What the numbers mean.

A short operating note for reading marketplace data responsibly.

Are these complete sales records?

No. Resalens shows a small sample of publicly visible listings. Yahoo! completed auctions provide realized listing prices; Mercari results are displayed listing samples and may include items still being processed.

How current are the results?

Each comparison includes a capture time. Prices can change, listings can disappear, and marketplace coverage can be incomplete. Open the original listing before deciding.

Which currency is shown?

Marketplace results are shown in Japanese yen. Plan prices use fixed JPY prices for Japanese users and fixed USD prices elsewhere; they are not live-FX conversions.

When does the free allowance reset?

The free plan includes 2 searches per month. The server-side account counter resets monthly.
