Real market pricing,
one endpoint away
You want to ship a price tracker, a valuation feature, or a resale calculator. You do not want to run headless browsers, rotate proxies, or reverse-engineer eBay's markup every quarter. CompSniper is a single REST endpoint that returns clean, 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.
- OAuth flows and XML envelopes turn a simple lookup into a week of integration work.
- Rate limits and bans make a homegrown scraper fragile in production.
- 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. Standard query params, standard HTTP status codes, standard rate-limit headers.
Parse clean, typed JSON
Get a predictable envelope with an items array of 26 typed fields each. Prices are decimal strings so you never lose precision.
One request.

Integrate in an afternoon
One endpoint, bearer auth, clean JSON. If you can call an HTTP API, you can ship real pricing today.
A stable, versioned contract
Everything lives under /v1. When eBay changes their HTML, we ship the parser fix. Your integration never notices.
Predictable status codes and headers
400, 401, 429, and 5xx behave the way you expect, with Retry-After and X-RateLimit and X-Usage headers on every response.
8 marketplaces, one shape
US, UK, DE, FR, IT, ES, CA, and AU all return the same envelope, so you write your parser once.
