Price Monitor — Amazon, Walmart, eBay, Target, Best Buy Tracker

Monitor product prices across Amazon, Walmart, Target, eBay, and Best Buy. Extract prices, availability, ratings, and images. Track price history and identify competitive pricing opportunities for e-commerce intelligence.

How It Works

The actor takes a product name (and optional UPC) and runs a targeted Playwright crawler against each selected retailer's search results page. For every matching listing it extracts the product title, URL, current price, currency, availability, rating, review count, seller, and shipping estimate, then aggregates the rows from all retailers. Results are sorted by price ascending so the lowest offer surfaces first, and the actor writes a summary of the lowest, highest, and average price to the key-value store for trend tracking across scheduled runs.
