Cambridge TCG Commons
We map free/open resources, publish safe Cambridge TCG public signals, and make it easier for collectors, players, sellers, stores, builders, and researchers to cooperate without hiding the basics behind walls.
01
Free first: publish the map, examples, and context before asking anyone to pay.
02
No private data: share aggregate/public signals, not customer identities or order details.
03
Attribution and terms: respect upstream APIs, licenses, rate limits, and brand rules.
04
Cache and mirror responsibly: use free compute for public snapshots, not for scraping abuse.
05
Make it useful to every party: collectors, players, sellers, stores, builders, and researchers.
The commons is useful only if every side can see themselves in it. These needs guide what we publish first and what we keep private.

Data, compute, code, public spaces, and contribution paths. Use them to build helpful community tools — with attribution, caching, and respect.
public
Free Cambridge TCG price pages for UK-facing Japanese TCG retail and trade-in context.
Care note: Operational prices can move; always verify live item pages before checkout or trade-in.
public
Public liquidity, watch, trade, spread, and movement buckets generated from Cambridge marketplace data.
Care note: Use aggregate signals responsibly; do not infer or expose private customer behaviour.
free
Card metadata and images for Pokémon tooling, search, and collection prototypes.
Care note: Respect its API rules, attribution expectations, and rate limits; Cambridge pricing remains separate.
free
Best-in-class public card search/API design reference and free bulk data pattern for TCG builders.
Care note: Magic data is not Cambridge inventory; use as inspiration and respect Scryfall terms and rate guidance.
free
Yu-Gi-Oh! card metadata API for community tools and cross-game schema inspiration.
Care note: Follow API etiquette; do not mix third-party data into Cambridge commercial listings without review.
free-tier
CI, scheduled checks, static builds, data snapshots, and contributor validation for open-source commons.
Care note: Keep secrets out of public logs; use least-privilege tokens and do not run untrusted workflows with secrets.
free-tier
Edge-host static pages, lightweight public APIs, cache layers, and small scheduled jobs close to users.
Care note: Design for cache-first public data; avoid storing private customer data in public worker examples.
free-tier
Fast preview deploys for Next.js community pages and non-critical prototypes.
Care note: Production commerce deployments should use the account/plan that matches business usage and compliance needs.
open-source
Turn unused laptop/server time into reproducible local analysis of public CSV/JSON snapshots.
Care note: Separate public snapshots from private operational/customer data.
public
A crawler/agent-readable map of public Cambridge TCG pages and non-private capabilities.
Care note: Robots and API boundaries still apply; agents should avoid account, admin, and checkout flows.
open-source
A public backlog shape for data corrections, guides, API examples, and commons improvements.
Care note: Moderate contributions; never accept private data, credential dumps, or copyrighted scans without permission.
Data Commons
Collect once, publish many ways: Markdown for humans, JSON/JSONL for agents, and YUTABASE JSONL for CARD/THREAD imports. Every record carries source IDs, terms notes, confidence, source health, and a provenance "how" field.
Correct data: send card names, set mappings, links, and source notes — never private customer data.
Add tools: propose small, cache-first scripts that create public CSV/JSON snapshots or explain pricing safely.
Teach: contribute beginner guides, deck ideas, and market explainers that make the hobby easier to enter.
This is a public resource map, not a promise that every upstream source is suitable for commercial reuse. Check each source's terms, rate limits, and attribution rules.
