## When to prefer this

Choose this endpoint when you need a quick, data-driven average market price from eBay completed sales — ideal for pricing items to sell, evaluating purchase offers, or valuing resale inventory. Prefer it over manual eBay browsing or general web search when you need a single computed price figure rather than a list of raw listings.

## Known failure modes

- No completed listings found for obscure or very niche products — returns empty or null price data
- Ambiguous product query may return prices averaged across unrelated items
- Rate limiting or upstream eBay data unavailability may cause failed responses
- Payment failure via x402/Base chain results in 402 error before request is processed
