Competitor Price Monitoring — Price Tracker for Ecommerce

📡 Competitor Price Monitor — Amazon & Bing Shopping Price Check by Product Name or URL

Competitor Price Monitoring is a NexGenData tool on Apify that returns product prices with changes since the last run from the e-commerce product pages you give it.

Pay-per-result price-check actor. Give it a product name and it searches Amazon (and Bing Shopping, when Bing answers) and returns every priced offer it finds — product name, price, list price, store, rating, review count, URL and ASIN — plus a summary (lowest, highest and average price) in the run's OUTPUT record. Give it product page URLs instead and it loads each page in a real browser and reads the price off the page; a page with no readable price is reported as unpriced and not billed. No subscription, no SKU cap, no seat licence: you pay $0.025 per priced offer delivered.

Real rows from run RJJWIsaL5OpRqJkpe on build 0.0.81 (2026-10-27), unedited apart from masked emails/phones and shortened long text; fields the source does not publish are empty.

⚙️ Sample inputs

This is the Store example input — the same input Apify's automated check runs — so it is proven to return rows on the current build. Paste it into the input form, or send it through the API, CLI or a schedule:

{
  "maxResults": 30,
  "productUrls": [
    "https://www.amazon.com/dp/B08N5WRWNW"
  ]
}

🔧 Input reference

Field	Type	Default	What it does
productName	string	""	Product name/keyword to search competitor prices for (use this or productUrls).
productUrls	array	["https://www.amazon.com/dp/B08N5WRWNW"]	Specific product page URLs to monitor (alternative to productName).
maxResults	integer	30	Maximum priced offers to return. Defaults to 10 as an evaluation-sized sample; raise it for full runs (each result is billed).

🧾 JSON sample record

One real record from run RJJWIsaL5OpRqJkpe (emails/phones masked, long text shortened):

{
  "productName": "Amazon Renewed WH-1000XM5/B Wireless Industry Leading Noise Canceling Bluetooth Headphones (Renewed)",
  "price": 179,
  "originalPrice": 228,
  "store": "Amazon.com",
  "domain": "www.amazon.com",
  "rating": "4.3",
  "reviewCount": null,
  "url": "https://www.amazon.com/dp/B0B2FCT81R",
  "asin": "B0B2FCT81R",
  "sponsored": false,
  "source": "amazon_search",
  "query": "Sony WH-1000XM5"
}

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$5e-05	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Price observation (apify-default-dataset-item)	$0.025	Single result in the default dataset.

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.025 = $2.50 plus the start fee.

🤖 Use with AI agents

Point Claude, the OpenAI Agents SDK, an n8n flow or any MCP-aware client at it and pull the data on demand.

This is a point-in-time price check, not a hosted dashboard: run it on a schedule and keep the datasets, and you have your own price history. It does not diff against the previous run for you.

What you get per offer

Each priced offer is a flat JSON record:

• productName, price, originalPrice (the list/strike-through price when the page shows one)
• store, domain, url, asin (Amazon offers)
• rating, reviewCount, sponsored (Amazon search results)
• source — amazon_search, bing_shopping or direct (a URL you supplied)
• query — the product name you searched

Every run writes a summary to its OUTPUT record (it is not a dataset row, so it is not billed) with totalResults, pricedResults, lowestPrice, lowestStore, highestPrice, averagePrice, the per-source status in sources, and unpricedSources (URLs that loaded but showed no price — not billed).

Use cases

• Shopify / D2C brands — check what Amazon and other stores are charging for your product today
• MAP-policy enforcement — spot offers under your minimum advertised price and keep the row as evidence (store, URL, price, run date)
• Amazon arbitrage / RA / OA — compare an Amazon offer against a supplier page by URL
• CPG analysts — sample list vs. sale prices across a category each week
• Retail buyers — benchmark competitor pricing before negotiating with suppliers
• Affiliate-content creators — refresh "best price today" tables on a schedule
• Founders — sanity-check launch pricing against incumbents

Quick start

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/competitor-price-monitor").call(run_input={
    "productName": "Sony WH-1000XM5",
    "maxResults": 25
})
summary = client.key_value_store(run["defaultKeyValueStoreId"]).get_record("OUTPUT")["value"]
print(f"{summary['pricedResults']} offers, lowest {summary['lowestPrice']} at {summary['lowestStore']}")
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["store"], item["price"], item["url"])

To check specific pages instead, pass "productUrls": ["https://www.amazon.com/dp/B0B2FCT81R", "https://www.bhphotovideo.com/..."] and leave productName empty.

Pricing

Pay-per-event — no SKU cap, no monthly minimum.

• Actor Start: $0.00005 per GB of memory (a fraction of a cent per run)
• Per priced offer: $0.025

A product-name search that returns 20 priced offers costs $0.50. Checking 500 product URLs once a day is about $12.50/day when every page shows a price — unpriced pages are free.

FAQ

Q: How does pricing differ from Prisync's SKU-cap model? We bill per priced offer delivered, not per SKU per month. Twenty offers for one product is $0.50; Prisync charges $99-249/mo regardless of how often you query.

Q: Can I diff against the previous run? Not inside the actor. Run it on a schedule, keep each dataset (or push rows to your own table with a webhook) and compare price by url or asin between runs.

Q: Can I plug this into Slack? Use Apify's built-in webhook integration. Set the trigger to "run succeeded" and POST the summary (OUTPUT record) or the dataset to your Slack incoming webhook URL.

Q: Which stores does it cover? By product name: Amazon search results, plus Bing Shopping offers from any store Bing lists (Bing sometimes returns none — the summary's sources says what each source answered). By URL: any retailer product page that shows a price in the HTML.

Q: Schema stability? The row fields above are fixed. When a retailer changes its page, prices come back as unpriced (not billed) rather than wrong.

How NexGenData Pricing Works

Every NexGenData actor uses pay-per-event pricing — you only pay for results that actually land in your dataset. No monthly minimum, no seat fees, no surprise overage bills.

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result / item: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform
