eBay Data Extraction

Extract publicly available data from eBay at scale using AlterLab's API — JavaScript rendering, structured extraction, and automatic retries in one request.

Automatic renderingJavaScript supportStructured data extractionChallenge resolution

Website Compatibility Notes

eBay has relatively light protections for product and listing pages. Most pages are accessible with standard browser rendering. JavaScript rendering improves data completeness for auction details, Q&A sections, and seller information panels. Rate limiting applies at scale — spreading requests over time is recommended. Sold listings and completed auctions require the same approach as active listings.

Technical Context

eBay item URLs follow a consistent pattern: ebay.com/itm/{item_id}. Search result URLs include filters as query parameters. eBay's sold/completed listings are accessible at ebay.com/sch/... with the LH_Complete=1&LH_Sold=1 parameters — these provide historical pricing data. The item detail page renders product specifications and seller information without complex anti-bot measures.
