Real market pricing,
one endpoint away
You want to ship a price tracker, a valuation feature, or a resale calculator. You do not want raw search matches where iPhone 17 Pro Max includes cases and chargers. CompSniper is a single REST endpoint that returns cleaned, versioned JSON so you can build the feature and move on.
100 free requests every month. No credit card required.
eBay's own APIs are a dead end
The Finding API was decommissioned, and Marketplace Insights, the one official source of sold data, is a Limited Release that is not accepting new developers. That leaves you scraping, and scraping is a maintenance treadmill.
- Self-scraping means proxies, CAPTCHAs, and parsers that break the day eBay ships new HTML.
- Raw keyword results need relevance cleanup before they are safe to turn into a median.
- OAuth flows and XML envelopes turn a simple lookup into a week of integration work.
- Every hour you spend on data plumbing is an hour not spent on your actual product.
From keyword to data in three steps
Authenticate with a bearer key
Grab your cs_ key from the dashboard and pass it in the Authorization header. No OAuth handshake, no token refresh, no client secrets.
Call one GET endpoint
Hit /v1/scrape with a keyword and optional filters. AI relevance is on by default, so noisy matches are removed before your app uses the sample.
Parse cleaned, typed JSON
Get a predictable envelope with an items array of 26 typed fields each. Prices are decimal strings, and the sample is already cleaned for relevance.
One request.
Real sold prices back.
Search rtx 4090 founders edition and get up to 240 completed sales, cleaned by a custom AI model before you use the median. Each result includes 26 data fields: sold price, shipping, condition, sold date, seller rating, and more.
- 26 fields per item
- Everything you need to price accurately, returned as clean JSON after noisy matches are removed.

Integrate in an afternoon
One endpoint, bearer auth, cleaned JSON. If you can call an HTTP API, you can ship real pricing today.
Cleaner medians out of the box
The custom AI model removes accessories, parts, and wrong models before your app calculates or displays the price.
A stable, versioned contract
Everything lives under /v1. When eBay changes their HTML, we ship the parser fix. Your integration never notices.
8 marketplaces, one shape
US, UK, DE, FR, IT, ES, CA, and AU all return the same envelope, so you write your parser once.
