GapSense vs 130point: When You Need Sold Prices vs When You Need Tradeable Gaps

Every Pokemon flipper who has ever tried to price a card on eBay has used 130point. It is the cleanest interface in the hobby for one specific question: what did this card actually sell for on eBay in the last few months? That is a complete tool for a complete question. GapSense answers a different question: what is the price gap for this card across nine different marketplaces, and is it worth flipping? If you only sell on eBay, you need 130point. The moment you consider any second venue, you also need GapSense.

Coverage comparison

Feature	130point	GapSense
Marketplaces	eBay (sold + active)	9 marketplaces: eBay, TCGPlayer, CardMarket, Courtyard, Phygital, CollectorCrypt, Renaiss, SNKRDUNK, Beezie
Web3 / NFT venues	None	4 (Courtyard, Phygital, CollectorCrypt, Renaiss) + Beezie vault
JP-only platforms	None	SNKRDUNK
Sold-price history depth	Long (years on eBay)	Rolling window per platform, with sample-size weighting
Cross-platform gap primitive	Not provided	buy_from / sell_to / gap_usd / gap_pct / confidence
Grade enforcement	User-filtered	Hard wall — PSA 10 ≠ PSA 9 ≠ CGC 10
Variant resolution	User-filtered	Enforced — alt-art, full-art, promo, language match
Execution metadata	Listing URL only	execution_mode, redemption_required, kyc_required, estimated_exit_delay_hours
Pack EV	None	Adjusted EV across 9 platforms
Agent / API access	Web UI only	Documented agent guide with USDC settlement

What each one actually returns

130point — eBay sold history for one card

You search a card name, set, condition. 130point returns the sold listings: price, date, condition badge, listing URL. It is a clean, fast read of one venue's tape. For verifying that your intended eBay listing is priced correctly, this is the right tool. It does the job of reading recent sold history without fighting eBay's own search UI.

GapSense — cross-platform gap for the same card

{
  "card_key": "obf::223::normal::psa-9::en",
  "primary_match": [{
    "buy_from":  { "platform": "tcgplayer", "price_usd": 142.50, "execution_mode": "direct" },
    "sell_to":   { "platform": "snkrdunk",  "price_usd": 187.25, "redemption_required": false },
    "gap_usd":   44.75,
    "gap_pct":   31.4,
    "confidence": "HIGH",
    "match_tier": "primary_exact",
    "tape_weight_buy":  0.91,
    "tape_weight_sell": 0.84
  }]
}

This is not a price lookup — it is a trade. GapSense commits to four claims before publishing: same card, same grade, same variant, gap survives platform fees. The methodology is documented at /methodology/cross-platform-gap.

Where they actually combine

The realistic Pokemon flipper workflow uses both:

1. GapSense scan ($0.29 USDC) → ranked list of cross-platform gaps for the week.
2. Pick one with confidence=HIGH and match_tier=primary_exact.
3. 130point check on the eBay sell side → confirm the eBay tape is real and recent.
4. Execute: buy on the cheap platform, list on eBay at the GapSense-suggested level, verified by 130point comps.

The two tools are answering different questions in the same workflow. 130point is your second-look on the eBay leg. GapSense is your first-look on the cross-platform spread.

When 130point is the only right answer

• Single-card eBay listing prep. You are about to list one card on eBay and want to confirm last-sold comps. Open 130point, type the name, done.
• Buyer research before bidding. Auction ends in 6 hours, you want to know what the same card has sold for in the last 90 days.
• Long historical depth. 130point's eBay history goes back years — useful for trend analysis on a single card.

When GapSense is the only right answer

• Cross-platform arbitrage discovery. Which cards are cheap on TCGPlayer or CardMarket and expensive on SNKRDUNK or Beezie right now? 130point cannot answer this — it only sees eBay.
• Web3 oripa flipping. Phygital, CollectorCrypt, Renaiss, Beezie. None of them surface in 130point.
• Algorithmic / agent buying. An autonomous trader needs a documented API with grade purity, variant resolution, and execution metadata — that is the GapSense agent guide.
• Pack EV decisions. 130point does not compute pack EV. GapSense publishes Adjusted EV at /pack-ev.

The honest summary

130point is the best eBay sold-price reader in the hobby. Nothing in this post takes that away. The mistake is treating eBay's tape as the whole market — there are eight other venues GapSense tracks, and the largest cross-platform spreads usually involve at least one of them, not eBay-internal differences. Use 130point for the eBay leg of any trade. Use GapSense to find which trades are worth doing in the first place.

If you are pricing one card to list on eBay tomorrow: open 130point. If you are looking for which cards are mispriced across the whole market this week: GapSense momentum or opportunities preview first, then 130point on the eBay leg.
