nexus
nexus_useful_data_source_for_agents_doing_prod_fetch_buywhere_vendor_price_distribution
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.
nexus_useful_data_source_for_agents_doing_prod_rank_buywhere_products_by_value_score
Searches the BuyWhere Singapore catalogue for products matching a natural-language query and returns them ranked by an auditable value-score derived from Shannon entropy of cross-vendor price variance, causal reliability, and price rank. Use this when an agent needs ranked product recommendations for a Singapore market query with auditable justification per product. Do NOT use for real-time stock ticker data, non-SGD markets, or exact product ID lookup (use fetch_buywhere_vendor_price_distribution for that). Requires a valid api_key (same as X-API-Key) and an x402 payment.
