Competitor Price Tracker & Monitor — Compare Any Product URL Across the Web

Competitor price tracker that takes any product URL and finds every other retailer selling the same item, their live price, your rank in the market, and a suggested pricing action. Built for ecommerce sellers, brand managers, repricing teams, and MAP-policy enforcement who need to know who else sells this and for how much without searching Google by hand. Unlike Google Shopping scrapers, it returns verified product matches (UPC/EAN/GTIN + AI confirmation), drops mismatched-currency prices instead of guessing, and streams one clean row per competitor.

Paste a link from Amazon, Walmart, Target, Best Buy, eBay, Fnac, Shopify, WooCommerce or any independent store. The competitor price monitor handles the search, fetch, matching, and math for you.

• reference_availability — in-stock status.

Market aggregate

• matches_found — confirmed competitor matches for this product.
• urls_checked — SERP candidates fetched and classified.
• min_comp_price / avg_comp_price / max_comp_price — competitor price distribution.

Use cases

• ✓ Ecommerce sellers tracking competitor prices on Amazon and Walmart for their own SKUs
• ✓ Repricing teams flagging any retailer undercutting their floor price
• ✓ Brand managers enforcing MAP policy and spotting unauthorized resellers
• ✓ Dropshippers and arbitrage buyers finding the cheapest supplier per product
• ✓ Market researchers capturing the full price distribution, not just the top 3 results
• ✓ AI agents answering "what's the cheapest price online for X?" with fresh, grounded data

How it works

• Input: one or more canonical product URLs (e.g. https://www.amazon.com/dp/B08N5WRWNW). Each runs in parallel.
• Search: Google SERP per product, optionally narrowed to includedDomains and filtered against a social/review blocklist.
• Match: structured-data-first extraction, AI pre-filter, then fetch + AI classification with UPC/EAN/GTIN confirmation.
• Output: one row per confirmed competitor, streamed live to the Apify dataset — exportable to JSON, CSV, Excel, or the API.
• Scheduling & webhooks: run daily/hourly via Apify Schedules and push changes to Slack, Sheets, or your DB via webhooks.

Why this scraper

• Verified matches, not lookalikes — UPC/EAN/GTIN + AI confirmation, not fuzzy title guessing.
• Currency-safe — competitor prices in other currencies are dropped, never silently converted, so your numbers stay comparable.
• Major retailers covered — Amazon, Walmart, Target, Best Buy, eBay, Fnac and Cloudflare-protected stores via the scrape.do integration below.
• Resumable — re-running the same input picks up where it stopped, so no credits are wasted.
• Decision-ready — every row carries your rank, % vs market, and a suggested action.

The Scraper API Key (read this)

Without a Scraper API Key, the competitor price tracker fetches sites through residential proxy only. That works for small and mid-size shops but is reliably blocked by Amazon, Walmart, Target, Best Buy, Fnac, and eBay — you will get empty results for those.

Input example

{
  "productUrls": [
    { "url": "https://www.amazon.com/dp/B08N5WRWNW" }
  ],
  "scrapedoApiKey": "YOUR_SCRAPEDO_TOKEN",
  "country": "us",
  "currency": "USD",
  "maxCompetitors": 10,
  "maxPages": 2
}

Omit includedDomains to search the whole web, or set it to compare against a fixed list of retailers only.

FAQ

How does it get past anti-bot protection? Residential proxies for general stores, and the scrape.do API for Amazon, Walmart, Target, Best Buy, eBay and Cloudflare-protected sites.

What output formats are supported? JSON, CSV, Excel, and XML — exportable from the dataset tab or the Apify API.

Are the prices live or cached? Live. Every run fetches each competitor page in real time.

Does it work outside the US? Yes. Set country to any ISO code (gb, de, fr, ca, au, …) — both Google geo-targeting and the residential proxy follow.

Can I restrict which retailers it checks? Yes. Fill includedDomains to whitelist domains, or excludedDomains to skip ones that waste retries.

Can I track my own Shopify or WooCommerce store? Yes. Any public product URL works as the reference input.

Can I schedule it? Yes. Use Apify Schedules for daily/hourly runs and webhooks to push changes downstream.

Can I call it from an AI agent? Yes — see the next section.

Use via API or MCP

Run the competitor price monitor from any backend via the Apify REST API, or wire it into an AI agent (Claude, ChatGPT, Cursor) as an MCP server for grounded, real-time price answers.
