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 the matched product name, retailer, country, currency, current price, rolling average price over the configured lookback window (field named avg_price_last_30d for backwards compatibility), the percentage difference between current and average price, a boolean is_price_drop flag, and the all-time lowest seen price along with the date it occurred.

Example use cases

Find laptop deal vs history

“Is the current Best Buy price for the Dell XPS 15 laptop actually a deal right now, or is it just normal pricing? Compare it against its rolling average from the last 30 days and tell me if it's dropped below that — I also want to know the lowest it's ever been.”

Walmart item rolling average check

“Check whether the Instant Pot Duo 7-in-1 on Walmart.com in the US is priced below its 60-day rolling average right now — I'm trying to figure out if this is a genuine discount before I buy it today.”

Canadian retailer price drop alert

“Look up the current price of the Ninja Creami ice cream maker at a major Canadian retailer and tell me if it's fallen below its recent average — I want the is_price_drop flag, the percentage difference, and the all-time lowest price it's ever hit.”

When to prefer

Use this endpoint when you need to determine in real time whether a specific product's current price represents a genuine discount relative to its recent price history, especially when you need the is_price_drop boolean flag, percentage deviation from average, and all-time lowest price in one call. Prefer this over generic price history endpoints when the goal is deal-detection rather than raw historical data.

Side effects

Retailer not supported for the given country — enum mismatch error
lookback_days out of range (below 1 or above 365) — validation error
Insufficient price history for the lookback window — may return null average
Payment not completed (x402) — 402 Payment Required before data is returned
