## What is Contendr?

Contendr is the marketplace for raw, ungraded trading cards — where every listing is AI-graded before it goes live.

Raw cards are hard to buy online. "Near mint" means whatever the seller wants it to mean, and the photos never show the corner that's soft. Contendr fixes that: you cannot list a card here without grading it first.

AI GRADING, BUILT IN
Photograph the front and back and Contendr measures the card the way professional graders describe it: centering from real border widths, corners, edges and surface — reported to two decimals with a confidence score. Every grade comes with a Defect Map: zoomed photographic evidence of each worn corner and edge, pinned to the exact spot on your card.

A CATALOG THAT KNOWS YOUR CARD
Over 190,000 cards — Pokémon (English and Japanese), Magic: The Gathering, Yu-Gi-Oh!, One Piece, and sports. Scan a card and Contendr reads it, or search by name, set or number. Card pages show current market values across grades, from ungraded through PSA 10, plus live eBay listings for comparison.

BUY WITH PROTECTION
Bid in eBay-style auctions or buy instantly. Your payment is held in escrow while the card ships — the seller is paid 48 hours after delivery, giving you time to check the card against its grade report and photos. Not as described? Open a claim in that window.

SELL IN MINUTES
Grade, list, and when it sells, print a prepaid shipping label right in the app and drop it in the mail. Cards ship straight to your buyer. Running low on supplies? Order sleeves, toploaders and mailers from the app.

FEES
Grading a card to list it is free — the 8% final value fee on sales covers it (includes escrow and buyer protection). No fee to browse or watch.

Grading a card you keep, without listing it, uses one credit. Every account starts with 3 free credits. Credit packs: 5 for $2.99, 25 for $9.99. Contendr Pro gives unlimited kept grades for $19.99/month.

IMPORTANT
Contendr's AI grade is a machine-generated estimate. It is not a professional grade and may not match PSA, BGS, SGC or any other grading company. Contendr sells raw (ungraded) cards only.

Contendr Pro is an auto-renewing monthly subscription at $19.99/month. Payment is charged to your Apple Account at confirmation and renews unless cancelled at least 24 hours before the period ends.
