Please note that the API only works for getting new proxy from "ProxyList", and can not be used to reuse the proxy from "TodayList". The following are how to use the API and examples
After login to the software, switch to AutoProxy tab, select "Use API" from "API settings" and you need to keep the software staying logged in when you use the API:
In the software's root folder, there's a sub folder: "proxytool" and there's a file "Autoproxytool.exe" in it
Using your soft/script which want to implement the api to launch "Autoproxytool.exe" with the following parameters, then you are able to change proxy automatically:
Autoproxytool.exe -changeproxy/all - use a random proxy from any countries
Autoproxytool.exe -changeproxy/US - use a random proxy from US
Autoproxytool.exe -changeproxy/US/NY - use a random proxy from US, state: NewYork
Autoproxytool.exe -changeproxy/US/NY/"New York" - use a random proxy from US, state: NewYork, city: New York
For country you need to enter the country ISO alpha-2 code, if you have no idea, you can google: country ISO alpha-2 code
-citynolimit
Autoproxytool.exe -changeproxy/US/NY/"New York" -citynolimit
Which means the API system will firstly try to get a proxy from the City you set(New York) for higher priority, Only if there's no proxy available from that City, then it will try to get a proxy from the State you set(NY).
-ip=
Autoproxytool.exe -changeproxy/ -ip=123.123.123.123
Autoproxytool.exe -changeproxy/ -ip=123.123.*.*
Autoproxytool.exe -changeproxy/ -ip=123.*.*.*
Get a proxy by ip. You can replace * in the ip address to get any proxy from that ip block, e.g:
-proxyport= / -freeport=
Autoproxytool.exe -proxyport= - Forward a proxy to a port
Autoproxytool.exe -freeport= - Free the port and unload the proxy
Autoproxytool.exe -changeproxy/US/NY/"New York" -proxyport=5000
Autoproxytool.exe -changeproxy/US/NY -proxyport=all
Autoproxytool.exe -changeproxy/US/NY -isp="Time Warner Cable"
Autoproxytool.exe -changeproxy/US -zip=92626
Autoproxytool.exe -changeproxy/US/NY -isp="Time Warner Cable" -proxyport=5000
Autoproxytool.exe -changeproxy/US -zip=92626 -proxyport=5000
With using -hwnd= parameter, Autoproxytool.exe will send WM_COPYDATA message to your soft which launches Autoproxytool.exe, so that your soft is able to get postcheck and more info of the proxy, you also need to pass the Window Handle of your soft which launches Autoproxytool.exe
Autoproxytool.exe will send you WM_COPYDATA message with the following format and info:
If the proxy successful get by api:
success|ip|Ping|ProxyCountry|ProxyState|ProxyCity|911s5 account balance
If the proxy failed to get by api:
failed|reason for failure
Examples:
Autoproxytool.exe -changeproxy/US/NY/"New York" -hwnd=YOUR SOFT'S WINDOW HANDLE
Autoproxytool.exe -changeproxy/US/NY/"New York" -citynolimit -hwnd=YOUR SOFT'S WINDOW HANDLE
Autoproxytool.exe -changeproxy/ -ip=123.123.*.* -hwnd=YOUR SOFT'S WINDOW HANDLE
In "AutoProxy" tab, the features of "AutoProxy Settings" its not for API, its designed for auto swiching proxy according to the configs, you can set the frequency to auto change proxy and set delay of time range to auto launch your program, etc. For using this feature, you need to unselect "Use API" from "API Settings"
Since 911 S5 3.2, We developed a new API program for port forwarding
The new API program works with multi-thread, you can send multiple API requests at the same time (The old API program Autoproxytool.exe only can handle your request one by one with single thread, you have to wait until the last request get processed)
If your work requires high efficiency which need to send a lot of API requests, we suggest you to use the new API:
In the software's root folder, there's a sub folder: "proxytool" and there's a file "ProxyAPI.exe" in it
Launching "ProxyAPI.exe" with parameters from your soft/script, the parameters and format its exactly the same like using the old API program (Autoproxytool.exe), the only difference is you need to include this parameter -proxyport=, the port behind this parameter must be in the "Port Forward" range of 911 S5's "Settings" tab.
Please note, you need to keep 911 S5 staying logged in when you use the API.
