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 The Captainz (Captainz, contract 0x769272677fab02575e84945f03eca517acc544cc) 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`; the checker prints `ok`. It records an OpenSea candidate of **33,401,700,000,000,000 wei** and explicitly documents that the historical floor and RPC-only reproduction remain unverified. The full acceptance criteria are therefore not satisfied.
`check-answer.mjs` prints **ok** (exit 0). `artifacts/answer.json` is written and left untracked. **Answer: 32990550000000000 wei** (0.03299055 ETH) What I did: 1. **Pinned the window first.** On `https://rpc.flashbots.net/fast` (`eth_chainId` → `0x1`), block 26023188 returned hash `0x6823bad2…fca579` — an exact match to the brief. Its timestamp is 2026-09-21T03:24:59Z; `fromBlock` 26022889 is 02:24:59Z, so the window is the hour that had just closed (head was 26023341). 2. **Read the fact.** This is an `"evidence": "panel"` brief, so the recipe is `{kind: "panel", source}` — the checker rejects any chain recipe here, and an NFT order book isn't in the on-chain logs anyway. OpenSea's floor for `memelandcaptainz` is **0.03299055 ETH**, retrieved 2026-09-21T03:56:34Z (32 min after the closing block, the nearest available reading), read via the public Alchemy NFT mirror and stable across two reads. ×10¹⁸ gives the wei figure exactly. 3. **Why OpenSea.** Of the three marketplaces the brief names, it's the only one readable without a private key: Blur's `core-api` sits behind a Cloudflare interstitial (403) and Magic Eden's Ethereum RTP API returns 400 for this collection. CoinGecko's lagging daily aggregate (0.034102 ETH) corroborates the magnitude but isn't a lowest-ask, so it isn't the cited figure; Alchemy's `getContractMetadata` floor is a July 2026 cache and was discarded. Two things worth flagging: - The acceptance line *"the recipe … reproduces the answer from public RPC data alone"* cannot hold for this brief — a floor price is off-chain, `evidence` is `panel`, and the checker enforces the panel recipe. I stated this in `notes` rather than forcing a chain recipe that would be refused. - OpenSea publishes only a live floor, not a floor at a past block. The 32-minute gap between the closing block and the reading is the main thing that could split honest panel members; the exact retrieval time is recorded in `definitions.asOf` and `notes`.

FAILURE: runtime_error
Completed `artifacts/answer.json` with the panel answer: `36900000000000000` wei from Blur’s The Captainz collection page. Verification run: `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` Result: `ok`
I could not find the Captainz floor price. `artifacts/answer.json` has `"answer": "0"` as a placeholder, and it is not a real floor. The file passes `check-answer.mjs` (it prints `ok`), but that only checks the format. - **Why no number:** OpenSea's API needs a key, the Reservoir host was unreachable, Magic Eden returned 400, and Blur returned nothing. Marketplace listings are off-chain, so no Ethereum RPC can reproduce them. I found no source for the floor at the closing block's time. - **How I flagged it:** the file uses a `panel` recipe with an OpenSea collection URL as the source. `definitions.answer_status` and `notes` both say the value is unmeasured and should be disregarded rather than read as a floor. - **What I did not run:** no on-chain scan, since none applies to this question. To get a real answer, someone needs an OpenSea, Blur or Magic Eden API key (or a historical listing snapshot) to read the lowest listing.
I wrote `artifacts/answer.json` and the checker prints `ok`. But the answer is not the floor the request defines: I couldn't read a listing directly from OpenSea, Blur or Magic Eden, so I used CoinGecko's figure instead. **Answer:** `34102000000000000` wei (0.034102 ETH). The recipe is `panel` with source `https://api.coingecko.com/api/v3/nfts/ethereum/contract/0x769272677fab02575e84945f03eca517acc544cc`. **Checks:** - **Closing block:** block 26023188's hash matches the one pinned in `oracle.json` on two endpoints, `ethereum-rpc.publicnode.com` and `rpc.mevblocker.io/fast`. Its timestamp is 2026-09-21T03:24:59Z. - **Wei figure:** 0.034102 × 10¹⁸ = 34102000000000000, checked with BigInt. - **File:** `check-answer.mjs` prints `ok`. It first rejected the file because the window's keys weren't in the same order as in `oracle.json`; I reordered them. **Why no marketplace listing:** - **OpenSea:** the API needs a key, and its collection page marks the slug `the-captainz` as a `DelistedCollection`. - **Magic Eden:** the v3 endpoints return "Not Found" and the v4 public endpoints return "no healthy upstream". - **Blur:** its API is behind a Cloudflare challenge. **Limits of this answer, also stated in `notes` and `definitions`:** - CoinGecko combines marketplace listings. It is not one of the named marketplaces, so this is not one listing read directly on a marketplace. - Its price is rounded to 6 decimal places of ETH. - I read it at about 03:54Z, roughly 29 minutes after the closing block. CoinGecko's price history, which would give the value at the closing block, is only on its paid plan. Other panel members who reach a real marketplace listing may get a slightly different number. The file is left untracked as instructed, and I changed nothing else.
Created [artifacts/answer.json](artifacts/answer.json); checker prints `ok`. The pinned historical floor remains unresolved. The file explicitly labels the observed OpenSea value as post-window and documents why it cannot satisfy RPC-only reproduction.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`, but the figure comes from an aggregator, not a marketplace listing. **Answer:** `34102000000000000` wei (0.034102 ETH), recipe kind `panel`. The chain-side checks passed: `eth_chainId` is 1, and block 26023188 has the pinned hash on both publicnode and flashbots RPC. Where the number comes from: - **Source:** CoinGecko's NFT API, `https://api.coingecko.com/api/v3/nfts/ethereum/contract/0x769272677fab02575e84945f03eca517acc544cc`, field `floor_price.native_currency`. It returned 0.034102 ETH. - **Not read from a marketplace:** you asked for the lowest active listing on a major marketplace, and I couldn't get one directly. - OpenSea's API needs a key, and its collection page marks `the-captainz` as `DelistedCollection` with no floor data. - Blur returns a bot challenge. - Magic Eden returns 403/404. - Reservoir no longer resolves in DNS. - **Not pinned to the window:** the reading is live, taken about 26 minutes after the closing block, not at its timestamp. `notes` and `definitions` in the file say all of this. If the panel agrees on a marketplace floor read with a key, that value should outweigh mine.
I wrote `artifacts/answer.json` with a floor of 34102000000000000 wei (0.034102 ETH), and `check-answer.mjs` prints `ok`. The number comes from CoinGecko, not from a marketplace listing. - **Source:** the CoinGecko NFT API, `https://api.coingecko.com/api/v3/nfts/ethereum/contract/0x769272677fab02575e84945f03eca517acc544cc`. I took `floor_price.native_currency` and multiplied by 1e18. - **Why not a marketplace:** OpenSea's API returned 401 without a key. Reservoir was unreachable. Magic Eden was behind a Cloudflare challenge. The OpenSea and Blur collection pages are rendered in the browser and carry no floor in their HTML. - **Rounding:** CoinGecko gives only 6 decimals of ETH, so the wei value is rounded to that. - **Timing:** I read the price when the chain head was about 130 blocks past 26023188. Live listings have no historical query without an API key. Other panel members may land on a slightly different figure. - **Chain check:** I confirmed block 26023188 exists on two endpoints from different operators (`rpc.flashbots.net/fast` and `ethereum-rpc.publicnode.com`). I did not compare the hash against the pinned one. - **Recipe:** it is the `panel` kind with the CoinGecko URL as `source`. These caveats are also in `definitions` and `notes`. The file is left untracked, as required.
Created [artifacts/answer.json](artifacts/answer.json); the checker prints `ok`. The task remains substantively incomplete: the file explicitly marks the observed OpenSea price as unverified for the pinned window. Historical off-chain listings cannot be reproduced from public RPC data alone.
Created `artifacts/answer.json`; checker prints `ok`. It records OpenSea’s observed 33,063,470,000,000,000 wei listing as an **unverified fallback**. The pinned-time floor and RPC-only reproduction could not be established; those limitations are explicit in the file.
I wrote `artifacts/answer.json` with a floor of 34102000000000000 wei (0.034102 ETH), and `check-answer.mjs` prints `ok`. The figure is CoinGecko's aggregated floor, not a lowest listing I read on a marketplace, so it may not match what the deployer reruns. - **Source:** the CoinGecko NFT API, `floor_price.native_currency`, cited as a `panel` recipe with that URL. I read it at about 03:48 UTC, roughly 23 minutes after block 26023188 (03:25 UTC). The floor could have moved in that gap. - **Marketplaces I couldn't read:** - OpenSea's public GraphQL returns `DelistedCollection` for `the-captainz`, so it shows no floor. - Blur and Magic Eden sit behind Cloudflare challenges or need API keys from this machine. - **Chain check:** the closing block hash matches the pin on `ethereum-rpc.publicnode.com`. I did not check it on a second operator's endpoint. - **Cross-check:** I did not verify the figure against a second source. The file's `notes` field states the timing gap and the aggregator caveat. The file is untracked and outside git, as required.
Created `artifacts/answer.json`; checker prints `ok`. The floor could not be verified. The file explicitly marks `0` as an unknown-value placeholder, not a price. The required panel recipe conflicts with RPC-only reproduction, so substantive acceptance criteria remain unmet.

Created `artifacts/answer.json`; the checker prints `ok`. The task remains incomplete: OpenSea’s observed listing began after the pinned close. The file explicitly records this limitation and the conflict between the required panel recipe and RPC-only reproduction.
I wrote `artifacts/answer.json` with a floor of **33292930000000000 wei** (0.03329293 ETH). `check-answer.mjs` prints `ok`. The figure is an OpenSea-only live read taken about 16 minutes after the pinned block. - **Source:** OpenSea's `memelandcaptainz` collection page, where the reported floor and the cheapest listing agree (native ETH, quantity 1). The `the-captainz` slug is delisted on OpenSea, so I used the slug that the OpenSea API returns for this contract. - **Recipe:** `panel` with that URL as the source, since the brief marks this as a panel-evidence question. - **Pin:** the closing block hash matched on `ethereum-rpc.publicnode.com` (block time 2026-09-21T03:24:59Z). `cloudflare-eth.com` errored, so there was no second-operator check. - **Timing:** no public historical listing archive exists, so I read the live listings at about 03:41Z rather than at the block time. The floor listings look like a bot that relists every 15 minutes with prices a few 1e-8 ETH apart. The exact wei at block time may therefore differ slightly from mine, and other panel members may land on slightly different figures. - **Marketplaces:** I could not read Blur (Cloudflare challenge) or Magic Eden (404 from its API), so a lower listing there can't be ruled out. The answer's `definitions` and `notes` state this. The other prices near 0.03 ETH that appear on the OpenSea page are last sales, so I excluded them.
Created `artifacts/answer.json`; checker prints `ok`. It records an OpenSea candidate of **33401690000000000 wei**, explicitly marked unverified. The historical floor and RPC-only reproduction remain unsatisfied: the required panel recipe depends on offchain marketplace data.
