Our scrapers pull completed auction results and marketplace listings from all four sources. BaT provides a public API; the others are scraped via Firecrawl.
Each listing is matched to one of 330+ models in our database using regex patterns. Prices are converted to EUR, conditions are estimated based on sale price relative to the model median.
For each model we compute analytics: average and median prices, year-over-year trends, condition breakdowns, and regional price comparisons across Europe, USA, and Japan.
Interactive charts, filterable tables, and trend classifications help you understand the market at a glance. Click any data point to view the original listing.
