Proxy checker API

GET or POST https://hproxy.com/api/proxy-check runs a real live test on any proxy: alive, protocols, anonymity, latency and location. Free, no key.

Check one proxy

Check whether a proxy is alive and get its protocols, anonymity grade, latency and location. Free, no key, CORS enabled. Each request runs a real live test against the proxy (a dead one can take a few seconds to report), so it is rate limited more tightly than the list: bursts of 10, refilling to about 12 checks per minute per IP, with a 429 + Retry-After beyond that. Geo and ASN fields fill in when enrichment data exists and are null otherwise.

ParameterTypeRequiredDescription
proxyip:port (query)requiredThe proxy to test, e.g. 203.0.113.7:1080.

Check up to 25 at once
