About the product
CardZ Marketcap is a daily market-cap index for graded collectible cards. Each card's market cap is its PSA 10 reference price multiplied by its verified PSA 10 population, covering Pokémon and One Piece printings. Browse the Top 100 heatmap, per-card history and a free public JSON API — no key required. CardZ Marketcap and Cardz.Game are related sites under the CARDZ brand.

For product owners
Promote CardZ Marketcap
Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps CardZ Marketcap in front of people instead.
- Back in the X and Threads rotation: CardZ Marketcap gets posted again instead of once.
- A promoted slot on the AppRater homepage, carrying a Promoted badge.
- A direct link to CardZ Marketcap from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
- A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
- Stays on the first screen however old the listing is, while new submissions push everything else down.
