web interface / proxycheck.io

General Information

Below you can paste in one or more addresses to be tested against the proxycheck.io API. The limit is 10,000 addresses or 90 seconds processing time (whichever comes first), each address must be seperated in some way but miscellaneous text around the addresses will not matter. Using your API key is optional, without one you will be limited to 100 free checks per day.

If you're logged into our dashboard your API Key will be supplied below automatically. All queries made into the web interface accure against your API Key the same way that API queries do.
