How PriceSnap works
PriceSnap estimates what an item may be worth from a photo or a short description. It validates the comparable listings it finds, derives the range from the evidence that survives, and withholds numeric pricing when coverage is too thin. This page explains what is checked, what the confidence labels mean, and what PriceSnap still cannot verify.

What a valuation includes
A PriceSnap result identifies the item (brand, model, and the visible signals behind that call), then searches for comparable listings in your confirmed pricing area. When at least two mutually consistent usable listings remain, their lowest, median, and highest prices become the range and the Quick Sale, Market Price, and High Ask guides. Results also show the retained sources, exclusions, identity confidence, market-evidence confidence, and, for products still sold in stores, current retail offers.
The evidence types, and how each is labeled
Not every price means the same thing. A reported-sold listing, an asking price, and a retail offer are different kinds of evidence, and PriceSnap keeps them visibly separate on every result.
Reported sold listings (unverified)
Search results that appear to describe a sold or completed listing. Unless a marketplace data provider verifies the transaction, PriceSnap labels these as reported sold rather than proof that money changed hands.
Useful market evidence, but currently capped below High confidence because the sale status is not independently verified.
Active listings (current supply)
Items currently for sale. An active listing shows what sellers hope to get right now — it is supply, not a realized sale.
Context for demand and asking-price spread. Never counted as money that changed hands.
Asking prices (unverified)
A seller's requested price where the sale status is unclear. Asking prices can sit far above what buyers ultimately pay.
Weakest evidence. Used for orientation only and never presented as a realized sale.
Retail offers (buy-it-new prices)
Current offers from retailers for new or refurbished stock, each with the date it was observed. Retail offers are not comps and never feed the resale estimate.
Shown separately in the "Where to buy" module, cheapest first. Prices can change at checkout.
How an estimate is produced
- 1
Identify
From your photo or typed details, PriceSnap identifies the item and the signals that matter for value: brand, model, variant, and visible condition cues like labels, boxes, or wear.
- 2
Search the market
A market-aware search checks marketplaces and retailers for comparable items in your confirmed pricing area. Search-result labels are treated as unverified unless a marketplace provider proves the transaction.
- 3
Validate and calculate
Unsafe URLs, missing or non-positive prices, mixed currencies, duplicates, stale dated listings, and defensible minority outliers are removed. If two prices disagree by 5× or an evenly split market cannot be resolved, pricing is withheld. Otherwise the range and seller guides are calculated from retained inliers, not copied from a generated estimate.
Confidence levels
Results separate confidence in the item identity from confidence in the market evidence. The overall confidence is the lower of the two, so a clear product photo cannot make weak pricing evidence look strong.
High
Reserved for evidence that can be verified as sold, is dated, and spans at least three independent sources. Current web-search listing evidence does not qualify.
Medium
At least three usable inlier listings across two sources support a range, but listing status may still be based on search-result interpretation.
Low
Only a directional range is available, or the item identity is uncertain. With fewer than two usable comps, the numeric valuation is withheld entirely.
What lowers confidence
- Fewer than three usable listings or evidence from only one source.
- Reported-sold status that cannot be verified through a marketplace feed.
- No visible brand labels, model numbers, or other identifying details in the photo.
- Condition that cannot be judged from the photo.
- Thin, volatile, or mostly private markets for the item.
What PriceSnap can't price well
Honest coverage matters more than confident-sounding numbers. These are the cases where you should treat any estimate — ours included — with extra caution.
One-of-a-kind items
Unique art, one-off antiques, and handmade pieces often have no comparable sales. When fewer than two usable listings remain, PriceSnap withholds the numeric range instead of manufacturing a precise number.
Items with thin or private markets
Very new releases, niche equipment, and items that mostly sell through private deals leave little public evidence to search.
Condition-critical collectibles
For graded cards, comics, coins, and watches, small condition differences move value a lot. A photo cannot replace an in-person or professional grade, so treat the range as a starting point.
Anything requiring physical inspection
Authenticity checks, internal damage, repairs, and missing parts are invisible to a photo scan and can change value materially.
“Where to buy” offers are not sold comps
For products still sold in stores, results can include a “Where to buy” module: current retail offers from distinct retailers, each labeled Retail offer with the date it was observed, sorted cheapest first. These offers answer “where can I buy this new, and for how much” — they are not evidence of what the item resells for, and they are never mixed into the comps behind the value range. Retail prices can change at checkout, so verify on the retailer's site before buying.
Our evidence-honesty rules
- An active, asking, or merely reported-sold price is never presented as a verified transaction.
- The lowest, median, and highest retained inlier prices determine the displayed range and seller guides.
- Different subdomains of one registrable marketplace count as one source, and unresolved 5× price conflicts produce no range.
- “Insufficient market evidence” replaces the range, profit calculator, and price watch when fewer than two usable listings remain.
- Retail offers are always labeled as retail offers, with the date they were observed.
