Also works with the [original exchange server](http://github.com/viabtc/viabtc_exchange_server). 3 | 4 | [](https://morejust.foundation/?from=python-viabtc-api) 5 | 6 | ## Installation 7 | 8 | This API is very simple. The installation is just the downloading sources from github 9 | 10 | ``` bash 11 | git clone https://github.com/testnet-exchange/python-viabtc-api 12 | cd python-viabtc-api 13 | pip3 install -r requirements.txt 14 | ``` 15 | 16 | ## Usage 17 | 18 | The basic usage: 19 | 20 | ``` python 21 | from ViaBTCAPI.ViaBTCAPI import ViaBTCAPI 22 | 23 | exchange_url = "http://localhost:8080/" # choose to your exchange url 24 | api = ViaBTCAPI(exchange_url) 25 | 26 | resp = api.market_list() 27 | market_names = [m["name"] for m in resp["result"]] 28 | print("Exchange markets: ", market_names) 29 | 30 | print() 31 | print("Orderbooks:") 32 | for market in market_names: 33 | ob = api.order_depth(market=market) 34 | print(market, ob["result"]) 35 | ``` 36 | 37 | More usage code examples you can find in [examples](https://github.com/testnet-exchange/python-viabtc-api/blob/master/examples) folder. Read the code first, it may contain some hardcoded constants that should be changed. 38 | 39 | --- 40 | 41 | # Working with the exchange server 42 | 43 | Since [I](https://github.com/ohld) have had a lot of troubles with the original exchange server by ViaBTC, I've decided to write this tutorial for beginners. I hope that helps. 44 | 45 | ## Install exchange 46 | 47 | For me the easiest way to install the exchange was found in [bitlum](https://github.com/bitlum)'s fork of the original [ViaBTC](https://github.com/viabtc/viabtc_exchange_server) repository. You need `docker` and `docker-compose` (up-to-date) to launch this installation script. 48 | 49 | ``` bash 50 | git clone https://github.com/testnet-exchange/viabtc_exchange_server 51 | cd viabtc_exchange_server/docker 52 | sudo docker-compose up 53 | ``` 54 | 55 | That's it! It successfully run on Ubuntu and Debian servers, but failed on macOS (there were some disk path errors that I balieve can be easily fixed if you are familiar with docker or stackoverflow). 56 | 57 | ## Connect to exchange local network 58 | 59 | `Docker-compose` creates the local net for all dockers images. Take a look at [docker-compose file](https://github.com/bitlum/viabtc_exchange_server/blob/master/docker/docker-compose.yml): you may notice the local ip addresses near every docker container. We will use the address of `accesshttp` container to make API requests. 60 | 61 | As all of that stuff is happening on the remote server's local network, we need to make some port forwarding from it to out development machine (in my case this is my macbook laptop): 62 | 63 | ``` bash 64 | ssh user@ -L 8080:192.168.18.45:8080 -N -f 65 | ``` 66 | 67 | where `192.168.18.45` is the ip address of `accesshttp` container and `8080` is its port. 68 | 69 | And now you can send API requests to `exchange_url = "http://localhost:8080"` 70 | 71 | ---- 72 | 73 | I spent a few hours to figure out how to run the exchange and make requests to it. If this tutorial helped you, smash the star button at the top of the page. And fell free to make Pull Requests with some additional functionallity. 74 | 75 | *Happy Coding!* 76 | 77 | [](https://morejust.foundation/?from=python-viabtc-api) 78 | -------------------------------------------------------------------------------- /ViaBTCAPI/ViaBTCAPI.py: -------------------------------------------------------------------------------- 1 | # author: okhlopkov.com 2 | # please consider using python3 3 | 4 | import random 5 | import requests 6 | 7 | class ViaBTCAPI(object): 8 | headers = {'content-type': 'application/json'} 9 | base_params = {"jsonrpc": "2.0", "id": 0} 10 | 11 | SELL_STR = "SELL" 12 | BUY_STR = "BUY" 13 | 14 | def __init__(self, exchange_url, _use_first_random_op_id=True): 15 | self.exchange_url = exchange_url 16 | 17 | # operation id should be unique for each operation 18 | self._op_id = 0 19 | if _use_first_random_op_id: 20 | self._op_id = random.randint(0, 1000000) 21 | 22 | 23 | def _execute(self, method, params): 24 | return requests.post( 25 | self.exchange_url, 26 | json={ 27 | "method": method, 28 | "params": params, 29 | **self.base_params}, 30 | headers=self.headers 31 | ).json() 32 | 33 | def _get_side_code(self, side): 34 | _side = 1 if side == self.SELL_STR else 2 if side == self.BUY_STR else 0 35 | if _side == 0: 36 | raise Exception("Only 'side={}' and 'side={}' allowed.".format(self.SELL_STR, self.BUY_STR)) 37 | return _side 38 | 39 | def balance_query(self, user_id=1, asset=None): 40 | if asset is None: 41 | return self._execute("balance.query", [user_id]) 42 | return self._execute("balance.query", [user_id, asset]) 43 | 44 | def balance_history( 45 | self, 46 | user_id=1, 47 | asset="BTC", 48 | business_type="", 49 | start_time=0, 50 | end_time=0, 51 | offset=0, 52 | limit=10 53 | ): 54 | return self._execute( 55 | "balance.history", 56 | [user_id, asset, "", start_time, end_time, offset, limit] 57 | ) 58 | 59 | def balance_update(self, user_id=1, asset="BTC", amount=1.1, business_type="", detail={}): 60 | self._op_id += 1 61 | return self._execute( 62 | "balance.update", 63 | [user_id, asset, business_type, self._op_id, str(amount), detail] 64 | ) 65 | 66 | def asset_list(self): 67 | return self._execute("asset.list", []) 68 | 69 | def asset_summary(self): 70 | return self._execute("asset.summary", []) 71 | 72 | def order_put_limit( 73 | self, 74 | user_id=1, 75 | market="BTCETH", 76 | side="SELL", 77 | amount=100, 78 | price=1, 79 | taker_fee_rate=0.0001, 80 | maker_fee_rate=0.0001, 81 | source="" 82 | ): 83 | _side = self._get_side_code(side) 84 | return self._execute( 85 | "order.put_limit", 86 | [user_id, market, _side, str(amount), str(price), 87 | str(taker_fee_rate), str(maker_fee_rate), source] 88 | ) 89 | 90 | def order_put_market(self): 91 | raise Exception("Not Implemented") 92 | 93 | def order_cancel(self, user_id, market, order_id): 94 | return self._execute("order.cancel", [user_id, market, order_id]) 95 | 96 | def order_deals(self, order_id=1, offset=0, limit=10): 97 | return self._execute("order.deals", [order_id, offset, limit]) 98 | 99 | def order_book(self, market="BTCETH", limit=10, side="SELL"): 100 | raise Exception("Official docs are wrong.
