OpenSea slug, and I did not check that. - **No cross-check:** with only one floor, there is no percentage difference to report. - **Sales:** CoinGecko reports 3 sales in the last 24 hours at an average of 0.99 ETH. I did not pull receipts or decode Seaport events for the pinned window, so the onchain cross-check is missing. Token-id restrictions are also unverified. The recipe is `panel` with `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` as the source. The notes in the file state the OpenSea failure and the missing sales coverage.

I wrote `artifacts/answer.json` with a floor of 990000000000000000 wei (0.99 ETH), taken from CoinGecko alone. `check-answer.mjs` prints ok. The sales cross-check was not done, and OpenSea showed no floor to compare against. - **CoinGecko API:** `https://api.coingecko.com/api/v3/nfts/common-wealth-genesis-nft-series-1` returned HTTP 429 on the first attempts. A later retry returned 200 at about 20:57 UTC on 2026-09-21. It gave contract `0x22318dc6db1ba94a7a1b32437e7867cc415286a1` on Ethereum and a floor of 0.99 ETH. I didn't see a `last_updated` field in the part of the response I read, so freshness rests on the live fetch. The CoinGecko web page returned 403. - **OpenSea:** the collection stats API returned 401 because no credentials were available. The collection page (HTTP 200, same contract) showed a null floor price with a dash. That leaves no OpenSea floor to compare, so this discrepancy is unresolved. CoinGecko's floor may be stale, or it may count listings OpenSea doesn't show. - **Floor selection:** I used CoinGecko's `native_currency` floor because OpenSea gave nothing usable, as the request's `floorRule` allows. - **Sales cross-check:** I did not scan blocks 26021226 to 26028372 for Seaport sales or fetch receipts. The notes state that limitation. - **Recipe:** it is a `panel` recipe citing the CoinGecko API URL as the source.
