CompSniper
Marketplace Insights API alternative · 2026

eBay sold data,
no partner approval.

Is there an alternative to the eBay Marketplace Insights API?

Yes. Marketplace Insights is eBay's only official sold-items API, but it is a Limited Release API for approved eBay partners, and the older Finding API call findCompletedItems was decommissioned in February 2025. CompSniper is the practical alternative: sign up, get an API key instantly, and one request returns up to 240 recent eBay sold listings as JSON across 8 marketplaces.

Side by side

CompSniper vs Marketplace Insights

Both return completed eBay sales. The difference is who can get access, how fast, and what comes back with each call.

Why people switch

Why developers stop waiting for Marketplace Insights

Approval can take forever, or never come

eBay grants Buy API production access to partners based on their business model, with no guarantee. CompSniper gives you a working key the same minute you sign up.

findCompletedItems is gone

The Finding API, which older tools used for sold items, was decommissioned in February 2025, and the Browse API only returns active listings. CompSniper fills that gap with one REST endpoint.

No category or marketplace allowlist

Search any keyword on any of 8 eBay marketplaces, with prices in each market's own currency, instead of only the categories eBay assigns you.

To be fair to Marketplace Insights: it is eBay's own first-party data, and if you are an approved eBay partner with access to the categories you need, it is a strong source. CompSniper is for everyone else who needs sold data now, without an application process.

The 5-minute version

One request instead of a partner application

Send a keyword with your API key and get real completed eBay sales as clean JSON, with the median and price range computed for you.

  • Live in about 5 minutes on a free key
  • Up to 240 sold listings per request
  • Optional AI cleanup before the median

Questions

Marketplace Insights API FAQ

What is the eBay Marketplace Insights API?+

It is eBay's Buy API for sold-item data. Its item_sales/search method returns the sales history of items for the last 90 days. It is marked Limited Release, and production access is limited to approved eBay partners.

Can I still apply for Marketplace Insights access?+

eBay says Buy API production access is for eBay partners, that you must apply, and that acceptance depends on your proposed business model with no guarantee. Many developers who apply never get access, which is why they look for an alternative.

What replaced findCompletedItems?+

eBay decommissioned the Finding API, including findCompletedItems, in February 2025 and pointed developers to the Browse API. The Browse API returns active listings, not sold ones, so there is no open eBay API for completed sales today.

What is the best Marketplace Insights API alternative?+

For most developers, a hosted sold-listings API. CompSniper returns up to 240 recent eBay sold listings per request as JSON across 8 marketplaces, with a free tier of 100 requests a month and paid plans from $9.

Does CompSniper need my eBay account?+

No. You do not need an eBay developer account, partner approval, or a seller account. You only need a CompSniper API key.
