Why

Why Price monitoring needs a proxy

Shops show different prices, currencies and shipping costs depending on where you connect from. Opening the same product often from one IP can also get your requests blocked. Spreading requests across home IPs by country gets you the local price and keeps requests evenly spread.

Repeated requests from one IP

  1. Request 1198.51.100.7
  2. Request 2198.51.100.7
  3. Request 3198.51.100.7

Requests spread across several home IPs

  1. Request 1203.0.113.11
  2. Request 2203.0.113.27
  3. Request 3203.0.113.42
The IP addresses shown are examples.
