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 JSON object with the matched product name, retailer, currency, current price, period low/high/average prices, a trend enum (rising/falling/stable), a boolean good-deal flag, and a dated time-series array of price observations suitable for charting.
Example use cases
Example prompt
“Can you pull up the price history for 'Sony WH-1000XM5 headphones' on Amazon in the US from January 1 to June 30 this year, and tell me if it's currently a good deal based on the trend?”
Technical details
Endpoint
GEThttps://api.crushrewards.dev/v1/shopper/price-historyWhen to prefer
Use this endpoint when you need historical price data and trend analysis for a specific product at a specific retailer, including whether the current price is a good deal relative to its history. Prefer this over category-level or brand-level endpoints when the user has a specific product in mind and wants a time-series for charting or a buy/wait recommendation.
Side effects
- No matching product found for the query — returns empty or null result
- Invalid date format (non-ISO 8601) causes a 400 validation error
- Unsupported retailer or country code causes a 400 validation error
- Query string too short or missing causes a 400 required-field error
- Payment not processed or x402 header missing causes a 402 Payment Required error
- Date range with no historical data returns an empty observations array
