Answer this question about chain 1 over blocks 26041409 to 26041705, exactly as .imd/reads/oracle.json pins it: What is the floor price of Hashmasks 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
I'll start by reading the task inputs.Now let me look at the check script and the imd-rpc skill.This is a panel-evidence question — the answer (OpenSea floor price of Hashmasks) lives off-chain, so the recipe must be `{"kind": "panel", "source": "<URL>"}`. First, let me pin down the closing block's timestamp via the private Ethereum node.Latest block is 26041761 — only ~56 blocks past the pinned closing block, so "as of the pinned window" means essentially now. The floor price is an off-chain OpenSea fact (panel evidence). Let me try to read it from OpenSea and fallbacks.The OpenSea API returned 200. Let me fetch the actual stats and the CoinGecko data.OpenSea's public API answers without a key. The stats endpoint reports a floor of 0.0894989 ETH. Let me cross-check with the best-listing endpoint, which is what the definition actually describes (lowest active listing, ETH/WETH payable).OpenSea's stats endpoint works unauthenticated and reports the collection's floor directly: 0.0894989 ETH for the verified `hashmasks` collection (contract `0xc2c747e0f7004f9e8817db2ca4997657a7746928`). The pinned closing block is ~56 blocks (~11 min) behind head, so a current read is as close to its timestamp as available. Converting: 0.0894989 ETH × 10¹⁸ = `89498900000000000` wei. Writing the answer.Key order in `window` must match the brief byte-for-byte (toBlock first). Fixing.Done. `check-answer.mjs` prints `ok`. Summary: - **Question**: panel-evidence (off-chain fact) — Hashmasks floor price on OpenSea, in wei, as of block 26041705. - **Source**: `https://api.opensea.io/api/v2/collections/hashmasks/stats` — reports `floor_price = 0.0894989 ETH` for the verified collection (`safelist_status: verified`, contract `0xc2c747e0f7004f9e8817db2ca4997657a7746928`). - **Timing**: chain head was 26041761 at read time, ~56 blocks (~11 min) past the pinned closing block — as close to its timestamp as available. - **Answer**: `89498900000000000` wei (0.0894989 ETH × 10¹⁸). - **Recipe**: `{ "kind": "panel", "source": "https://api.opensea.io/api/v2/collections/hashmasks/stats" }` — the only kind allowed for `"evidence": "panel"`. Deliverable: `artifacts/answer.json`.
Done. `artifacts/answer.json` passes the check (`ok`, exit 0) and is left untracked. **Answer: 89498900000000000 wei** (0.0894989 ETH) - **Kind:** `panel` — the brief sets `"evidence": "panel"`, so this is an off-chain fact and only the `panel` recipe is admissible; no chain recipe is rerun. - **Pin verified:** block 26041705 → hash `0xc20d4f80…f8e578`… matches on two independent endpoints (the configured keyed Ethereum route and `https://ethereum-rpc.publicnode.com`). Its timestamp is 1790184995 = 2026‑09‑23T17:36:35Z, i.e. the window closes at read time, so a live read is the correct reading per the `time` definition. - **Source:** `https://api.opensea.io/api/v2/listings/collection/hashmasks/best` — cheapest active ETH listing is exactly 89498900000000000 wei. Cross-checked against the collection `stats` endpoint, which reports `floor_price` 0.0894989 ETH — identical. - **Collection resolved:** slug `hashmasks`, `safelist_status: verified`, single mainnet contract `0xc2c747e0f7004f9e8817db2ca4997657a7746928`. - **Definitions stated and used:** collection identity, floor as lowest active ETH/WETH listing, wei denomination (exact integer listing value rather than the rounded ETH float), time-of-read, and the missing-listing case (not applicable — many active ETH listings). One judgment call worth flagging: the brief's `window` is context only for this question type, so the block range constrains *when* the floor is read, not a range of data aggregated over it.

Check passes (`ok`). Wrote `artifacts/answer.json` as a panel-evidence answer: Hashmasks floor price read from OpenSea's Collection Stats API (0.0894989 ETH = 89498900000000000 wei), with the pinned window/request id copied exactly and the block hash confirmed via public RPC.
Wrote `artifacts/answer.json` — Hashmasks floor price read from OpenSea (https://opensea.io/collection/hashmasks): 0.0894989 ETH = 89498900000000000 wei, using a `panel` recipe as required for this off-chain evidence question. `check-answer.mjs` passes with `ok`. Note: OpenSea only exposes the current live floor, not a historical point-in-time snapshot at block 26041705, so this is the closest honest reading available and I flagged that limitation explicitly in `notes`.
Check passes. I confirmed the pinned block hash on a live RPC (block 26041705 timestamped 2026-09-23T17:36:35Z, essentially "now"), then read OpenSea's public collections stats API for the Hashmasks collection floor price (0.0894989 ETH), converted to wei, and wrote `artifacts/answer.json` with the `panel` recipe citing that source. `check-answer.mjs` prints `ok`.

The check passes with `ok`. **Summary:** Answered the panel question with Hashmasks' OpenSea floor price at the pinned window. Confirmed block 26041705's timestamp (2026-09-23T17:36:35Z) via `eth_getBlockByNumber`, verified the collection (contract `0xc2c747e0f7004f9e8817db2ca4997657a7746928`, safelist-verified) via OpenSea's collections API, and read the floor price (0.0894989 ETH → 89498900000000000 wei) from `https://api.opensea.io/api/v2/collections/hashmasks/stats`. Wrote `artifacts/answer.json` with the `panel` recipe citing that source, and `check-answer.mjs` reports `ok`.

I wrote `artifacts/answer.json` with a Hashmasks floor of 89498900000000000 wei (0.0894989 ETH), and the check script prints `ok`. The value is the live floor at the time I read it, not the floor at the pinned closing block's timestamp. I read it from the OpenSea stats endpoint for the `hashmasks` slug (`total.floor_price`) and multiplied by 1e18. OpenSea only serves the current floor, so I couldn't read it as of the closing block. I stated this under `definitions` and in `notes`. The recipe kind is `panel`, as the request requires, with the OpenSea URL as its source. The window, request id and chain are copied from `.imd/reads/oracle.json`. No RPC was used, so the closing block hash was not confirmed against an endpoint.

The Hashmasks floor price on OpenSea is **89498900000000000 wei (0.0894989 ETH)**. I've written it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for the file. One caveat: I read the price about 8 minutes after the closing block, not at it. OpenSea only shows the current floor, so I couldn't look it up as of that block. Block 26041705 was at 2026-09-23 17:36:35 UTC and I read the page at about 17:44 UTC. The floor could have changed in that gap, and the notes in the answer say so. - **Block:** the closing block's hash on `ethereum-rpc.publicnode.com` matches the one pinned in the request. - **Collection:** the right one is OpenSea's `hashmasks`. It is verified and uses contract `0xc2c747e0f7004f9e8817db2ca4997657a7746928`, with about 5,144 owners and 104 items listed. Two unverified copies, `thehashmasks` and `the-hashmasks`, have one owner and no listings, so I left them out. - **Source:** OpenSea's API needs a key, so I read the floor from the public page `https://opensea.io/collection/hashmasks`. The lowest listing is 0.0894989 ETH, paid in plain ETH, which converts to 89498900000000000 wei. The recipe is `{kind: "panel", source: "https://opensea.io/collection/hashmasks"}`. - **Definitions:** time, floor, collection and missing are all stated in the file. "Missing" didn't apply because the collection had active ETH listings. `artifacts/answer.json` is untracked, as required.
Check passes. `artifacts/answer.json` reports the Hashmasks OpenSea floor at the pinned block's timestamp (essentially the present moment, verified against the pinned block hash) as 0.0894989 ETH = 89,498,900,000,000,000 wei, using a `panel` recipe citing the OpenSea collection page as source.
check-answer.mjs prints `ok`. artifacts/answer.json is complete: floor price = 89498900000000000 wei (0.0894989 ETH), sourced from OpenSea's public stats API, with the pinned window and block hash confirmed via RPC.
Check passes. The answer file is written at `artifacts/answer.json`: Hashmasks floor price = 89,498,900,000,000,000 wei (0.0894989 ETH), sourced from OpenSea's collection stats endpoint, with the closing block hash confirmed via public RPC.
I wrote `artifacts/answer.json` with a floor of 89498900000000000 wei (0.0894989 ETH), and `check-answer.mjs` prints `ok`. The value is a live reading taken a few blocks after the pinned closing block, not the floor at block 26041705 itself. - **Source:** the `total.floor_price` field from OpenSea's v2 stats endpoint for the `hashmasks` collection, `https://api.opensea.io/api/v2/collections/hashmasks/stats`. The recipe is `panel`, as the brief requires for an off-chain fact. - **Timing:** when I read it the chain head was about block 26041737, seconds past the pinned close. OpenSea offers no historical floor, so the value could have drifted slightly from the true floor at the pinned block. I noted this in `notes`. - **Not checked:** I didn't run the scan script, since a panel answer has no chain recipe to rerun. I did not separately confirm the pinned block hash against an RPC. I only checked the chain head on `ethereum-rpc.publicnode.com`.
I wrote `artifacts/answer.json` with a floor of 89498900000000000 wei (0.0894989 ETH), and `check-answer.mjs` prints `ok`. This is today's floor, not the floor at block 26041705. I read it live from the OpenSea collection page for Hashmasks (`https://opensea.io/collection/hashmasks`), which only shows the current listing, and I couldn't get a historical value at the closing block. The answer file's `definitions` and `notes` say so. I also never checked the pinned closing block hash against an RPC. My one block lookup was at a wrongly converted block number, so it confirmed nothing. The recipe is `panel` with that URL as the source, since the request is marked `"evidence": "panel"`.
I wrote `artifacts/answer.json` with a Hashmasks floor of 89498900000000000 wei (0.0894989 ETH), and `check-answer.mjs` prints `ok` for it. - **Source:** the OpenSea v2 stats endpoint for the `hashmasks` collection (`https://api.opensea.io/api/v2/collections/hashmasks/stats`). Its `floor_price` field read 0.0894989 ETH, which I multiplied by 1e18. - **Not tied to the pinned block:** that endpoint only gives the floor at the time I fetched it. It has no history, so I could not read the floor as of block 26041705. The answer file says this in `definitions` and `notes`. - **Recipe:** it is `panel`, since the request's evidence type is `panel`. It names that OpenSea URL as the source, so no chain scan was run. - **Checks skipped:** I did not confirm the pinned block hash on an RPC endpoint. I also did not check that Hashmasks is the verified collection on OpenSea, or that this floor is an ETH/WETH listing.
I wrote `artifacts/answer.json` with a Hashmasks floor of `89498900000000000` wei (0.0894989 ETH). This is the current floor at run time, not the floor at the pinned closing block. `check-answer.mjs` prints `ok`. - **Source:** OpenSea's public v2 collection stats endpoint for the `hashmasks` slug, `https://api.opensea.io/api/v2/collections/hashmasks/stats`. It needed no key and returned `floor_price` 0.0894989 ETH. - **Recipe:** `panel` with that URL as the source, since the request's evidence type is `panel`. - **Not verified:** OpenSea only exposes the current floor, so I could not check the floor at the closing block's timestamp. The `time` definition and `notes` say so. - **Not done:** I did not confirm the pinned block hash on an RPC. My one `eth_getBlockByNumber` call on `ethereum-rpc.publicnode.com` returned `null`, possibly because I typed the block number in hex wrongly, and I didn't retry it.
I wrote `artifacts/answer.json` with a Hashmasks floor of 89498900000000000 wei (0.0894989 ETH), and `check-answer.mjs` prints `ok` for it. The figure is the live reading, not the value at block 26041705. I took `total.floor_price` from `https://api.opensea.io/api/v2/collections/hashmasks/stats` when I ran this. The request asks for the floor as of the closing block's timestamp, and I couldn't get a historical value from that endpoint. The answer's `notes` and `definitions` say so, and the recipe is the `panel` kind with that URL as its source. I did not check the closing block hash against an RPC endpoint. My one RPC call, to publicnode, used the wrong block number (a hex typo), so it confirmed nothing. The pinned hash in the file is copied from `.imd/reads/oracle.json`.
I wrote `artifacts/answer.json` with a Hashmasks floor of 89498900000000000 wei (0.0894989 ETH). `check-answer.mjs` prints `ok` on it. The number is OpenSea's floor at the time I ran this, not at the pinned closing block. I fetched it from OpenSea's collection stats API for the `hashmasks` slug (`total.floor_price`) and converted it to wei. The API only gives the current floor, so I couldn't read it at the closing block's timestamp. The notes and definitions in the file say this.

The check passes. I answered the Hashmasks floor-price question as a panel-evidence recipe: confirmed the pinned block hash/timestamp matched present time (2026-09-23 17:36:35 UTC), read the OpenSea collection page twice for consistency (0.0894989 ETH), converted to 89498900000000000 wei, and wrote `artifacts/answer.json`, which `check-answer.mjs` validates as `ok`.

Check passed (`ok`). `artifacts/answer.json` reports the Hashmasks OpenSea floor price at the pinned window as 89,498,900,000,000,000 wei (0.0894989 ETH), via the `panel` recipe sourced from opensea.io/collection/hashmasks — the pinned block's timestamp is essentially now, so the live OpenSea floor was directly representative.
I wrote `artifacts/answer.json` with a Hashmasks floor of 89498900000000000 wei (0.0894989 ETH). The answer check prints `ok`. The figure comes from OpenSea's collection stats endpoint for the `hashmasks` slug (`https://api.opensea.io/api/v2/collections/hashmasks/stats`), and the recipe is `panel` with that URL as the source. **Not read at the pinned block:** the floor is what OpenSea reported when I fetched it, not the value at the pinned closing block's timestamp. The API only serves the current figure and I found no historical one. I said this in `definitions` and `notes`. If other panel members read the floor at a different moment, their answers may not match this one. I did not check the block hash on an RPC endpoint, because this recipe is not a chain scan and nothing is rerun.

The value is the live floor, not the floor at the pinned block. I read `total.floor_price` from OpenSea's public collection stats endpoint (`https://api.opensea.io/api/v2/collections/hashmasks/stats`), which only serves the current floor. The pinned closing block's timestamp is therefore not reflected in the answer. I said this in `notes` and in `definitions`. The question is marked as a panel question, so the recipe is `panel` with that URL as the source. No chain scan was run, and I didn't check that "hashmasks" is the verified collection with the largest market cap.

The figure comes from OpenSea's collection stats endpoint (`https://api.opensea.io/api/v2/collections/hashmasks/stats`, `floor_price`). This is a panel question, so the recipe is `panel` with that URL as the source. Nothing was scanned on-chain. It is a live read, not the floor at the pinned closing block. OpenSea's stats endpoint gives only the current floor, so the value can differ from what other panel members read at other times. I noted this in `notes` and in `definitions`. I did not separately check that the floor listing is priced in ETH or WETH, as the definitions require.

The number comes from `total.floor_price` in the OpenSea stats API for the `hashmasks` collection, multiplied by 1e18. The recipe is `panel` with that URL as its source. The reading is live, not taken at the pinned closing block. OpenSea's API gives no historical floor, so the floor at that block's timestamp may differ. I said this in `definitions` and `notes`. I did not run any RPC scan, since this is an off-chain fact and no chain recipe applies.
