# 404KIN FIELD

10,000 deterministic geometric artworks on Ethereum. Public mint was observed open at 0.001 ETH plus gas, up to two per recipient. Terms are snapshots; re-read current chain state before deciding or signing. Source-art catalog entries do not reserve a token or trait. Individual V4.1 artwork was revealed on 18 September 2026. Minted token IDs 1 and 2 were checked against their original metadata and SVGs; see [dated reveal evidence](/api/nft/v4-1/reveal.json). The 10,000 cap is unchanged.

## Access verification and fallback

Default Node.js 24 fetch retrieved this site's llms.txt anonymously with HTTP 200 on 2026-09-18 at 05:18:48 UTC. The separate public tools service also passed 14 anonymous live checks. Earlier Python urllib retrieval returned HTTP 403/Cloudflare 1010 and remains an unresolved client-specific compatibility issue. No custom User-Agent, credentials, cookies or bypass token was used for Node verification; no universal client or availability guarantee. Do not bypass a security challenge.

Official OpenSea REST drop lookup and one unsigned mint construction returned HTTP 200 on 2026-09-18; the decoded public-mint core fields matched. See [verification scope](/agents/api-verification.json). This does not establish simulation, gas, all-wallet eligibility, signature or broadcast success, and is separate from the client-specific website and tool-access tests. Re-read live terms before signing.

- [Tool verification](/agents/tool-verification.json): 14 anonymous live checks, synthetic operator tests only.
- [Machine entry](/agents/agent.json): exact contracts, dates, price, route scope and timestamped observations.
- [Mint integration](/agents/MINT_GUIDE.md): buyer-controlled public mint, eligibility checks and separate signed-route caveats.
- [API information](/agents/api-integration.json): direct SeaDrop and optional OpenSea API paths; no credentials or automatic signing.
- [Artwork catalog](/agents/catalog/index.json): 10,000 source records in 100 pages.
- [Trait index](/agents/trait-index.json): eight dimensions; no selectable primary-mint traits.
- [Artwork previews](/previews.json): six real source-art examples and hashes.
- [Rights and hosting](/agents/RIGHTS_AND_HOSTING.md): collectible-art scope and delivery limits.
- [Official sources](/agents/SOURCES.md).

No financial return, agent service or guaranteed independent demand. A successful mint from a project-funding-associated wallet proves a purchase path, not an independent AI buyer. Each buyer is responsible for its owner's authorization and transaction review.

## Free studio study

[80/20: The Shape of Concentration](/studies/pareto/) is one shared Pareto-model artwork with [parameters](/studies/pareto/model.json) and [method](/studies/pareto/method.md). It uses no market data, is free to view without minting, has no assigned token ID and does not replace the V4.1 edition or alter mint delivery or rights. An 80/20 distribution was deliberately calibrated; it is not observed wealth or a return forecast.

## Free report trial

[FIELD Report](/tools/field-report/) exposes a limited free POST endpoint for 2–16 caller-supplied simple returns. [API contract](/tools/field-report/api.json). It produces approximate binary64 JSON metrics and SVG; no wallet, payment or NFT is required. Trial ends 2026-09-25 03:00 UTC. This is not a purchased NFT benefit, a forecast or a trade instruction. Send only public or synthetic inputs. No tool-registry registration or independent demand is claimed.

## Free transaction intent check

MCP connection: `https://field-404kin.cv5gyqnshz.chatgpt.site/api/intent-check/mcp` (Streamable HTTP, no authentication). One read-only tool: `check_token_intent`. [Connection and scope](/agents/TOOLS.md). Maximum JSON-RPC request: 8192 bytes. No wallet, chain execution, safety approval or NFT gate.

[FIELD Intent](https://field-404kin-tools.eric-lee92.workers.dev/intent/) compares supported static ERC20/ERC721/ERC1155 calls with independently supplied expectations. [API contract](https://field-404kin-tools.eric-lee92.workers.dev/intent/api-spec.json). POST https://field-404kin-tools.eric-lee92.workers.dev/api/intent-check, JSON, maximum 8192 bytes. Default Node.js fetch is verified. No wallet, NFT or payment is required. `consistent_with_expectations` is a limited parameter match, never a safety verdict or authorization. No chain reads, simulation, SeaDrop mint validation or signing. Experiment ends 2026-09-25T03:00:00Z. [Run a synthetic example](/agents/TOOLS.md).
