Questions & Answers

As answered by people managing SoldComps and SelectStar.

What makes your product unique?

SoldComps's answer

SoldComps returns real eBay sold listings — completed sales, not active listings or estimates — from a single API call.

One keyword search returns up to 240 sold items, each as clean JSON with:

  • Sold price, shipping, and currency
  • Condition and sale date
  • Seller info and a direct item URL

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 — across 8 eBay marketplaces.

Why should a person choose your product over its competitors?

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 — just an API key and a GET request that returns clean JSON. What you get:

  • Up to 240 completed sales per search, across 8 eBay marketplaces (US, UK, DE, FR, IT, ES, CA, AU)
  • Fetched live, so results are never stale
  • Filters for category, price, condition, and date window

Pricing is per search, not per result — a search that returns 10 items or 240 counts as one request — and there's a free tier with no credit card to start.

How would you describe the primary audience of your product?

SoldComps's answer

SoldComps serves four main audiences:

  • Resellers & flippers — price inventory from real sold comps before buying at thrift stores, estate sales, and storage auctions
  • Developers — build price-comparison tools, repricers, or valuation features on clean eBay sold data instead of scraping it themselves
  • Market researchers — analyze demand, price ranges, and sell-through from completed sales
  • Estate-sale & liquidation operators — price large lots quickly

What's the story behind your product?

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 — pass a keyword, get back up to 240 completed sales as structured JSON — so resellers and developers get the pricing data they need without wrestling eBay's API or scraping it themselves.

Which are the primary technologies used for building your product?

SoldComps's answer

SoldComps is built in TypeScript — a Hono API backed by PostgreSQL, with a React web app. Billing runs on Stripe.

Who are some of the biggest customers of your product?

SoldComps's answer

SoldComps is used across its core audiences rather than a few big-name accounts:

  • Resellers and flippers pricing inventory before they buy
  • Developers adding eBay sold-price data to their apps
  • Market researchers analyzing demand and pricing trends
  • Estate-sale and liquidation pros pricing large lots fast
