Collectible cards, trading card games (TCG) and collectibles.

This release brings CardZ Marketcap's public Pokémon and One Piece data into your AI conversation. Search an exact printing, inspect its PSA 10 reference price and daily history, or explore the published market rankings.

Features

  • Card search: find candidate printings by name or collector number, with language and set details.
  • Card details: view a dated PSA 10 reference price, population, market capitalization and daily history.
  • Market rankings: explore Pokémon, One Piece or the combined tracked index in its published order.

In hosts that support MCP Apps, the same three tools provide an interactive view with card artwork, printing selection and history controls. Other hosts receive the structured data and card-page links.

Current data coverage is Pokémon and One Piece PSA 10 cards. Prices are daily reference observations in USD, rather than live executable quotes. Market capitalization is the reference price multiplied by the printing's PSA 10 population. Missing values remain unavailable.

Privacy

Public lookup requires no CARDZ.Game account. The tools do not request player passwords, addresses, payment details or wallet information.

Search terms and necessary lookup parameters are sent to the CardZ Marketcap public API. Cloudflare handles transport, execution and connection information needed for security. The service uses source IP addresses for rate limits and does not create player profiles. It has no custom query-history database, and Worker application logs are disabled in this release's configuration.

Successful public API responses may be cached at the Cloudflare edge for 60 seconds. The interactive view loads only public card artwork through a restricted CARDZ image route; images may be cached for 24 hours. It includes no analytics or browser storage.

Your AI platform's privacy policy governs its handling of conversations and tool results. Cloudflare's cross-border processing follows its Data Processing Addendum and applicable Standard Contractual Clauses. Government or third-party data requests receive legal review before disclosure.

Use

This release provides public data lookup. It has no account, purchase, pack-opening, auction, shipping or payment tools. Cite the card page and the original data dates. Requests are rate limited; retry later after an HTTP 429 response. Data dates may differ from the time of your query.
