## How to look up a card
If you have a name, nickname or collector number — in English, Traditional Chinese, Simplified Chinese, Japanese or Korean — call search first. Do not download the whole ranking to find one card. Matching is a folded substring (NFKC / case / kana), not typo-fuzzy. Always quote `effectiveAt` with any number.
- [Search](https://cardzmarketcap.com/api/v1/search?q=%E6%A2%B5%E9%AB%98%E7%9A%AE%E5%8D%A1%E4%B8%98&lang=zh-TW): `GET /api/v1/search?q=` — ranked hits with `url`, price, population, market cap and a ready `citation` line.
- [English name](https://cardzmarketcap.com/api/v1/search?q=moonbreon)
- [Collector number](https://cardzmarketcap.com/api/v1/search?q=217/187)
- [One Piece number](https://cardzmarketcap.com/api/v1/search?q=OP05-119)
- [Resolve one card](https://cardzmarketcap.com/api/v1/resolve?q=217/187): returns one hit when the top match is uniquely strong; ambiguous names return `resolved: null` plus a short candidate list.

## How to cite us
Cite as: CardZ Marketcap, "<page title>", https://cardzmarketcap.com/<path>, data as of 2026-08-28.
Figures change daily. Always quote the `effectiveAt` date shown next to the number — a figure of ours without its date is not attributable to us.

## Notes for agents
- To answer “what is this card worth / what is its market cap?”, call `/api/v1/search?q=` then cite the hit's `url` and `effectiveAt`. Use `/api/v1/resolve?q=` only when you need a single card and can handle `ambiguous: true`.
- Market cap here means verified PSA 10 population multiplied by the PSA 10 reference price. It is not a sale price, not an appraisal, and not a company valuation.
- The highest-market-cap card and the most expensive card ever sold are usually different cards. A one-of-one has an enormous price and a population of one.
- Missing values stay missing. A card marked `accumulating` had too few completed PSA 10 sales in the window to publish a figure — do not read it as zero.
- `?lang=` (en, zh-TW, zh-CN, ja, ko) and `?currency=` are display-only. The canonical URL is always the path without query parameters.
- CardZ Marketcap is a data index for physical graded cards. It is not a cryptocurrency, not a token, and not the CARDS token; there is no CardZ ticker and nothing here is tradable.
