Frequently Asked Questions

FlipScore™ is FlipFoundry's deal-quality score. It evaluates each active listing using sold comps (verified eBay sales), Best Active Ask, estimated eBay fees, shipping, and condition/grade fit. The result is an estimated net ROI — the amount you'd pocket after a realistic resale. Higher FlipScores indicate stronger deals backed by more comp evidence.

Market Value is derived from recent verified eBay sold prices for the same card, grader, and grade. Guide Value is a reference price from SportsCardsPro — a third-party price guide. Guide values are estimates, not market prices. When available, FlipScore™ uses Market Value (sold comps) as the primary signal; Guide Value is shown as a secondary reference.

When you search a card, FlipFoundry queries eBay for active Buy-It-Now listings and recent sold comps. It clusters exact matches (same player/character, grader, grade) and runs the FlipScore™ algorithm — comparing the best active ask against the sold median, factoring in fees and shipping, and surfacing an estimated net ROI with a confidence rating.

No. All estimates are based on historical eBay sold data and are for research purposes only. Market conditions change, and actual sale prices vary. FlipFoundry helps you identify better-than-average buying opportunities, but past performance does not guarantee future results. Always do your own due diligence before buying.

Yes. FlipFoundry scans both sports cards (PSA, BGS, CGC, SGC) and Pokémon (PSA, BGS, CGC). Pokémon raw support is available in beta with condition and data-confidence safeguards — thin-data listings may show Research or No Data while graded slabs across both verticals are fully supported.

A cluster groups multiple eBay listings of the same graded card (same player/character, grader, and grade) into a single analytical unit. FlipFoundry compares active Buy-It-Now listings against recent sold prices to identify cards priced below fair market value. Each cluster shows the best deal, median sold price, edge %, and confidence score — so you can instantly see which cards are worth buying.

Underpricing is calculated by comparing the lowest active listing price against the median sold price from the last 30 days of verified eBay sales. For example, if the median sold price is $200 and the best active listing is $150, that card is 25% underpriced. We also factor in eBay fees, shipping, and payment processing to calculate your estimated net profit — so the numbers you see are what you'd actually pocket.

Liquidity tells you how fast a card is likely to sell once you buy it. High liquidity means 10+ sales in the last 30 days — these cards move fast and you can flip them quickly. Medium liquidity (5-9 sales) means reliable but slower turnover. Low liquidity (fewer than 5 sales) means the card sells infrequently — higher potential profit but longer hold times and more risk. We recommend starting with High liquidity deals.

Each signal is scored using exact comp matching against verified recent sales. The algorithm factors in edge % vs the 30-day sold median, comp count, and freshness weighting — so higher scores mean stronger, more recent evidence. High confidence means 10+ comps with tight price clustering. Medium means 5-9 comps. Low means fewer than 5 comps or high price variance.

eBay is the primary marketplace today, covering Sports Cards (PSA, BGS, CGC, SGC) and Pokemon (PSA, BGS, CGC). FlipFoundry uses the eBay Browse API for real-time active listing data and historical sold prices. Support for additional marketplaces is on the roadmap.

Listings are revalidated continuously — approximately every 60 seconds. Stale or changed listings are flagged and re-scored automatically. Dead signals (sold or delisted cards) are removed from your feed immediately, so you never act on outdated information.

The signal is automatically invalidated and removed from your feed. No manual cleanup required — dead signals disappear on their own. This is critical because acting on a sold listing wastes your time and money.
