Poloniex API no longer accessible programmatically

[ielashi]

Looks like the Poloniex API is no longer accessible programmatically. I'll look into alternative APIs and will try to follow up with a pull request for this.

Did you mean you can't download training data?

[ielashi]

Yes, download requests give a 403 now because Poloniex added a CAPTCHA to the API calls.

[ZhengyaoJiang]

Really? I've also tried to download training data just now, nothing strange happened though.

Interesting. I just tried it through a US proxy and it works. I guess that's a regional restriction that Poloniex has rolled out. Never mind then.

@ielashi Because you are in a IP-flagged area. Try use a VPN. I need to use proxy as well and it works just fine. You can also check this for more ideas to bypass the restriction.

@ZhengyaoJiang Your area is not restricted so nothing happens. But in mainland China and some other areas the problem exists.

Since our work is reported by a Chinese news media. Here is a reference for future users who may need a proxy:

A quick fix looks like this (change line45-56 of poloniex.py)

import requests

    def api(self, command, args={}):
        """
        returns 'False' if invalid command or if no APIKey or Secret is specified (if command is "private")
        returns {"error":"<error message>"} if API error
        """
        proxies = {'http': 'socks5://127.0.0.1:1080', # socks5://<usr>:<pwd>@<addr>:<port>
                   'https': 'socks5://127.0.0.1:1080'} #use only if you are using **socks**

        if command in PUBLIC_COMMANDS:
            url = 'https://poloniex.com/public?'
            args['command'] = command
            return json.loads(requests.get(url+urlencode(args), proxies=proxies).text)
        else:
            return False

Edit:

Another way is to use transparent proxy, which is easier since no change of code needed.

Besides, you can use python-poloniex which supports private command as well. The latest version should cover proxy. You can check this as well.
