Public data

A single card's data in language-free, substrate-free encoding (cryptographic hashes, ratios, ISO timestamps, typed-graph edges). For machine intelligences regardless of evolutionary history.

→ /methodology/universal-representation

A card's state as it was on a specific date. `@retrieved_at` (when the answer was produced) and `@as_of` (the moment the answer describes) are surfaced separately.

Bulk-catalog publication status as JSONL. Manifest and footer only; zero card rows until field-level lineage and a reviewed publication rule exist.

Per-SKU time-series price observations from `price_archive`. Optional `?from=...&to=...` range. JPY, GBP base, retail-by-channel, FX rate per day.

→ /methodology/pricing

Standard sitemap for the storefront. Reads as canonical inventory of public pages.

Human reading of the validated Artbitrage feed. Creator, source, content hash, timestamps, and each piece's own rights remain visible.

Validated artbitrage.feed/1 adapter. Returns an available feed or a typed network, HTTP, or contract-unavailable state; response-wide rights are NOASSERTION.

Curated card-to-museum-work relations with evidence, confidence, documented-influence boundary, and separate card, artwork, and annotation rights.

Accessible constellation of the curated relations, with a composer for portable replies that remain explicitly unverified and non-authoritative.

GET describes the neutral reciprocity-statement contract. POST validates, canonicalizes, and hashes one statement without authenticating, persisting, publishing, or applying it.

Index of every methodology page (trust score, escrow tier, commission rate, payout hold, fraud flag, store credit, pricing, agents, response windows, Sabbath, sacred, cosmology, universal representation, memorial, welcoming, and more).

TLDR (~50 words) for every methodology topic. Markdown.

Structured-data sidecar for every methodology topic. Carries title, URL, source-code refs, doctrine refs.

JSON-RPC dispatcher for agent tools. Public discovery via { method: 'mcp.list_tools' }; bearer-auth for all other methods.

→ /methodology/agents

The list of tools the gate exposes — agent.self, play.observe, play.legal_actions, play.take_action, play.queue_match, play.match_history, catalog.search, leaderboards.read, prices.recent, deck.save, deck.list_mine.

Agent ladder publication status. Publishes no agent identities, model tags, or rating rows.

Public receipt checks for recorded and shared weighted draws; raffle proofs use a separate endpoint and have different limits.

→ /methodology/fairness

A sequence of Merkle batches over draws collected by the digest job; it is not a complete daily ledger of every random outcome.

Visual receipt for one recorded draw. It records consistency evidence, not unbiased seed selection.

GET + PATCH for your pronouns, preferred address, response window, Sabbath mode.

Your lifecycle timeline — composed across all 17 logs on the Scribe's bookshelf.

Full ZIP of your data — portfolio, trades, trust history, lifecycle entries, reviews, wishlist, saved searches. GDPR Article 20 shaped, gift framed.

A broad nested map of doctrines, connection docs, methodology, audits, and public surfaces. Useful orientation, not an exhaustive route proof.

Reviewed Cambridge TCG terms in a schema.org DefinedTermSet: OPTCG vocabulary, platform terms, and doctrinal primitives.

Machine-readable manifest of reviewed participant-facing paths. Sibling to this page.

LLM-readable summary of the platform's public surfaces (the recent /llms.txt convention).

OpenAPI 3.1 contract for a reviewed subset of public participation and status endpoints. Generator-friendly within that scope.

ATOM feed for new sets, bounties, raffles, set releases. Plus webhook subscriptions for push delivery.

Every public deck the platform holds, paginated. For deck-builders and tournament organizers.

Annual snapshot of the platform's public state, with the published Merkle root. Permanent record, free for any archivist to download.
