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

Returns a time-series array with one entry per day in the requested range, each containing: the date, the retailer's average price, the category-wide average price, a normalized price_index (retailer_avg / category_avg, where >1 means the retailer prices above category average), and a product count. Also includes top-level fields for retailer name, category, country, and currency code.

Example use cases

Example prompt

“Can you show me the day-by-day price index for Amazon in the electronics category in the US from January 1 to January 31, 2025 — I want to see how their pricing compares to the category average?”

When to prefer

Use this endpoint when you need to understand how a specific retailer's pricing positions relative to its category peers on a day-by-day basis — ideal for competitive pricing analysis, retailer benchmarking, or detecting when a retailer shifts pricing strategy. Prefer this over raw price history endpoints when you need a normalized, comparable index rather than absolute prices. Best for analysts monitoring whether a retailer is a price leader or price follower within a category.
