AmiiboDex is getting a pricing layer built for collectors who want quick context before buying, selling, or checking whether a listing is reasonable. The first version adds a price column with direct eBay listing links for every figure, plus optional loose and new-in-box estimates when the pricing refresh job has enough marketplace data.

What the price column shows

Each AmiiboDex row can show two collector-friendly numbers: a loose estimate and a NIB estimate. Loose is for opened or out-of-box figures. NIB is for sealed, new, or new-in-box listings. When an estimate is not available yet, the row still links to live eBay search results so you can inspect current listings yourself.

Why the numbers are marked as estimates

Marketplace prices move constantly, and listing titles can be messy. A seller might bundle multiple figures, include NFC cards, sell an empty box, or use a character name in a misleading way. Goozamiibo filters obvious noise, splits loose and new listings, removes extreme outliers, and uses a median price, but it still labels the result as an estimate instead of a guaranteed value.

Where the data comes from

The automated refresh is designed around the eBay Browse API search endpoint, which returns active listing summaries including price, condition, title, item URL, and marketplace fields. The public AmiiboDex page also includes direct eBay search links, so collectors can review listings even when API estimates are unavailable.

How confidence works

  • High confidence: eight or more clean matches after filtering.
  • Medium confidence: four to seven clean matches.
  • Low confidence: one to three clean matches.
  • Unavailable: no clean matches, or no pricing refresh has run yet.

Why snapshots matter

A single price is useful, but history is better. Goozamiibo stores daily snapshots for up to six months, then prunes older records. That keeps Firebase usage modest while giving future charts enough history to show whether a figure is stable, climbing, or cooling off.

How collectors should use it

Treat the price column as a starting point, not a final appraisal. Check the listing photos, region, packaging condition, shipping cost, seller reputation, and whether the figure is actually official. The best buying decisions still come from comparing current listings with condition and source context.

The goal is simple: make AmiiboDex more useful at a glance without pretending marketplace estimates are perfect.
