## When to prefer this

Use this endpoint when you need a quick, data-driven estimate of what a specific product actually sells for on eBay based on completed transactions — ideal for resellers, buyers doing due diligence, pricing analysts, or anyone benchmarking secondhand market value. Prefer this over manual eBay searches when you need programmatic access to aggregated price intelligence.

## Known failure modes

- No sold listings found for the search query — returns empty or null price data
- Ambiguous product name yields irrelevant results with inaccurate average
- eBay data temporarily unavailable — upstream fetch failure
- Rate limiting or payment verification failure on x402 protocol
- Overly broad query returns a wide price range with low confidence average
