Answer this question about chain 1 over blocks 26021176 to 26021473, exactly as .imd/reads/oracle.json pins it: What is the floor price of Lil Pudgys on Ethereum mainnet, in wei, as of the pinned window? 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` with the observed floor: **313978000000000000 wei**. JSON validation passed. The artifact explicitly records that the pinned historical floor and RPC-only reproducibility remain unverified; it does not satisfy those acceptance criteria.
I wrote `artifacts/answer.json` with a floor price of **313986000000000000 wei** (0.313986 ETH). It rests on a single source, so it is less firmly backed than I'd like. - **Source:** OpenSea's public stats API, `total.floor_price`. I checked that the `lilpudgys` slug maps to contract `0x524cab2e…a048` on Ethereum. - **Recipe:** the question is marked panel evidence, so the recipe is `panel` with that URL as `source`. - **Window and block:** the request id, chain and window are copied from the pinned request. Two independent RPCs (publicnode and Flashbots) returned the same closing block hash. The block's timestamp is 2026-09-20 21:39:59 UTC. - **Timing gap:** the listings API only shows current state. I read the floor at about 22:31 UTC, roughly 51 minutes after the closing block, and got the same value on both reads. Other panel members could see a slightly different floor if listings moved. I noted this gap in `notes` and `definitions`. - **Blur not covered:** Blur returned 403, so the floor covers OpenSea and its Seaport-based listings only. Reservoir was unreachable, CoinGecko returned no data and OpenSea's listings endpoint needs an API key, so none of them could cross-check the figure. The file is untracked, and I wrote nothing else.
`artifacts/answer.json` is written, valid JSON, untracked, and the only path touched. **Answer: `315666000000000000` wei (0.315666 ETH)** How it was computed: - **Window verified** on two operators' RPCs (flashbots, publicnode): chain id `0x1`, block 26021473 hash `0x5246be01…e403`, timestamp 2026-09-20T21:39:59Z. - **Primary source** (the `panel` recipe's `source`): `https://api.opensea.io/api/v2/collections/lilpudgys/stats`, read at 2026-09-20T22:21:39Z → `floor_price` 0.315666 ETH. OpenSea maps that slug to `0x524cab2ec69124574082676e6f654a18df49a048`. - **Cross-checks**: Alchemy NFT API (OpenSea field) 0.315674 @22:20:23Z; NFTPriceFloor 0.315705 @22:09:37Z, reporting OpenSea as the origin of the lowest listing across marketplaces (including Blur); CoinGecko 0.315696. Blur's API sits behind a Cloudflare challenge and OpenSea's raw-listing endpoints need a key, so the wei value comes from the stats floor — which is 6-decimal ETH across three independent readers, so no rounding. One caveat, stated in `notes`: the floor was being undercut by bots in 1e-6 ETH steps during the reading period (0.315675 → 0.315674 → 0.31567 → 0.315666 within two minutes), and the value at exactly the closing block (~42 min earlier) cannot be reconstructed from public data (only 2-hour history buckets exist). Panel members reading at different seconds will land on values a few thousand gwei apart; I reported the latest primary-source reading with its time, as the definition requires.
Created and validated [artifacts/answer.json](/root/.identitymd/work/36ddb7de-cd05-43a8-ab31-1fb89a4807ec/f7c5486b-1530-4767-a262-6a375b9f747c/artifacts/answer.json). Answer: `315683000000000000` wei.
I verified the pinned closing block on chain (hash and timestamp match), confirmed the contract, and read the Lil Pudgys floor price from OpenSea's public stats API (0.315715 ETH), cross-checked against the NFTPriceFloor aggregator (0.315734 ETH, same underlying OpenSea source). Wrote `artifacts/answer.json` with a `panel` recipe, answer `315715000000000000` wei, and notes documenting both readings and the endpoints used.
Done. `artifacts/answer.json` is written (untracked, excluded by `.git/info/exclude` — not force-added). **Answer: `315797000000000000` wei** (0.315797 ETH) — Lil Pudgys floor. **What I did** - **Window verified first.** `eth_getBlockByNumber(0x18d0e61)` returned hash `0x5246be0…a0e403` and timestamp `1789940399` (2026-09-20T21:39:59Z) *identically* on three independent operators — `rpc.flashbots.net/fast`, `rpc.mevblocker.io/fast`, `ethereum-rpc.publicnode.com`. Matches the pinned `toBlockHash` exactly. The window is the ~59 minutes ending 21:39:59Z. - **Floor read.** The brief is `"evidence": "panel"`, so per the catalogue only the `panel` recipe applies — an NFT floor lives off chain and no chain recipe yields it. Source: CoinGecko's cross-marketplace NFT endpoint for contract `0x524cab…a048`, `floor_price.native_currency = 0.315797 ETH`. Read three times (21:52Z, 21:55Z, 21:56:17Z) — identical each time, 16 minutes after the closing block. Converted with BigInt string arithmetic, not floats. - **Internal consistency check:** the same payload's `market_cap.native_currency / total_supply` = 6925.74 / 21931 = 0.3158 ETH, and it reports a live −8.17% 24h move on 16.69 ETH volume, so the feed is moving rather than frozen. **What I could not do, stated plainly** - OpenSea (401, key required), Blur (Cloudflare challenge), LooksRare (404 behind Cloudflare), Reservoir, Magic Eden RTP and nftpricefloor all refused unauthenticated requests from this container. So I could not read the primary marketplace orderbooks directly; the answer rests on one aggregator's cross-marketplace minimum. - **DefiLlama disagrees**: it reports 0.85687 ETH for the same contract, but with `floorPricePctChange1Day` exactly `0` — a stale feed. I rejected it rather than averaging, and recorded the discrepancy in `notes` instead of hiding it. - This is an aggregator floor sampled 16 min *after* the close, not a wei-exact lowest listing reconstructed at block 26021473. That caveat is written into `definitions` and `notes`, so a reviewer sees the limit of the figure. Structural checks all pass: requestId/chain/window copied exactly, hash lowercase, `uint256` as a decimal string, recipe is `panel` with exactly `kind` + `source` (a URL) and nothing else.
Created and validated `artifacts/answer.json` with observed fallback **315761000000000000 wei**. The file explicitly documents that this quote postdates the pinned window and cannot satisfy RPC-only historical reproduction. The requested floor remains unverified.
Created and validated `artifacts/answer.json` with the observed floor: **315780000000000000 wei**. The file explicitly documents the limitation: this marketplace observation cannot establish the exact historical floor or satisfy RPC-only reproduction.
