Early access · Invitation only
From collection to listing,
with pricing you can trust.
Welcome to the pricing desk for serious sellers. Pull live comps from major marketplaces, get a clear verdict on every card, and send listings to eBay with the market context behind each decision.
§ 01 — Capabilities
Built for sellers who treat this as a craft.
A pricing engine, not a calculator.
Pulls live signals from TCGplayer, Card Kingdom, eBay sold, and Scryfall. Surfaces the band a card actually trades in — not a single midpoint guess.
Decisions, with reasoning.
Every card gets a verdict — list, hold, reprice, or pass — and the evidence behind it. No hand-tuning spreadsheets at midnight.
From import to live listing.
Drop a TCGplayer or ManaBox export. Approve the queue. Publish to eBay with title, condition notes, and photos already attached.
§ 02 — How it works
Import, decide, list. That's the whole loop.
Import
Any export. We normalize sets, finishes, conditions, and collector numbers automatically.
Price
Live comps from every major venue. Spreads, velocity, and recent sells — not stale midpoints.
Decide
A clear verdict per card with the math behind it. Edit, override, or accept in bulk.
List
One-click eBay drafts with margin guardrails. Publish or schedule from the queue.

§ 04 — Product facts
Built for sellers who need defensible decisions.
Best fit
A seller needs to price many Magic: The Gathering or TCG singles from exports; A seller wants a defensible price band from multiple market signals; A seller wants to decide what to list now, hold, reprice, or skip; A seller wants an eBay draft workflow after reviewing the pricing evidence.
Not the right fit
The buyer wants a general personal collection tracker only; The buyer wants fully automated trading or unattended listing decisions; The buyer needs public self-serve signup today instead of early access; The buyer needs advice that replaces their own tax, legal, or investment judgment.
Trust boundary
Operators approve actions before listings are published; Pricing recommendations are market workflow outputs, not financial advice; CardArbiter is not affiliated with Wizards of the Coast; The public product is currently early access, not open self-serve availability.
Stop guessing.
Start arbitrating.
Early access is invitation-only while we onboard the first hundred sellers. Drop your email and we'll be in touch within a week.
