SoldComps eBay sales API: $19K MRR, up to 200 results

SoldComps provides an API for completed eBay sales data used in pricing research and integrations. Its $19K MRR is verified through the payment provider's API by TrustMRR (Stripe), as of September 30, 2026.

What it actually sells

One GET request returns up to 200 completed eBay sales. Responses include sold prices, shipping costs, currencies, sold dates, item conditions, seller feedback, and direct links to listings.

Results can be filtered by category, price, condition, and date. All plans include access to 8 eBay marketplaces and up to 90 days of history per search.

How it charges

Every plan, including the free plan, permits commercial use. The free plan provides 100 monthly requests, representing up to 20,000 sold listings. The product's price could not be identified on the pages we read, although currency amounts appear on them.

Where it sits in the data

SoldComps's $19K MRR is higher than 96% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Real Estate” category (108 projects) it is higher than 98% (category median $156). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that this needs real work. Demand comes from businesses and developers that need completed-sales data for pricing research, integrations, and client deliverables. Distribution would have to come from developer communities, reseller communities, content explaining the API, and free evaluation access.

The difficult parts are maintaining reliable data retrieval, keeping integrations stable, documenting the product clearly, and supporting customers who depend on it inside their own systems. Platform terms, data rights, and marketplace access also require careful review.

Verdict: Needs real work.

One thing to take from it

The useful lesson is to sell a specific data workflow through a product developers can test, inspect, and integrate. A live demo, free account, documentation, and JSON examples give buyers a direct way to evaluate the API.
