Price monitoring needs the price a local shopper sees, on a schedule, without blocks. Datafuel offers residential proxies for the scraper you already run, or the Unlocker API that returns product pages as JSON. Only successful requests are billed.
Why price monitoring is hard to do at scale
Merchant feeds tell you what a retailer says the price is. The page tells you what it actually is, right now, for a shopper in a specific place. Those two numbers disagree more often than anyone expects.
Getting the page is the hard part. Marketplaces block datacenter IPs on sight and rate-limit anything that looks automated. Prices vary by country and sometimes by city. And catalogues change continuously, so a weekly pull is a snapshot of a market that has already moved.
A monitoring feed with gaps is worse than no feed: a competitor's price drop you missed is a decision made on wrong information.
How Datafuel handles price monitoring
Datafuel's residential network puts your monitoring on IPs that belong to real households, targeted to the country and city you care about. A retailer sees a local shopper, and returns the price a local shopper gets.
For marketplaces behind heavy protection, the Unlocker API takes the URL and returns the price, stock and promotion fields as structured JSON. Scheduled monitoring runs on the cadence you set and flags changes, so you learn about a price move when it happens.
Keep your collector and fix the network, or hand us the URL. Same IPs, same billing rule.
| Residential proxies | Unlocker API | |
|---|---|---|
| You bring | your own scraper and parser | a URL, and a schema if you want JSON |
| You get | the raw page from a local residential IP | Markdown or structured JSON, past any protection |
| Targeting | country · region · city · ASN · OS | country and city, per request |
| CAPTCHAs | handled by your scraper | handled inside the request |
| Billing | per GB, traffic never expires | per successful request, credits never expire |
| Best when | you already run a working scraper | you want pages without maintaining a parser |
Many teams use both: the API for the pages that block, proxies for the collectors they already run.

How it works
- 01Define your competitor set, SKUs, regions and cadence.
- 02Datafuel collects each page from a residential IP in the target location, or through the Unlocker for protected marketplaces.
- 03Price, stock and promotion fields return as structured data, with change alerts when something moves.
What to watch for
- Currency, tax and shipping change the comparable price. Normalise before you compare.
- Variants matter. A product page may show a base price while the variant a shopper buys costs more.
- Match your cadence to how fast the category moves. Electronics change daily; furniture changes monthly.
