Location-Aware Price Aggregation
For Public Catalog Research

Monitor authorized public pricing pages across selected markets. PreProx provides rotating and sticky residential sessions, while each marketplace controls access and permitted request rates.

Why Use PreProx for Price Comparison?

Use rotating or sticky residential sessions to review authorized public catalog data from selected locations while respecting each site's access rules.

Configurable Rotation

Configure rotation per request when your collection workflow does not require a persistent session.

Location-Based Comparisons

Choose available country, state, city, ZIP code, and ASN options for public catalog checks. Displayed prices may also depend on account, currency, cookies, and delivery settings.

Track Access Responses

Destinations may return challenges, rate limits, or access errors. Monitor status codes and test a small permitted sample before expanding collection.

import os
from urllib.parse import quote
import requests

host = os.environ["PREPROX_PROXY_HOST"]
port = os.environ["PREPROX_PROXY_PORT"]
username = quote(os.environ["PREPROX_PROXY_USERNAME"], safe="")
password = quote(os.environ["PREPROX_PROXY_PASSWORD"], safe="")
proxy_url = f"http://{username}:{password}@{host}:{port}"
target = os.environ.get("TARGET_URL") or "https://example.com/"

try:
    with requests.Session() as session:
        session.trust_env = False
        session.proxies = {"http": proxy_url, "https": proxy_url}
        with session.get(target, timeout=(10, 30)) as response:
            response.raise_for_status()
            print(f"HTTP {response.status_code}")
except requests.RequestException:
    raise SystemExit("Request failed; check the endpoint and target.")

Test Your Catalog Collection Settings

Measure response rates, page sizes, and GB usage on a small product sample. Expand within destination limits and your application capacity. Choose timed rotation in whole-minute intervals from 1 to 120 minutes, or sticky mode with no scheduled rotation. A sticky IP can still change if its residential peer disconnects or the targeting changes.

Install Requests with python -m pip install requests. Select an HTTP-capable endpoint for this example and set PREPROX_PROXY_HOST, PREPROX_PROXY_PORT, PREPROX_PROXY_USERNAME, and PREPROX_PROXY_PASSWORD from the dashboard. Copy the complete generated username and password without removing targeting parameters. Set TARGET_URL to a permitted catalog URL, or leave it unset to check https://example.com/.

COMMON QUESTIONS

Price Aggregation FAQ

How does rotating residential proxies help with price scraping?

Configure timed rotation from 1 to 120 whole minutes or a sticky session without scheduled rotation in the dashboard according to your workflow. Rotation changes the network path, but marketplaces can still impose rate limits, challenges, and access restrictions.

Can I target specific marketplaces in Europe or Asia?

Choose country, state, city, ZIP code, and ASN options from current inventory. Confirm availability in the dashboard before purchase and check that the marketplace permits your collection workflow.

Is there a limit on how many products I can monitor?

Residential proxy billing is based on consumed GB rather than product count. Practical coverage depends on your traffic balance, page sizes, destination limits, and application capacity. Choose concurrency based on measured responses.

Do the proxies work with Headless Browsers like Puppeteer?

Tools such as Puppeteer, Playwright, Selenium, and Scrapy support proxy configuration. For browser examples with username and password authentication, choose an HTTP-capable endpoint and confirm your tool supports its authentication settings.

Does PreProx guarantee access to Amazon or eBay?

No. Marketplace access depends on the IP, request pattern, account context, and each site's policies. Test a small permitted workflow and track your own response and retry rates.
