E-commerce Price Monitoring
Track competitor prices and product availability across hundreds of e-commerce sites.
Quick Answer
Point CrawlForge batch_scrape (5 credits) at hundreds of competitor product URLs to pull prices and availability in parallel, then track_changes (3 credits) to flag every price or stock shift automatically. You get alerts when competitors move instead of re-checking pages by hand -- a daily sweep runs comfortably inside a Hobby or Professional plan.
The Problem
E-commerce teams need to monitor competitor pricing across hundreds of product pages daily. Manual checks do not scale, and traditional scrapers break when sites update their layouts.
The Solution
CrawlForge batch_scrape processes hundreds of URLs in parallel, while track_changes detects price and availability shifts automatically. Get alerts when competitors change pricing.
Code Example
// Monitor competitor prices across product pages
const products = await mcp.batch_scrape({
urls: [
"https://competitor-a.com/product/widget-pro",
"https://competitor-b.com/products/widget-pro",
"https://competitor-c.com/shop/widget-pro",
],
selectors: {
price: ".product-price",
availability: ".stock-status",
title: "h1.product-title",
},
});
// Track changes since last check
const changes = await mcp.track_changes({
url: "https://competitor-a.com/product/widget-pro",
selectors: [".product-price", ".stock-status"],
});
console.log(changes.diff);Tools Used
Estimated cost: ~8 credits per batch of URLs
Frequently Asked Questions
How do I monitor competitor prices across hundreds of product pages?
Use CrawlForge batch_scrape to pull hundreds of URLs in parallel, then track_changes to watch each page and flag price or availability shifts automatically. You get alerts on changes instead of re-checking pages by hand.
Does price monitoring break when a store changes its layout?
Less often than with brittle CSS scrapers. scrape_structured targets stable selectors and extract_content falls back to readable extraction, so minor layout changes do not silently break your feed. When a selector does drift, only that template needs updating.
How much does automated price tracking cost in credits?
batch_scrape is 5 credits per call and track_changes is 3 credits. A daily sweep of a few hundred products typically runs comfortably within the Hobby or Professional monthly credit allowance.
Can I get alerted only when a price actually changes?
Yes. track_changes stores a baseline for each page and reports diffs on a schedule, so you are notified only when a price or stock status actually moves — not on every crawl.
