How to get market with python 3?

    access_key = 'xxxx'
    secret_key = 'yyyy'
    ctx = ssl.create_default_context()
    ctx.check_hostname = False
    ctx.verify_mode = ssl.CERT_NONE
    epoch_time = str(int(time.time())) + '000'
    request = 'access_key=' + access_key + '&tonce=' + epoch_time
    message = 'GET|/api/v2/markets|' + request
    signature = hmac.new(b'secret_key',b'message',hashlib.sha256).hexdigest()
    query = 'https://graviex.net/api/v2/markets?' + request + '&signature=' + signature
    graviex = urllib.request.urlopen(query, context=ctx).read()
    print(graviex)

Not work:
401. Unauthorized


hello mazertwo, I solve this problem!

{"error":{"code":2007,"message":"The tonce 1527560783000 is invalid, current timestamp is 1527560317000."}}

you need to leave your tonce (timestamp your PC converted to UTC) exactly the same as the timestamp UTC graviex


#Python 3.6

import hashlib
import hmac
import requests
import time
import ssl
import json

access_key = 'api key here '
secret_key = 'secret key here'


# 0. making ssl context - verify should be turned off
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

# ------------------
# Get markets list
# ------------------

# 1. list markets

epoch_time = str(int(time.time()+30))+'000'
print(epoch_time)
request = 'access_key=' + access_key + '&tonce=' + epoch_time
message = 'GET|/api/v2/markets|' + request

secret_key_bytes= bytes(secret_key , 'latin-1')
message_bytes = bytes(message, 'latin-1')

# 1.1 generate the hash.
signature = hmac.new(
    secret_key_bytes,
    message_bytes,
    hashlib.sha256
).hexdigest()

# 1.2 list markets
query = 'https://graviex.net/api/v2/markets?' + (request) + '&signature=' + (signature)


print(query) #put in the browser



r = requests.get(query)
data = json.loads(r.content.decode('utf-8'))
print(data)


#---------------------------------------------------------------------



#I had to increase 30 units in the timestamp to work here in my region. You should get the value of "query" and put in the browser subitrair #the timestamp value of graviex server by its timestamp.

#I spent many hours to solve this problem.

As soon as I've posted this, the attacker stopped his pool .. now we need to rollback the last 13h of the chain or leave the attacker with 13h * 1 second blocks

Hi JMAN,
I don't know whether you succeeded, but I have a working sample for Kraken, BTC-e and Poloniex in this project: https://github.com/krijnsent/crypto_vba
Getting a Bittrex account and getting that in that project too is on my ToDo list.
Cheers,
Koen
