| api_key | secret token which you submit alongside with the request |
| tested_url | the URL of the domain to be tested. |
| dnsr | "on" means that test results will be hidden, "off" means that test results will be displayed in statistics. |
| choosen_ip | IP address of tested server (if tested domain resolves to multiple addresses). |
| recheck | "false" will use results from cache if the server has been tested within the past 24 hours, "true" will perform a new test without looking at the cache. |
