{"name":"materials-price-check","description":"Supply/materials price check: shopping-intent retail listings with detected prices, a web search for bulk/wholesale pricing context, and (when a non-USD currency is requested) an fx reference rate, in one call. Composite: one call runs product-search as the required leg, then search and (when needed) exchange-rates in parallel as optional legs, so a miss on either degrades the response instead of failing the call. Use it as a materials or supply price check for agents doing procurement or cost research.","price":"$0.05","method":"POST","input_schema":{"properties":{"material":{"type":"string","description":"Material or supply item to price-check, e.g. 'galvanized steel sheet' or 'plywood 4x8'.
