Reusefulshop Used Item Price Estimator

Use this endpoint when you need a quick, structured price range (low/typical/high) for a second-hand item by name, especially when you want a confidence-annotated estimate rather than raw listing data. Prefer this over deal-check endpoints when you don't yet have a specific asking price to compare against, and over price-history endpoints when you want a current snapshot rather than a trend.

• Item query too vague or ambiguous leading to low-confidence or no estimate
• Item is too niche or rare with insufficient market data
• Malformed or missing 'q' query parameter returns validation error
• Item description yields no results if not recognizable in second-hand market data
