Use case

Track prices, stock and delivery promises across European storefronts as local shoppers see them, including country-specific prices and VAT.

Rotating residential Rotating per request, country targeting

## The problem

Retailers show different prices, currencies, promotions and delivery dates depending on the visitor's country, and many protect product pages against automated collection.

Reliable monitoring needs requests from residential addresses in each market, spread over time so that daily checks of thousands of products stay below anti-bot thresholds.

## Configuration

**Product**
Rotating residential, billed per GB

**Rotation**
Per request

**Targeting**
-country-<cc> per storefront (de, fr, es, it…)

**Scheduling**
Spread checks over the day instead of one nightly burst

**Payload**
Prefer product JSON endpoints or structured data over full pages

**Typical volume**
A product page weighs 0.5–2 MB uncompressed; compression divides it several times

## Example

Python Copy

```python
import requests

LOGIN, PASSWORD = "px7h2k9m4q", "Rq4Tn8Vw2Lx6Bz9C"
STOREFRONTS = {
"de": "https://shop.example.de/p/4011",
"fr": "https://shop.example.fr/p/4011",
"es": "https://shop.example.es/p/4011",
}

for country, url in STOREFRONTS.items():
proxy = f"http://{LOGIN}-country-{country}:{PASSWORD}@resi.gw.proxuno.com:7000"
r = requests.get(
url,
headers={"Accept-Encoding": "gzip, br"},
proxies={"http": proxy, "https": proxy},
timeout=30,
)
print(country, r.status_code, len(r.content))
```

Example credentials. Replace them with yours from the dashboard.

## Best practices

- Target the storefront's own country; cross-border visits often trigger redirects or different prices.
- Fetch structured data (JSON-LD, product APIs used by the page) to cut traffic per product.
- Detect soft blocks — a 200 response with a CAPTCHA page — and count them as failures.
- Keep a per-domain request budget and adjust it to the observed success rate.

Compliance

Collect public product information only. Do not create fake orders or hold stock in carts, and respect the retailer's terms of use.

Alternative

[Static ISP](/static-residential-proxies)

Static ISP proxies are a better fit when you monitor through a logged-in account (B2B portals, marketplaces' seller views) that must keep one IP.
