Cross-posting network

List once.
Sell everywhere.
Never undersell.

Your inventory should be working on every marketplace at once. 2 channels live today, plus 9 more in official-API partnership — all included with Pro Seller Ultimate.

We only list channels we can publish to through an official API. Anything not marked Live is not billable today — you are paying for the channels that are live plus locked-in access to the rest. As each partnership goes live, every Pro Seller Ultimate member gets it at no extra cost — your rate is locked to the stage you joined on.

How cross-posting works.

One scan, every storefront: Scan a card into your vault and publish it to every connected marketplace in one tap — or in bulk, up to 1,000 cards at a time.
Fees and net proceeds up front: See the estimated marketplace fee, Rookie seller fee, and what actually lands in your pocket on each channel before you list.
Never oversell: When a card sells anywhere, Rookie pulls the listing down everywhere else automatically — no double sales, no angry buyers, no manual cleanup.
Priced by evidence, not guesswork: Every listing is anchored to live sold comps, PriceCharting, COMC, and Rookie's own sale history — with a shareable comp report that justifies your ask.

Built for the whole hobby

One collector or ten thousand cards.

The same pricing intelligence, cross-posting, and protections whether you own three cards or three showcases.

Collectors

Know what you're holding.

Daily re-pricing on your whole vault, buy/sell/hold guidance with a fair-value range, and alerts when a card crosses your target.

Sellers & flippers

More eyeballs per card.

The same card working on Rookie, eBay, and every channel we light up next — with net-proceeds math per channel so you list where you make the most.

Card shops & dealers

Move inventory, not spreadsheets.

Bulk cross-list up to 1,000 cards at a time, auto-list new intake by rule, and let sold-sync retire listings across channels.

Breakers & consignors

Prove the price.

Shareable, comp-backed value reports for every card — ordered most-similar-first — so buyers see why a card is worth the ask.

Cross-posting lives in the app.

Connect your channels and publish from the Rookie app. Memberships are purchased in-app under Settings → Membership.
