eBay sold listings API · alternatives
Looking for an eBay sold listings API?
eBay's sold-data API is closed to new developers, and sold search on the site now needs a login. If you're pricing secondhand clothing, shoes or bags, SoldStack gives you real sold prices from Poshmark as JSON.
100 lookups a month free, no card. Paid plans from $9/month.
What happened to eBay sold data
- Marketplace Insights, eBay's API for sold items, is a limited release that isn't open to new developers.
- eBay's public APIs (like Browse) return active listings, which are asking prices, not what things sold for.
- Sold search on ebay.com now asks you to sign in, which breaks most scrapers.
To be clear: SoldStack doesn't have eBay data. If you need eBay specifically, look for a third-party provider that resells it. If what you're pricing is fashion, read on.
For clothing, shoes and bags: Poshmark
Most secondhand fashion in the US sells on Poshmark. SoldStack returns those sales cleaned of bundles, kids' sizes and mismatched items, with the median, range, days to sell, net after fees and a confidence rating.

Questions
Will you add eBay?
Only through a compliant source. eBay's sold API is closed to new developers today.
What about Mercari?
Mercari is next for fashion if developers ask for it. Email me if you need it.
Can I try it without code?
Yes: the price guide shows the same data, and Google Sheets works with a free key.
