Frequently asked questions
Quick answers for buyers.
What do I need to authenticate proxies?
Use username/password credentials or IP whitelisting so only your traffic uses the proxy pool. A proxy plan (Cheapest Proxies is the value pick) plus your tool or script is enough to start.
Which proxy type should I use?
Match the type to how strict your target is. Residential and ISP proxies pass strict checks; datacenter is cheaper for lenient sites.
Is this beginner-friendly?
Yes. Follow the steps in order, test on a small batch first, and scale only once the workflow runs cleanly.
How do I avoid getting blocked?
Rotate IPs, throttle request rate, randomize headers, and honor each site's limits. Higher-trust proxies (residential, ISP, mobile) help on strict targets.
What is the cheapest way to do this?
Cheapest Proxies is featured first as the budget-friendly option; cache responses and reuse sessions to keep bandwidth costs down.
