Built for resale tools and repeatable research

Plot median sold price by month or quarter to show buyers and sellers where a product is heading.

FAQ
eBay API questions
Is there an API for eBay price history?+
eBay's own sold data APIs stop at about 90 days, and Marketplace Insights is closed to new developers. CompSniper's GET /v1/research/sold returns up to 3 years of eBay sold history by keyword, on all 8 eBay sites, with one API key and no eBay developer account.
Is the 3-year history included on the free plan?+
Yes. Every plan, including the free plan with 100 requests a month, can query the full 3 years. Each page of up to 50 rows is one request.
How is this different from the standard sold search?+
GET /v1/scrape returns the most recent individual sales (about 90 days) with full listing fields, condition and optional AI cleanup, up to 240 per request. GET /v1/research/sold goes back up to 3 years with listing-level rows: sold price, units sold, average price, shipping and last sold date, reported in US dollars.
Why are some rows averages?+
Rows are listings, not single transactions. A multi-quantity listing that sold several units comes back as one row with soldUnits, averageSoldPrice and totalSales. Add singleUnitOnly=true when you want one-off sales only, for example graded cards or used electronics.
What does 3 years of history show that 90 days cannot?+
Trends. In our dated Nintendo Switch OLED example, a used console sold for about $250 to $265 through 2024, fell to $162 by mid-2025 and held around $170 to $190 in 2026. A 90-day window shows only the last quarter.
How do I get the most results?+
Keep the keyword short: brand plus model or set number. Every word must appear in the listing title, so long keywords match little. Page past 50 rows with page and read hasNextPage.
