## When to prefer this

Choose this endpoint when you need structured eBay product data — prices, conditions, and links — without managing an eBay API key or developer account. Ideal for price comparison, reseller research, or marketplace monitoring where eBay is specifically the target platform. Prefer over general web scraping when you need clean, JSON-formatted eBay results with minimal setup and pay-per-call pricing.

## Known failure modes

- Invalid or unsupported eBay domain returns an error
- Unrecognized category_id may return empty or incorrect results
- Malformed popular_filters string causes filter parsing failure
- No results found for very niche or misspelled search keywords
- Rate limiting or service unavailability returns a non-200 response
