Tool of io.github.nexus-mcp-infra/useful-data-source-for-agents-doing-product-price-sdk

declared in 1.28.1

Given a BuyWhere product identifier, returns the full cross-vendor price distribution in SGD along with the Shannon entropy of that distribution and the coefficient of variation. Use this when an agent already knows the product and needs to audit price fairness or detect outlier vendor pricing. Do NOT use as a discovery tool — it requires a known BuyWhere product_id from rank_buywhere_products_by_value_score. Requires a valid api_key (same as X-API-Key) and an x402 payment.
