Real-Time Price Aggregation
Without Boundaries

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.

High-Frequency Rotation

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

Hyper-Local Pricing

Compare public catalog pages from selected cities or ZIP codes where that targeting is available and permitted.

zero CAPTCHA Triggers

Our residential IPs have the highest trust scores (ISP-assigned). Say goodbye to annoying CAPTCHAs and 403 Forbidden errors.

COMMON QUESTIONS

Price Aggregation FAQ

How does rotating residential proxies help with price scraping?

E-commerce platforms track IP activity. If one IP makes too many requests, it gets blocked. PreProx rotates your IP for every request or session, making your scraper appear as thousands of different real customers.

Can I target specific marketplaces in Europe or Asia?

Choose from current country inventory and use more precise regional targeting where available. Availability should be confirmed in the dashboard before purchase.

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

No. Our residential proxy plans are based on data usage (GB), not requests or IPs. You can connect as many scrapers as you want simultaneously.

Do the proxies work with Headless Browsers like Puppeteer?

Common tools such as Puppeteer, Playwright, Selenium, and Scrapy support proxy configuration. Confirm that your selected tool supports the endpoint protocol and authentication format before scaling.

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.
