Priceluma: Compare Prices

By Uladzimir

Overview

Priceluma helps shoppers and sellers compare typical asking prices for products using sampled marketplace price data. Analyze a product model in a chosen shopping country and currency, compare new and secondhand prices, and see sample sizes, medians, the middle price range, and price distributions. Results summarize retrieved offers, not the whole market or completed sales. Model matching relies on listing text; shipping, taxes, stock, and product identity may be unconfirmed. Priceluma explains limited coverage and missing statistics. It provides price analysis and does not place orders or process payments.

Analyze sampled asking prices by condition in one currency, defaulting to USD. Pass models for deterministic matching of model identifiers and accepted aliases in listing titles and variant options; omit only for broad category searches. Common accessory cues and explicit bundles are excluded when models is provided. All returned amounts use integer minor units of the requested currency. Foreign prices use latest available daily exchange rates. P25–P75 is the middle half of the sample, not a confidence interval. Each group contains inclusive price bins sized independently from that condition's observations. A sparse high-price tail may use a final bin with upperInclusive null, displayed as XXX+. bucketCount overrides the total per group, including overflow. Statistics include all offers; statistics and histograms require at least five observations per group. Product identity, shipping, taxes, and stock may be unconfirmed. Coverage describes collection completion, not market coverage. Read all returned messages.
