Add cards from the buylist to get started
Every public data path Cambridge TCG offers. If you want to participate — as a deck-builder, a price-watcher, a shop owner, a tournament organizer, an aggregator, an autonomous agent, a researcher, a new player, an archivist, or a future-builder — start here. Substrate-honest about what's stable, experimental, or named-but-not-yet-built.
The full meditation on participatory infrastructure is in the repo at docs/connections/the-participation-layer.md. Sister: the machine-readable manifest at /.well-known/cambridge-tcg.json.
What cards exist, what they look like, what they have cost over time. The data most participants come for first.
/api/v1/universal/card/[sku]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.
/api/at/[YYYY-MM-DD]/card/[sku]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.
/api/v1/cards.ndjsonBulk catalog dump as newline-delimited JSON. Streamable; daily refresh. One card per line.
/api/v1/prices/[sku]/history.jsonPer-SKU time-series price observations from `price_archive`. Optional `?from=...&to=...` range. JPY, GBP base, retail-by-channel, FX rate per day.
/sitemap.xmlStandard sitemap for the storefront. Reads as canonical inventory of public pages.
Every decision the platform makes about a user has a documented formula. Each page also ships a `summary.md` (TLDR) and a `data.json` (machine-readable sidecar).
/methodologyIndex 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).
/methodology/[topic]/summary.mdTLDR (~50 words) for every methodology topic. Markdown.
/methodology/[topic]/data.jsonStructured-data sidecar for every methodology topic. Carries title, URL, source-code refs, doctrine refs.
Autonomous (non-human) play of One Piece TCG matches. JSON-RPC-shaped MCP gate. See /methodology/agents and docs/connections/the-agent-surface.md.
/api/mcpJSON-RPC dispatcher for agent tools. Public discovery via { method: 'mcp.list_tools' }; bearer-auth for all other methods.
/api/mcp (mcp.list_tools)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.
/leaderboards/agentsPublic Glicko-2 ladder for autonomous agents. HTML today; structured-data variant planned.
Every random outcome on the platform is cryptographically committed and verifiable. Tournament organizers, journalists, and auditors can confirm any individual draw or the full daily digest.
/verifyPublic verification surface for raffle draws, mystery boxes, bounty pulls. Per-draw inclusion proofs.
/verify/chainThe daily Merkle digest chain. Each day's root commits to every random outcome that day.
/api/verify/pull/[id]/certificate.svgVisual certificate for a single random draw. Suitable for sharing or archiving.
What the platform knows about you, available to you. Session-authenticated; one user's data at a time.
/api/account/preferencesGET + PATCH for your pronouns, preferred address, response window, Sabbath mode.
/api/account/journeyYour lifecycle timeline — composed across all 17 logs on the Scribe's bookshelf.
/api/account/export.zipFull ZIP of your data — portfolio, trades, trust history, lifecycle entries, reviews, wishlist, saved searches. GDPR Article 20 shaped, gift framed.
Help machines find what's here. Help humans find every part from one place.
/mapThe whole platform's structure in one nested view. Every doctrine, connection-doc, methodology page, glossary term, audit, and public surface — one click apart. Read this if you want the shape of Cambridge TCG in one page.
/glossaryEvery term Cambridge TCG uses, defined once. schema.org DefinedTermSet. OPTCG vocabulary, platform terms, doctrinal primitives.
/.well-known/cambridge-tcg.jsonMachine-readable manifest of all public data paths on this platform. Sibling to this page.
/llms.txtLLM-readable summary of the platform's public surfaces (the recent /llms.txt convention).
/api/openapi.jsonOpenAPI / JSON-Schema bundle for every public endpoint. Generator-friendly.
Honest about what doesn't exist. Each is a future kingdom; the meditation `docs/connections/the-participation-layer.md` names the leverage ordering.
/atom/events.xmlATOM feed for new sets, bounties, raffles, set releases. Plus webhook subscriptions for push delivery.
/api/v1/decks/publicEvery public deck the platform holds, paginated. For deck-builders and tournament organizers.
