SoldComps EverDevSoldComps's answer
SoldComps returns real eBay sold listings โ completed sales, not active listings or estimates โ from a single API call.
One keyword search returns up to 240 sold items, each as clean JSON with:
Most tools lock this data behind a dashboard or require an approved eBay developer account. SoldComps hands it back as a simple authenticated GET request you can integrate in minutes โ across 8 eBay marketplaces.
SoldComps's answer
It's built API-first for people who want the data, not another dashboard to log into.
No eBay developer account, OAuth flow, or approval process โ just an API key and a GET request that returns clean JSON. What you get:
Pricing is per search, not per result โ a search that returns 10 items or 240 counts as one request โ and there's a free tier with no credit card to start.
SoldComps's answer
SoldComps serves four main audiences:
SoldComps's answer
SoldComps started from a simple, recurring frustration: eBay is the best source of real sold-price data, but actually getting that data is painful.
eBay's own API heavily restricts access to sold listings and gates it behind an approval process, and pulling comps by hand is slow and doesn't scale.
So SoldComps collapses all of that into one clean API call โ pass a keyword, get back up to 240 completed sales as structured JSON โ so resellers and developers get the pricing data they need without wrestling eBay's API or scraping it themselves.
SoldComps's answer
SoldComps is built in TypeScript โ a Hono API backed by PostgreSQL, with a React web app. Billing runs on Stripe.
SoldComps's answer
SoldComps is used across its core audiences rather than a few big-name accounts:
