Will this flag normal home users?

We combine ISP context with anomaly signals and return a confidence score, so you can set a threshold that minimises false positives.

Is it available via API?

Yes — residential proxy signals are part of the proxy verdict returned by GET /v1/proxy/{ip}.

Is there a free tier?

Yes, 100 lookups per month on the Free plan.

Residential Proxy Detection

Residential proxies look like real home users — that is the point. Our detection uses network reputation and pool intelligence to flag them anyway.

Overview

What is residential proxy detection?

Residential proxies route traffic through real consumer devices and ISP ranges, making automated and fraudulent traffic look like an ordinary home user. Because the IP belongs to a legitimate ISP, simple ASN or datacenter checks miss them. Residential proxy detection identifies IPs that are part of a residential proxy network using behavioural reputation, pool membership and shared-usage patterns rather than ownership alone.

Signals

How residential proxy detection works

These proxies hide in ISP space, so detection leans on reputation, not just ASN.

Pool intelligence

Cross-references IPs against known residential proxy provider pools.

Shared-usage patterns

A single home IP serving many unrelated sessions is a red flag.

Reputation history

How the address has behaved across our lookup network over time.

Velocity & rotation

Rapid IP rotation within an ISP range typical of proxy services.

ISP context

Combines ISP ownership with anomaly signals to avoid false positives on real users.

Confidence score

A 0–100 score lets you treat likely vs. certain proxies differently.
