Answer this question about chain 1 over blocks 26022887 to 26023187, exactly as .imd/reads/oracle.json pins it: What is the floor price of Mutant Ape Yacht Club (MutantApeYachtClub, contract 0x60e4d786628fea6478f785a6d7e704777c86a7c6) on Ethereum mainnet, in wei, as of the pinned window? Read the lowest active listing on a major marketplace and name the source. Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Created [artifacts/answer.json](artifacts/answer.json); checker prints `ok`. Recorded OpenSea’s observed listing: `869899000000000000` wei. The artifact explicitly marks it provisional: the historical minimum and RPC-only reproduction could not be established, so those acceptance criteria remain unmet.
Created `artifacts/answer.json`; checker prints `ok`. Recorded OpenSea’s observed price: **869899000000000000 wei**. The file explicitly documents that the exact historical floor and RPC-only reproducibility remain unverified.
`artifacts/answer.json` is written and passes the plane's checker (`ok`). **Answer: 848500000000000000 wei** (0.8485 ETH) — MAYC floor on OpenSea, token #13650, at the pinned closing block. What I did: - **Pinned the window on chain first.** `eth_getBlockByNumber(0x18d1513)` on `eth.drpc.org` and independently on `ethereum-rpc.publicnode.com` both return `0x407a3220…f906e058`, matching the brief's `toBlockHash`, timestamp 1789961075 = 2026-09-21T03:24:35Z. No `eth_getLogs` scan applies to a floor-price question, so `scan.mjs` yielded no figure; the window only fixes the instant. - **Read the floor.** The brief marks this `"evidence": "panel"`, so the recipe is `{ kind: "panel", source }`. OpenSea's own API returns 401 without a key and its site 403s a plain fetch, and I hold no key, so I read the OpenSea listing through two independent keyless mirrors that both name OpenSea as its origin: - `api-bff.nftpricefloor.com` → `currentFloorNative 0.8485`, `currentFloorOrigin "opensea"`, token 13650, snapshot 03:30:42Z - `api.coingecko.com/api/v3/nfts/mutant-ape-yacht-club` → `floor_price.native_currency 0.848499` (the same listing through its own conversion) - Blur (403, Cloudflare) and Magic Eden (400/403) were not readable from here; both mirrors place the collection floor on OpenSea. That limitation, the full chain of custody, and every endpoint used are stated in `notes`, and the open choices (ETH listings only, collection-wide, snapshot nearest the closing block, rounding) are under `definitions`. The file is left untracked at the repo root for the daemon to upload; nothing outside `artifacts/answer.json` was created or modified.
Created `artifacts/answer.json`; checker prints `ok`. Recorded **848500000000000000 wei**, from a Blur listing displayed on [OpenSea](https://opensea.io/collection/mutant-ape-yacht-club). The artifact explicitly marks the limitation: historical floor verification and RPC-only reproduction remain unsatisfied.
Done. `artifacts/answer.json` is written (untracked, excluded via `.git/info/exclude`, as the daemon expects) and `check-answer.mjs` prints `ok`. **Answer:** `848500000000000000` wei (0.8485 ETH), MAYC floor as of block 26023187. **How it was computed** - Pinned closing block confirmed on two operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): hash matches `0x407a32…e058`, timestamp 2026-09-21T03:24:35Z. Chain head was only 24 blocks past the closing block when I read, so a live read is effectively as-of the window. - Floor read from OpenSea's public v2 stats endpoint (no key needed): `total.floor_price = 0.8485 ETH`, unchanged across two reads ~4–6 minutes after the closing block. Converted to wei ×10¹⁸. - Recipe is `{ kind: "panel", source: "https://api.opensea.io/api/v2/collections/mutant-ape-yacht-club/stats" }`, since the brief is `evidence: "panel"` and the floor is an off-chain listing. **Caveats, stated in `notes`/`definitions`:** Blur returned a bot-challenge page and Magic Eden's public endpoints answered Not Found / no healthy upstream, so OpenSea is the single source cited. The ~6-minute gap between the closing block and the read is a small but nonzero risk that another member sees a different lowest ask. The previous attempt failed simply because `artifacts/` was never created; that's fixed here.

I wrote `artifacts/answer.json`. My answer is **848500000000000000 wei** (0.8485 ETH), the lowest active Mutant Ape Yacht Club listing on OpenSea. The answer checker (`check-answer.mjs`) prints `ok`. I left the file untracked, as instructed. **How I got it** - **Closing block:** I fetched block 26023187 from `https://ethereum-rpc.publicnode.com`. Its hash matches the pinned `0x407a3220…6e058`, and its timestamp is 2026-09-21T03:24:35Z. - **Source:** OpenSea's public collection stats (`https://api.opensea.io/api/v2/collections/mutant-ape-yacht-club/stats`) gave a floor of 0.8485 ETH. This is the `panel` recipe's source. - **Cross-check:** CoinGecko's NFT endpoint gave 0.848499 ETH, the same floor after rounding. - **Output fields:** The request id, chain and window are copied exactly from `oracle.json`. I added the source under `definitions`, and the notes explain the method. **Limits** - **Read time:** I read the floor live at about 03:29Z, roughly 4.5 minutes after the closing block. It is not an archived snapshot at that block's exact time, so the floor could have moved in those minutes. Both sources agreed. - **Other marketplaces:** I couldn't read Blur (bot-protection page) or Magic Eden (its public API returned "Not Found" or "no healthy upstream"), so I didn't compare them. - **Single listing:** OpenSea's endpoint for individual listings needs an API key, so I relied on its summary floor figure instead of reading the order itself. **Why the previous attempt failed:** it never wrote the output file. This run creates `artifacts/` and writes `answer.json` into it.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It is untracked, and `git status` shows nothing to commit. - **Answer:** `848499000000000000` wei (0.848499 ETH). This is the floor for MAYC on OpenSea. I read it from `https://api.opensea.io/api/v2/collections/mutant-ape-yacht-club/stats` (`total.floor_price`). - **Timing caveat:** I read it about three minutes after the pinned closing block. The chain head was 26023203, 16 blocks past 26023187, and I had no historical listing data. The floor may have moved slightly since the pinned block. The answer's `definitions` and `notes` say this. - **Not consulted:** Blur and Magic Eden. - **Recipe:** it is the `panel` kind with that OpenSea URL as `source`, since the brief marks this question as panel evidence. - **Chain check:** I confirmed the closing block hash `0x407a32…` on `ethereum-rpc.publicnode.com`, which returned it for block 26023187. I did not check it on a second operator. - **Previous failures:** those attempts failed because the `artifacts/` directory did not exist. I created it before writing the file.
I wrote `artifacts/answer.json` with a floor price of **848499000000000000 wei** (0.848499 ETH). `check-answer.mjs` prints `ok`. The file is untracked, and `git status` shows nothing else changed. - **Source:** OpenSea's collection stats endpoint, `total.floor_price`. It needs no API key. Two reads seconds apart both returned 0.848499 ETH. The slug `mutant-ape-yacht-club` maps to contract `0x60e4d786628fea6478f785a6d7e704777c86a7c6` on Ethereum. - **Timing:** I read it at about 03:28 UTC on 2026-09-21. The chain head was block 26023201, 14 blocks (about three minutes) past the closing block 26023187, so the live floor stands in for the as-of-window floor. - **Chain check:** The pinned closing hash `0x407a3220…e058` matched on `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`, which are different operators. - **Recipe:** The question is a panel question, so the recipe is `panel` with the OpenSea stats URL as its source. `definitions` states the floor as the lowest active listing on OpenSea, with offers and bids excluded, and the denomination as wei of ETH. - **Fault from the earlier attempts:** The `artifacts/` directory didn't exist, which caused the ENOENT. I created it before writing the file. My first write also failed the check because `window` had its keys in a different order from the brief. I copied the brief's order. - **Limits:** OpenSea reports the floor to 6 decimals, so finer precision isn't available. I did not read Blur or Magic Eden. I can't reconstruct the exact listing state at the closing block's timestamp from the public API. All three caveats are in `notes`.
