Answer this question about chain 1 over blocks 26022889 to 26023188, exactly as .imd/reads/oracle.json pins it: What is the floor price of DeGods (DeGods, contract 0x8821bee2ba0df28761afff119d66390d594cd280) 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
`artifacts/answer.json` is written (3,613 bytes, git-ignored so it stays untracked), and `check-answer.mjs` prints `ok`. ## Answer **175204990000000000 wei (0.17520499 ETH)** — lowest active listing on **OpenSea** (slug `degods-eth`, DeGod #7495 / tokenId 7494), read at 2026-09-21T03:30:40Z, the earliest reading after the closing block. ## How it was computed - **Window pinned**: block 26023188 hash `0x6823bad2…fca579` confirmed on two operators (flashbots, publicnode); mined at 03:24:59Z. Head was only ~72 blocks past it, so the window is live. - **Read**: `https://api-bff.nftpricefloor.com/projects/degods` → `floorInfo {currentFloorNative: 0.17520499, origin: opensea, tokenId: 7494, latestFloorTs: 03:30:40Z}`. Answer = that × 1e18 exactly (native-ETH listing, no fiat conversion). - **Corroboration**: at 03:45:49Z the same endpoint reported 0.17391 ETH, identical to OpenSea's own page payload rendered at 03:45:47Z (`floorPrice.token.unit: 0.17391`, native ETH, a Blur listing aggregated by OpenSea) — so the endpoint relays exact OpenSea listing prices rather than a USD-derived estimate. ## What you should know - **The floor is bot-driven and drifting.** The four cheapest listings are all bots posting 15-minute native-ETH orders and undercutting each other by ~1e-6 ETH every minute (0.17520 → 0.17456 → 0.17436 → 0.17406 → 0.17391 over 03:30–03:46Z). Since those are off-chain orders that expire and get replaced, the exact wei active at 03:24:59Z is not retrievable after the fact; I reported the earliest post-close reading (5m41s later). The lowest non-bot listing (0.1887 ETH, live since Sep 16) is well above the bot floor, so it is not the floor. Panel members reading at different minutes will get slightly different values — this is inherent to the question, and it's stated in `notes`/`definitions`. - **Coverage**: OpenSea (which aggregates Blur listings) was read directly; Blur's own API and Magic Eden's EVM API were unreachable (Cloudflare challenge / removed routes), OpenSea REST needs a key, and the marketplace pages 403 plain fetches — I rendered OpenSea through r.jina.ai to read its RSC payload.
Done. `artifacts/answer.json` exists and `check-answer.mjs` prints `ok`. **What I did** 1. **Pinned the window first.** `eth_getBlockByNumber(0x18d1514)` on `eth.drpc.org` and `ethereum-rpc.publicnode.com` both returned the brief's hash `0x6823bad2…fca579`, timestamp `2026-09-21T03:24:59Z`. Opening block 26022889 is `02:24:59Z` — a one-hour window that closed ~20 min before I read. 2. **Resolved contract → collection.** `api.opensea.io/api/v2/collections/degods-eth` lists exactly one contract, `0x8821bee2…cd280` on ethereum, name DeGods, supply 3098 — so the slug and the question's contract are the same collection. 3. **Read the floor.** `api.opensea.io/api/v2/collections/degods-eth/stats` → `floor_price: 0.17391 ETH`, identical on two fetches minutes apart. **0.17391 ETH = 173910000000000000 wei.** 4. **Cross-checked from an independent operator.** Alchemy's `getFloorPrice` returned the same `openSea.floorPrice: 0.17391`, retrieved `03:45:52Z`. **Limits, stated in the answer rather than papered over** - Of the three named marketplaces, only OpenSea was readable here: Blur's core-api returned 403 (Cloudflare) and Magic Eden's EVM RTP returned 400 without a key. If a panel member reads a strictly lower active ask on Blur or Magic Eden, that is the better answer under the request's own definition — the `definitions` block says so. - CoinGecko reports 0.17491 ETH. That's an aggregator with its own refresh lag, not an orderbook, so I used the marketplace's API and recorded the 0.001 ETH gap in `notes`. - The orderbook is off-chain and not queryable at a historical block, so the value is a live read minutes past the close; the collection had 0 sales in the prior 24h, which is why I treat it as stable across the window. That assumption is in `definitions.as_of`. Recipe is `{ kind: "panel", source: "https://api.opensea.io/api/v2/collections/degods-eth/stats" }`. File is 4447 bytes, notes 2822 chars, left untracked.
Created `artifacts/answer.json`; checker prints `ok`. Recorded OpenSea’s observed floor as `174109000000000000` wei. The file explicitly notes that the historical floor remains unverified and the required panel recipe cannot reproduce it from RPC data alone.
Created `artifacts/answer.json`; the checker prints `ok`. It records OpenSea’s observed **174358000000000000 wei**, with explicit limitations: the pinned historical floor and RPC-only reproduction could not be verified. The answer is not suitable for attestation as a verified historical result.
Created `artifacts/answer.json`; checker prints `ok`. It records OpenSea’s latest observed floor, `174458000000000000 wei`. Notes explicitly mark it unverified at the pinned time and explain why the required panel recipe cannot satisfy RPC-only reproduction.
`artifacts/answer.json` is written and the checker prints `ok`. ## What I did **Pin confirmed first.** `eth_chainId` = 1 and `eth_getBlockByNumber(26023188)` = `0x6823bad2…fca579` on three independent operators (flashbots, publicnode, mevblocker). Closing block timestamp 1789961099 = 2026-09-21T03:24:59Z. An `eth_call` at that block on the pinned contract returns `name() = DeGods`, `symbol() = DEGODS`, so the address in the question is the collection. **The figure.** This is an `"evidence": "panel"` brief — an off-chain order book — so the recipe is `{ kind: "panel", source }`. OpenSea's own GraphQL API (`https://gql.opensea.io/graphql`) answers without a key; `collectionBySlug(slug: "degods-eth")` resolves to the pinned contract and reports `floorPrice.pricePerItem.token` = `{ unit: 0.17491, symbol: "ETH", address: 0x0…0 }`. That is **0.17491 ETH = 174910000000000000 wei**. Cross-checked from the item side: the three cheapest live asks were 0.174859 (OpenSea), 0.17486 (Blur), 0.17490099 (OpenSea) — OpenSea's aggregation carries Blur, so the collection floor and the cheapest ask agree to within 0.00005 ETH. ## What the answer can't claim, and why (stated in `definitions`) - **No historical order-book state exists anywhere.** Listings are signed Seaport/Blur orders that never touch chain; OpenSea exposes no floor time series; Reservoir has shut down, so neither `api.reservoir.tools` nor the Magic Eden RTP proxy resolves — Magic Eden could not be read at all. The reported value is the **earliest reading I could take after the closing block** (~03:32Z, ~7 min later), not a reconstruction of 03:24:59Z. - **The book churns fast.** The cheapest listings carry 15-minute expiries and bots relist a few 0.00001 ETH lower every ~30s: I sampled 0.174759 → 0.174709 → 0.17466 → 0.174659 ETH across 03:35:57–03:37:12Z, about −0.00008 ETH/min. I reported the reading **unrounded** and documented the drift rather than inventing a rounding rule; a panel member reading at a different minute will land on a slightly different wei value, and that is a property of the question, not of the reading. Rejected sources, recorded in `notes`: CoinGecko (0.182469 ETH — a lagging aggregator, not an order book), DefiLlama (floor data stops 2025-10-24), OpenSea REST v2 and Alchemy NFT (both key-gated here), Blur's own API (Cloudflare challenge).
Created `artifacts/answer.json`; checker prints `ok`. It records **174558000000000000 wei** as an explicitly unverified live observation. The pinned historical floor and RPC-only reproducibility remain unresolved; those limitations are documented in the file.
I wrote `artifacts/answer.json` with a DeGods floor of 174659000000000000 wei (0.174659 ETH). `check-answer.mjs` prints `ok`. The file is untracked and nothing else changed. - **Source:** OpenSea API v2 collection stats for `degods-eth`, field `total.floor_price`. The collection's contract list on OpenSea matches `0x8821bee2ba0df28761afff119d66390d594cd280`. - **Timing caveat:** this is a live reading, not a snapshot at the pinned block. I read it about 13 minutes after the closing block's timestamp (2026-09-21 03:24:59 UTC). OpenSea offers no historical floor without an API key. The 24-hour volume was 0, so the floor most likely hadn't moved. `notes` says this too. - **Other marketplaces:** Blur and Magic Eden returned nothing usable without a key. The answer rests on OpenSea alone. - **Chain check:** block 26023188 on `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast` returned the pinned hash `0x6823bad2…fca579`. - **Recipe:** it is a `panel` recipe naming the OpenSea stats URL as its source, because this brief is off-chain evidence. - **Earlier failure:** the last attempt failed because the `artifacts/` directory didn't exist. I created it this time. - **Format fix:** the checker also rejected my first draft for writing the `window` keys in a different order than the brief. I reordered them to match.
I wrote `artifacts/answer.json` with a floor of 0.174659 ETH (174659000000000000 wei), and `check-answer.mjs` prints `ok`. It is a live OpenSea read from about 12 minutes after the pinned close, not a reconstruction at the pinned block. The file is ignored by git, so nothing needs committing. **What failed last time:** `artifacts/` didn't exist. I created the directory before writing the file. **How I got the number:** - **Recipe kind:** the brief sets `"evidence": "panel"`, so the recipe is `panel`. The source is OpenSea's `https://api.opensea.io/api/v2/collections/degods-eth/stats`, field `floor_price`. - **Contract match:** I checked that the slug `degods-eth` lists contract `0x8821bee2ba0df28761afff119d66390d594cd280` on Ethereum. - **Chain and hash:** chain 1 and the pinned closing hash for block 26023188 matched on `rpc.flashbots.net/fast` and `ethereum-rpc.publicnode.com`. That block is 2026-09-21 03:24:59 UTC. - **Conversion:** I converted the decimal string to wei exactly. I did not run the scan script, since a panel question has no chain scan to run. **Caveats, also in `notes` and `definitions`:** - **Floor drift:** the floor moved between reads: 0.174709, 0.174659 and 0.174607 ETH within a few minutes. Panel members reading at other moments will differ in the 4th to 6th decimal, so exact agreement is not guaranteed. - **Rounding:** the API serves 6 decimals, so the wei figure is only precise to 10^12 wei. - **Not point-in-time:** OpenSea has no historical floor endpoint. - **OpenSea only:** the per-listing endpoint needs an API key I don't have, so I couldn't read the cheapest listing's exact price. Reservoir was unreachable, and I didn't read Blur or Magic Eden.
Wrote `artifacts/answer.json` with the DeGods floor answer: `165200000000000000` wei from OpenSea (`0.1652 ETH`). Verification passed: ```text node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json ok ```
I wrote `artifacts/answer.json`, and the answer checker prints `ok` for it. The DeGods floor is **174709000000000000 wei (0.174709 ETH)**, read from OpenSea. - **Source:** OpenSea's public collection stats (`https://api.opensea.io/api/v2/collections/degods-eth/stats`), which gave a floor of 0.174709 ETH. I read it twice and got the same value both times. OpenSea's collection record confirms that slug `degods-eth` is contract `0x8821bee2ba0df28761afff119d66390d594cd280` on Ethereum. - **Window:** the closing block 26023188 has the pinned hash on two endpoints from different operators (publicnode and mevblocker). It was mined at 2026-09-21 03:24:59 UTC. I read the floor about 12 minutes later, not at that exact time. The collection had no sales in the past day, so the floor was probably the same at closing. - **Not the individual listing:** OpenSea needs an API key to show the single best listing, so I couldn't see its exact wei price. The answer takes the stats floor of 0.174709 ETH as exact. - **Other marketplaces:** Magic Eden's API returned "Not Found" and I didn't try Blur, so the answer uses OpenSea only. - **Recipe:** it is `panel` with the OpenSea URL as `source`, since this question takes panel evidence. The definitions state the floor, the wei denomination, the source and the ETH-to-wei conversion. - **Last attempt's failure:** the previous run failed because the `artifacts/` directory was never created. This time I created it and wrote the file. Git doesn't show the file as changed, so it is untracked (probably ignored) and was not committed.

Created `artifacts/answer.json`; the checker prints `ok`. The file records an observed OpenSea quote and explicitly flags it as unverified for the pinned time. The RPC-only requirement conflicts with the required `panel` recipe, so historical-price acceptance remains unmet.
I've written `artifacts/answer.json`, and the plane's `check-answer.mjs` prints `ok` for it. **Answer:** 175310000000000000 wei (0.17531 ETH), a `panel` recipe with source `https://api.opensea.io/api/v2/collections/degods-eth/stats`. The floor comes from OpenSea's public stats endpoint, which needs no API key. It returned a `floor_price` of 0.17531 ETH, the same on two reads. The collection endpoint confirms the slug `degods-eth` is DeGods (verified), and its only contract is `0x8821bee2ba0df28761afff119d66390d594cd280` on Ethereum. **Limits you should know about:** - **Timing:** I read the floor about 5 minutes after the closing block, not at it. The block closed at 03:24:59 UTC; I read around 03:30 UTC, when the chain was 24 blocks past it. OpenSea has no public endpoint for the floor at a past moment, so I'm treating this reading as the floor at the closing block. The notes say so. - **Not the individual listing:** OpenSea's endpoint for the actual lowest listing needs an API key, so I have the collection floor figure but not the specific order behind it. - **No second marketplace:** Blur's API was behind a bot check, and the Magic Eden endpoint I tried returned "Not Found". Only OpenSea stands behind this number. **Window:** I confirmed the pinned closing block hash on two separate public nodes (publicnode.com and drpc.org). The request id, chain and window are copied exactly from `oracle.json`. `artifacts/answer.json` is the only file I wrote. It is untracked and not committed.
Created [artifacts/answer.json](artifacts/answer.json); checker prints `ok`. It records OpenSea’s observed floor of **175310000000000000 wei**, explicitly unverified at the pinned close. The historical-price and RPC-only reproduction requirements remain unmet; the required `panel` recipe cannot provide RPC reproduction.
