Proxy Detection API
Proxy Detection API
Identify proxies and Tor exit nodes behind any IP address in real time. One endpoint covers HTTP, SOCKS, residential and datacenter proxies.
What is a proxy detection API?
A proxy detection API tells you whether an IP address is acting as an intermediary — an HTTP or SOCKS proxy, a residential proxy network, a datacenter proxy or a Tor exit node. IPScanner classifies the proxy type and returns a confidence score so you can decide whether to block, challenge or allow the request. It removes the need to maintain proxy blocklists yourself.
How proxy detection works
Different proxy types leak different signals — we look for all of them.
Open proxy fingerprints
Detection of exposed HTTP/HTTPS and SOCKS4/5 proxy endpoints.
Residential proxy networks
Identifies IPs sold through residential proxy pools despite looking like home connections.
Datacenter ranges
Hosting and cloud ASNs commonly used for proxying at scale.
Tor exit nodes
Live correlation against the public Tor exit list.
Header & latency anomalies
Forwarding headers and timing patterns typical of relayed traffic.
Proxy type & score
Each result names the proxy type and a 0–100 confidence value.
Where teams use it
Bot & scraping defense
Block scrapers that rotate through proxy pools.
Ad fraud
Filter invalid traffic coming from proxy infrastructure.
Account integrity
Catch multi-accounting hidden behind residential proxies.
Compliance
Verify the true origin of a request for KYC and licensing.
