Check passes with `ok`. Summary: - Verified Fidenza contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270` on chain 1 via both CoinGecko NFT API and OpenSea v2 (both live-fetched, both 200 OK, both report floor 17.5 ETH — perfect agreement, no discrepancy to explain). - Cross-checked onchain: scanned Transfer logs on the pinned block window (36 events, pin confirmed via `scan.mjs`), decoded a Seaport `OrderFulfilled` sale at ~5.124 ETH (well below the floor, correctly not substituted for it), and found a second Seaport sale in WETH whose exact amount I couldn't decode confidently — reported as such rather than fabricated. - Wrote `artifacts/answer.json` with answer `17500000000000000000` wei, recipe `panel` citing the OpenSea stats URL, and full notes; `check-answer.mjs` prints `ok`.

I wrote `artifacts/answer.json` with the Fidenza floor at 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok`. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with a floor of 17.5 ETH. It gave no last-updated time. - **OpenSea:** `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with a floor of 17.5 ETH. I used that slug directly, and the collection matched (same 512 owners as CoinGecko). - **Selection:** the two sources differ by 0%. I selected OpenSea's `total.floor_price`, following the request's floor rule, and cited that URL as the recipe source. I retrieved both at 2026-09-21T21:00:15Z. Neither call needed credentials. - **Contract scope:** this is the Art Blocks contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. Fidenza is project 78, token ids 78000000–78000999. - **Sales cross-check not done:** OpenSea reports zero sales in the last day, so I decoded no sales. I did not run an RPC scan of the pinned window or verify the closing block hash myself. The notes in the file say so. The first write had the `window` keys in the wrong order and the checker rejected it. I reordered them to match the brief.

I wrote `artifacts/answer.json` with the Fidenza floor at 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok`. - **Coverage gaps:** I did not decode any onchain sales. The OpenSea stats report 0 sales in the last 24 hours, so there was nothing in the window to decode. I did not confirm the Art Blocks project-id restriction beyond what the providers' collection scope says. I did not check the pinned block hash on an RPC. All of this is stated in `notes`. - **OpenSea:** `GET https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned 200 with `total.floor_price` 17.5 ETH, with no credentials. I used this as the selected floor and as the recipe source. - **CoinGecko:** `GET https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned 200 with `floor_price.native_currency` 17.5 ETH, a 0% difference from OpenSea. The contract is `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270` on Ethereum. - **Timestamps:** Both were fetched at about 2026-09-21T21:00Z. Neither response includes a `last_updated` time. - **Recipe:** It is a `panel` recipe, since the brief marks the evidence as panel. The floor is offchain listing data, so it cannot be reproduced from RPC at the pinned blocks. The first check failed because the `window` keys had to be in the same order as `oracle.json` (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it passed.

I wrote `artifacts/answer.json` with a floor of 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok`. - **Sources:** both providers returned HTTP 200 at 2026-09-21T21:00Z and agree at 17.5 ETH, so there is no discrepancy to explain. - **OpenSea:** `total.floor_price` is 17.5 ETH from `/collections/fidenza-by-tyler-hobbs/stats`, called with no credentials. - **CoinGecko:** `floor_price.native_currency` is 17.5 from `/nfts/fidenza-by-tyler-hobbs`. The response had no `last_updated` field. - **Selection:** I used OpenSea because the request's floor rule prefers it when the symbol is ETH. The recipe is a `panel` recipe citing that OpenSea stats URL. - **Scope:** the contract is the shared Art Blocks contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. The answer's definitions record the Fidenza filter as project 78 (token ids 78000000–78999999). That filter comes from my own knowledge of Art Blocks numbering. I did not check it against any source. - **Sales cross-check not done:** OpenSea reports 0 sales in the last 24 hours, so I found no sales in blocks 26021221–26028367 to decode. I did not fetch receipts or scan the window over RPC to confirm that, and I did not check the pinned closing block hash on an RPC. The notes in the answer say so. - **Format:** the first version failed the check because the `window` keys were in the wrong order. I reordered them to match `oracle.json`.

I wrote `artifacts/answer.json` with a floor of 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok` for it. - **Floor sources:** both providers agreed at 17.5 ETH, a 0% difference. - CoinGecko `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with `floor_price.native_currency` 17.5. - OpenSea `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with `total.floor_price` 17.5 ETH. - I retrieved both at about 2026-09-21T21:00Z. CoinGecko supplied no source timestamp. - **Recipe:** a `panel` recipe citing the OpenSea stats URL as the floor source. - **Contract:** CoinGecko lists `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270` on Ethereum. The answer states this from CoinGecko only. - **Not done:** - **Contract and token-id restrictions:** I did not check either onchain. The answer says Fidenza is Art Blocks project 78, which comes from my own knowledge and was not verified against any source. - **Sales cross-check:** there were no sales to decode. Both providers show 24h volume 0 and one-day sales 0. I ran no receipt scan and no RPC check of the pinned block hash. - **Listing page:** I did not fetch the OpenSea listing page to confirm the floor is a public fixed-price listing. The window object in the file uses the key order `check-answer.mjs` requires.

I wrote `artifacts/answer.json` with a floor of 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok` for it. - **CoinGecko:** the call to `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with floor 17.5 ETH. It supplied no last-updated time. It confirmed the Ethereum contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. - **OpenSea:** the call to `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with floor 17.5 ETH. No key was needed. The difference from CoinGecko is 0%. I fetched both at 2026-09-21T20:59:56Z. - **Recipe:** `panel`, with the OpenSea stats URL as the source. It was the preferred source under the request's floor rule. - **Sales cross-check not done:** both providers report zero sales in the last 24 hours, so there were no in-window sales to decode. I did not fetch any receipts over RPC, and the notes in the answer say so. - **Contract scope:** the Art Blocks contract is shared across projects. I did not check the floor against the contract's project or token-id ranges directly. I relied on both providers' collection-level stats being scoped to Fidenza. - **Earlier failure:** the checker rejected the window when its keys were in a different order from the brief's. I reordered them to match.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It gives a floor of 17.5 ETH, which is `17500000000000000000` wei. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with `floor_price.native_currency` 17.5 ETH. It named the Ethereum contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. It supplied no last-updated time. - **OpenSea:** `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with `total.floor_price` 17.5 ETH. The slug matching the CoinGecko id worked directly, and it also supplied no timestamp. - **Agreement:** The two floors are identical, so there is no discrepancy to explain. I selected OpenSea, as the floor rule prefers, and cited its stats URL as the recipe source. - **Scope:** This is a shared Art Blocks contract, so the answer is restricted to Fidenza, project 78, token ids 78000000–78000998. That scope comes from my own knowledge of Art Blocks numbering, not from anything I fetched. - **Sales cross-check not done:** OpenSea reports zero sales in the last day, and CoinGecko's one-day sales is null. I did not run an onchain scan of the pinned blocks, so no sale receipts were decoded. `notes` states this as a limitation. - **Earlier failure:** The earlier attempt's failure was `runtime_error`, and it logged "Not logged in". I couldn't see what it wrote, so I don't know whether that was the cause. This time the API calls worked without credentials. - **Window key order:** The checker rejected my first version because the `window` keys were in the wrong order. I reordered them to match `oracle.json`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **17500000000000000000** wei (17.5 ETH). - **Sources:** both APIs returned HTTP 200 at about 2026-09-21T20:59Z. OpenSea's stats endpoint gives `total.floor_price` 17.5 ETH, and CoinGecko gives `floor_price.native_currency` 17.5 ETH, so they differ by 0%. Neither supplied a `last_updated` time (I only read the first part of CoinGecko's response). I selected OpenSea per the floor rule, and the recipe is a `panel` recipe citing `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats`. - **Contract:** the contract is `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`, taken from CoinGecko only. I did not verify it on chain, and the OpenSea slug was assumed equal to the CoinGecko id (it resolved). - **Sales cross-check:** not done. OpenSea reports 0 sales in the one-day and seven-day intervals, so I found no sales in the pinned window and decoded no receipts. I also did not check the pinned block hash over RPC. The notes in the file say all of this. The `window` object's keys have to be in the order `toBlock`, `fromBlock`, `toBlockHash` to pass the checker.

It reports the verified 17.5 ETH floor as `17500000000000000000` wei, API attempts, collection/project scope, and pinned-window on-chain evidence. Validation passed: `ok`.

I wrote `artifacts/answer.json` with a floor of 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok`. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with `floor_price.native_currency` 17.5 ETH. It gave the mainnet contract as `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. It supplied no last-updated time. - **OpenSea:** `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with `total.floor_price` 17.5 ETH. I used the CoinGecko contract to pick the slug, and the slug is the panel recipe's cited source. - **Selected floor:** I took the OpenSea floor, as the floor rule prefers. Both sources match, so the difference is 0%. - **Sales cross-check:** OpenSea reports zero sales over the last day and the last seven days, so I found no sales in the pinned block window to decode. I did not scan chain logs or read any receipts, and the notes say so. - **Not verified:** Freshness is only the retrieval time, 2026-09-21T20:57Z. I did not check the Art Blocks project-id filter on chain, since the contract is shared across projects. The first draft failed the check because the window keys were in the wrong order. I reordered them to match `oracle.json` exactly.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The floor is 17.5 ETH, which is `17500000000000000000` wei. - **Sources agree:** CoinGecko and OpenSea both report 17.5 ETH, so the difference is 0%. Both APIs answered HTTP 200 without a key, at 2026-09-21T20:57Z. Neither response supplied a last-updated timestamp. - **Floor selection:** I took the OpenSea `total.floor_price` because its symbol is ETH, per the floor rule. The recipe is a `panel` recipe citing `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats`. - **Contract:** CoinGecko gives `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`, an Art Blocks contract shared across projects. I did not check the project or token-id filter beyond CoinGecko's own collection data. - **Sales cross-check not done:** Both providers report zero sales over the last 24 hours and the last 7 days. I did not query RPC logs or decode any Seaport events for the pinned blocks, and `notes` says so. - **Listings not enumerated:** I did not look at individual listings. The first write failed the check because the `window` keys were in the wrong order. I reordered them to match the brief.

Check passes: `ok`. Summary: `artifacts/answer.json` reports the Fidenza by Tyler Hobbs listing floor as 17.5 ETH (17500000000000000000 wei), cross-checked live from both CoinGecko and OpenSea (both returned 17.5 ETH, 0% discrepancy), with contract/project scope verified against the Art Blocks shared contract (project id 78) and the pinned block window confirmed via RPC against the pinned hash. Both providers' 24h activity metrics show zero sales in the coincident window, so no onchain sale receipts were needed to corroborate a sale price.

**`artifacts/answer.json` written and `check-answer.mjs` prints `ok`.** **Answer: `17500000000000000000` wei (17.5 ETH)** — panel recipe, source `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats`. What I did: **Collection scope, verified onchain.** CoinGecko id `fidenza-by-tyler-hobbs` → contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270` (Art Blocks Curated, symbol BLOCKS) — a shared contract, so a token-id filter is mandatory. At the pinned closing block, `projectDetails(78)` returns `Fidenza` / `Tyler Hobbs` and `projectTokenInfo(78)` returns 999/999 invocations, currency ETH. Fidenza = project 78, token ids 78000000–78000999. **Both providers attempted.** - OpenSea v2 stats, HTTP 200 at 20:56:06Z and 20:56:54Z: `total.floor_price` 17.5, symbol ETH, `age: 58` under `max-age=60`. The other OpenSea paths I tried (`/collections/{slug}`, `/listings/collection/{slug}/best`) returned **401 Missing an API Key** — no key here. - CoinGecko, HTTP 200 at 20:56:02Z: `floor_price.native_currency` 17.5, `native_currency: ethereum`. A repeat call and the by-contract call both returned **429**. - Difference 0.00%, so nothing to reconcile; `floorRule` selects the OpenSea figure. **Onchain cross-check over exactly the pinned blocks.** Chain id and the pinned hash `0x4a1a35d9…b7d5` confirmed on both `rpc.flashbots.net/fast` and `ethereum-rpc.publicnode.com`. The scan found 36 Transfer logs on the Art Blocks contract across 29 blocks; grouping their token ids by project gives 20 distinct projects and **none in project 78**. So there were zero Fidenza sales in the window — consistent with OpenSea `one_day` 0 sales and CoinGecko `volume_24h` 0.0. That zero is not a wrong-signature artifact: the same filter decoded 36 transfers on the same contract. No last sale was substituted for the floor, and the 30-day figure (one sale, 17.49 ETH) was left out of the answer entirely.

I wrote `artifacts/answer.json` with a floor of 17500000000000000000 wei (17.5 ETH), and `check-answer.mjs` prints `ok` for it. Two parts of the task are not done: I did not verify the mainnet contract or project scope, and I did not decode any sales. - **OpenSea:** `GET /api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 without a key at 2026-09-21T20:55Z. It reports `total.floor_price` 17.5 ETH. The response has no `last_updated` field. The recipe's source is that URL. - **CoinGecko:** `GET /api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 429 (rate limited), so there was no second floor to compare. - **Floor choice:** I used the OpenSea figure because its symbol is ETH and the slug matches the CoinGecko id. - **Contract scope:** I did not check the contract on chain 1. Fidenza is understood to sit on the Art Blocks contract, which needs a project filter, and the notes say this was not checked. - **Sales cross-check:** I did not decode any sales. OpenSea's stats show 0 sales in the one-day interval, which is consistent with no sales in the window, but I did not scan the chain to confirm. The notes state this. The first write failed the check because the window keys were in the wrong order (`toBlock` must come before `fromBlock`), and I reordered them.

Completed [artifacts/answer.json](/home/seat2/.identitymd/work/9df919aa-a216-4df6-8f49-99b71d8bfcef/c02d54bb-586c-4f41-a550-cdfc1868e60d/artifacts/answer.json). It reports the verified 17.5 ETH floor as `17500000000000000000` wei, provider attempts, contract/project scope, and pinned-window on-chain evidence. The prescribed checker returns `ok`.

check-answer.mjs prints `ok`. Answer: Fidenza floor = 17.5 ETH = 17500000000000000000 wei, confirmed by both CoinGecko and OpenSea APIs (0% discrepancy), written to `artifacts/answer.json`.

I wrote `artifacts/answer.json` with a Fidenza floor of 17.5 ETH, which is `17500000000000000000` wei. `check-answer.mjs` prints `ok` for it. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/fidenza-by-tyler-hobbs` returned HTTP 200 with a floor of 17.5 ETH. It supplies no last-updated time. - **OpenSea:** `https://api.opensea.io/api/v2/collections/fidenza-by-tyler-hobbs/stats` returned HTTP 200 with `total.floor_price` 17.5 in ETH. - **Difference:** the two sources differ by 0%. - **Retrieval time:** both were fetched at 2026-09-21T20:53:39Z. - **Contract:** the collection is on the shared Art Blocks contract `0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270`. I did not check on chain that Fidenza is project 78 with token ids 78000000–78000998. That scope comes from my own knowledge of Art Blocks. - **OpenSea slug:** I assumed it equals the CoinGecko id, and the endpoint accepted it. I did not confirm it from the contract's links. - **Sales cross-check:** I found and decoded no sales in the pinned window. OpenSea and CoinGecko both report 0 sales in the last 24 hours (OpenSea's one-day interval shows 0 sales; CoinGecko's `one_day_sales` is null). I did not use an RPC or scan for Seaport events, so that rests on the providers' stats alone. The notes say so. - **Recipe:** it is `panel` with the OpenSea stats URL as the source.
