eBay Dataset API
Auction listings, buy-it-now prices, seller ratings, and bidding data from the global online auction platform.
Available Data
Here's what you can extract from eBay using AlterLab:
Business Use Cases
How businesses use eBay data to make better decisions:
- Reseller arbitrage research across markets
- Pricing used goods before listing for sale
- Market value research for collectibles and vintage items
- Competitive pricing intelligence for retail categories
- Cross-market pricing research for electronics and apparel
How It Works
Provide an eBay listing or search URL
Send any eBay item URL, search result page, or sold listings URL to AlterLab. eBay's item URLs include a stable item number — you can construct these directly or use search results to discover new listings.
AlterLab fetches the live listing data
Unlike Amazon or Walmart, eBay does not deploy aggressive bot detection systems like Cloudflare or custom challenge pages. Most eBay listing pages load reliably without complex challenge resolution — making eBay data faster and cheaper to collect at scale than most major e-commerce platforms.
Get structured auction and pricing data
Receive item details, current bid price or fixed price, time remaining, seller feedback score, shipping costs, and item condition — all in structured format ready for your pricing models or market research tools.
Key Insight
eBay's sold listings history (accessible by adding LH_Sold=1 to search URLs) is one of the most reliable sources of actual transaction prices for consumer goods. Unlike active listings, sold prices reflect what buyers actually paid — invaluable for pricing used goods, collectibles, or resale inventory.
Data Freshness
Active auction prices change with each bid. For auctions, monitor 6-hourly. For sold listing market research, weekly collection is sufficient as pricing trends shift gradually.
