Intersango API python interface

[phantomcircuit]

This is a very basic framework for the intersango API in python.

Edit: updated to support states filter for orders
Edit: added support for fill or kill and immediate or cancel orders

Code:

import httplib
import urllib
import json
import decimal
import threading
import socket

class intersango:
    version = "0.1"
    
    good_til_cancelled = 'gtc'
    fill_or_kill = 'fok'
    immediate_or_cancel = 'ioc'
    
    def __init__(self,api_key):
        self.api_key=api_key
        self.connection = None
    
    def connect(self):
        if self.connection is None:
            self.connection = httplib.HTTPSConnection('intersango.com')
    
    def make_request(self,call_name,params):
        params.append(('api_key',self.api_key))
        body = urllib.urlencode(params)
        
        self.connect()
        
        try:
            self.connection.putrequest('POST','/api/authenticated/v'+self.version+'/'+call_name+'.php')
            self.connection.putheader('Connection','Keep-Alive')
            self.connection.putheader('Keep-Alive','30')
            self.connection.putheader('Content-type','application/x-www-form-urlencoded')
            self.connection.putheader('Content-length',len(body))
            self.connection.endheaders()
            
            self.connection.send(body)
            
            response = self.connection.getresponse()
            
            return json.load(response)
        except httplib.HTTPException:
            self.connection = None
            return False
        except socket.error:
            self.connection = None
            return False
        
    def list_accounts(self):
        return self.make_request('listAccounts',dict())
    
    def list_orders(self,account_id,last_order_id=None,states=None):
        params = [('account_id',account_id)]
        
        if last_order_id is not None:
            params.append(('last_order_id',last_order_id))
        
        if states is not None:
            for state in states:
                params.append(('states[]',state))
        
        return self.make_request('listOrders',params)
    
    def list_deposits(self,account_id):
        return self.make_request('listDeposits',[('account_id',account_id)])
    
    def list_withdrawal_requests(self,account_id):
        return self.make_request('listWithdrawalRequests',[('account_id',account_id)])
    
    def place_limit_order(self,quantity,rate,selling,base_account_id,quote_account_id,order_type=good_til_cancelled):
        params = []
        assert type(quantity) == decimal.Decimal
        assert type(rate) == decimal.Decimal
        
        params.append(('quantity',quantity))
        params.append(('rate',rate))
        params.append(('selling',str(selling).lower()))
        params.append(('base_account_id',base_account_id))
        params.append(('quote_account_id',quote_account_id))
        params.append(('type',order_type))
        
        return self.make_request('placeLimitOrder',params)
    
    def request_cancel_order(self,account_id,order_id):
        return self.make_request('requestCancelOrder',[('account_id',account_id),('order_id',order_id)])

b = intersango('your api key goes here')
b.place_limit_order(decimal.Decimal('10'),decimal.Decimal('2.49051'),True,1,2,intersango.immediate_or_cancel)

Best!

What is the account_id? Is it the e-mail address associated with an account?

[phantomcircuit]

account_id is the account number found on the accounts page, they're also available via the listAccounts.php API call.

[runeks]

Ah, cool, thanks.

I assume you have something to do with Intersango because of your signature. So I'll ask you my important question.

I just transferred some Bitcoins to Intersango and purchased some US dollars for them. Now I have some US dollars in my account, but since I am not allowed to register an account at Dwolla (they only accept US citizens as account holders) I don't have a way to withdraw the money.

Is there no way for me to get my money back from you?

[phantomcircuit]

We can probably accommodate you, of course it depends on what you can accept.

Make a proposal and we'll think about it.

[genjix]

runeks, you should open a ticket on Intersango by emailing support@intersango.com and then someone will respond to solve your issue. It's better that way as we can better track tasks and assign them to the correct people appropriately.

[runeks]

OK, I have done that. You might want to add a notice somewhere that your site is only designed (at the moment) for US customers, so others don't get in the same situation that I am in.

Where did you get that idea? Our offices are in London, and we have accounts for British GBP, European EURO and Polish Zloty.

Info: https://intersango.com/fees.php

We aren't allowed to let people easily convert between funds as that's forex trading.

I've updated the example to show filtering for the listOrders call

My mistake. I got the impression that withdrawals were only possible via Dwolla.

Is it possible for me to deposit USD (and not EUR) to my Intersango account via a European bank transfer (SEPA)?

It should be possible, but you'll need to pay the bank's conversion fees. Email support@intersango.com and they'll fill you. List your country and bank name and they should be able to guide you through.

I have updated the example to include support for FOK and IOC orders.

Does anyone know the format of the last_trade_date parameter? microseconds since the GMT epoch (1.1.1970) , or so?

Seconds since epoch as an integer (no microsecond precision).

This is a very basic framework for the intersango API in python.

Cool ... maybe now someone can code up even more bots to outbid me by 0.0001 BTC every time I leave an order on that exchange

[daybyter]

Note to myself....must add a line: if( highest_bid( "Intersango").getUser().equals( "toffoo")) { break; } ...
