DealCatch
The engine watches. You act.
DealCatch is Dexcatch's price intelligence engine. It calculates the fair value of every card, pulls real-time eBay listing data, and tells you exactly what each offer is worth — before you click buy.
Not a market price. A calculated one.
TCGPlayer shows what sellers are asking. eBay shows what sold. Neither tells you what a card is structurally worth. Dexcatch runs a proprietary calculation across two core signal areas to arrive at a single defensible number — Fair Price.
The engine reads the live market on every card — TCGPlayer market price, 30-day eBay sold median, active listing supply, and platform spread between the two markets. These signals are weighted and blended into a baseline that reflects what the card is actually transacting for in the current market, not what someone hopes to get for it.
Every card carries a structural scarcity level determined by its pull rate, pool size, and how many cards compete for the same rarity slot in its set. A card requiring 900 packs to pull is fundamentally different from one requiring 150 — even if the market prices them similarly. Pull economics adjust the fair value baseline to reflect structural scarcity, not just surface price movement.
DealCatch pulls real-time listing data from the eBay API on every scan cycle. Before any listing reaches the engine, it passes through Dexcatch's proprietary data quality layer. Graded copies, non-English cards, auction-format listings, and statistical price outliers are automatically excluded. What remains is a clean pool of relevant, comparable, buyable listings. The engine only scores what it trusts.
Every listing gets one of four outcomes.
DealCatch compares the list price against the Dexcatch Fair Price for that specific card and assigns a single verdict. No ambiguity. No interpretation required. You know exactly what the offer is the moment it surfaces.
Significantly below what comparable sold data and structural scarcity support. Strong buy signal. These are rare and sell fast — DealCatch is built for exactly this moment.
Below market equilibrium. A real entry point — not a once-in-a-generation discount, but a genuine opportunity if you were planning to buy anyway.
Trading at what the data supports. No urgency either direction — but now you have a baseline to negotiate from instead of guessing.
The seller is anchoring above what comparable transactions support. You know the spread. Make a lower offer or move on — the data is on your side.
Set it once. Let it run.
You tell the engine which cards matter and what qualifies as a deal. It handles the scanning, scoring, and alerting on every cycle — automatically.
Search any card from the Dexcatch inDex catalog and add it to your Catches. You're watching that specific card — set, rarity, version — not a keyword.
Choose your alert trigger: Steal Only, Best or Better, or Any Deal. Pro users can also set a custom dollar threshold — alert me when this card drops below $X.
On every cycle, the engine pulls fresh eBay data, applies the quality layer, scores every active listing against Fair Price, and checks for qualifying offers on your cards.
When a qualifying listing fires, you're notified. The alert includes list price, Fair Price, spread, verdict, and a direct eBay link so you can buy before it sells.
The market in both directions.
Every scan, DealCatch surfaces the top 5 best deals and the top 5 most overpriced listings — free. The deals show you where to act. The overpriced list shows you what to avoid, and proves the engine calculates across the full price spectrum, not just the cheap end.
Watch the cards that matter to you.
The top 5 lists show you what the engine found today. Catches let you tell the engine exactly what you're hunting — and get alerted the moment it surfaces.
How Catches work
Add any card to your Catches and set your alert threshold. On the next scan cycle, the engine queues your card, scores qualifying active listings, and moves the Catch from Watching to Found if something hits your threshold.
The Found state includes the full deal analysis — list price, Fair Price, spread, verdict, deal signals, and a direct eBay link. From there, you click through and buy before the listing sells.
If the listing sells before you act, the Catch returns to Watching and resumes scanning on the next cycle. You never lose the slot — you just wait for the next qualifying offer on that card.
DealCatch maps every active listing back to your specific card — set, number, rarity tier — before it scores anything. A listing for “Pikachu ex” that doesn't match your exact version doesn't reach the engine. If no qualifying offer exists at the time of the scan, your Catch stays in Watching. That's not a failure — it means the market doesn't have a deal on that card right now.
Is the market working for you or against you?
Every DealCatch scan measures market pressure — whether conditions currently favor buyers or sellers. This context changes how you should act on any given verdict.
Supply outpaces demand. Sellers are competing for buyers, listings are sitting longer, and Best Offer acceptance rates are up. In a buyers market, a Best Deal may be negotiable and a Steal is more likely to hold. This is when DealCatch is most productive.
Demand outpaces supply. Listings are selling fast and prices are trending up. A Fair verdict may represent a genuine buy before prices climb further. A Steal in a sellers market is extremely rare — and it will sell before most people even see it.
