How this service works
Real-time pricing, promotions, and competitive intelligence across US and Canadian retailers — exposed as paid API endpoints and MCP tools that AI agents can call directly, with x402 and MPP micropayments per query.
Output
A time-series array indexed by date, where each entry contains the brand's average price, minimum price, maximum price, total product count, in-stock product count, and promotional product count for that day. Also returns the brand name, country, and ISO 4217 currency code.
Example use cases
Example prompt
“Can you pull the day-by-day price and stock stats for Nike on Amazon in the US from January 1 to January 31 — I want to see the average, min, and max price, how many products were in stock each day, and how many were on promo?”
Technical details
Endpoint
GEThttps://api.crushrewards.dev/v1/marketing/brand-trackerWhen to prefer
Use this endpoint when you need to track a specific brand's pricing and availability trends over time (day-by-day granularity), optionally filtered to a specific retailer or country. Prefer this over category-level endpoints when the focus is a single brand's historical performance rather than cross-brand or category-wide comparisons.
