Coinigy API v2 Signature and Request Example in Python 3

sample.py

import time
import hmac
import hashlib
import requests

BASE_URL = 'https://api.coinigy.com'
ENDPOINT = '/api/v2/private/exchanges'
X_API_KEY = 'your_api_v2_key_goes_here'
SECRET = 'your_corresponding_api_v2_secret_goes_here'
METHOD = 'GET'
UNIXTIME = time.time()
PARAMS = {} # = {'StartDate':'2018-07-30T00:00:00.000Z','EndDate':'2018-07-30T23:59:59.000Z'}
BODY = ''

X_API_TIMESTAMP = str(int(UNIXTIME))
query_string = "?" + "&".join( [ key + '=' + urllib.parse.quote_plus(PARAMS[key]) for key in PARAMS.keys() ] )
msg = X_API_KEY + X_API_TIMESTAMP + METHOD + ENDPOINT + (query_string if len(query_string) > 1 else '') + BODY
signature_bytes = hmac.new(SECRET.encode("ascii"), msg.encode("ascii"), digestmod=hashlib.sha256).digest()
signature_hex = map("{:02X}".format, signature_bytes)
X_API_SIGN = ''.join(signature_hex)

headers = {'Accept': 'application/json', 'Content-Type': 'application/json', 'X-API-SIGN': X_API_SIGN, 'X-API-TIMESTAMP' : X_API_TIMESTAMP, 'X-API-KEY': X_API_KEY}
r = requests.get(BASE_URL + ENDPOINT, headers=headers, params=PARAMS, data=BODY)

print(r.status_code, r.reason, r.content, BASE_URL + ENDPOINT)

'X-API-KEY': KEY

should be

'X-API-KEY': X_API_KEY

Recent update: The endpoint will need to include the properly encoded query parameters going forward. This code doesn't include that at the moment

I'm not sure what this means. Can you please clarify what are the 'properly encoded query parameters' or update the documentation? I'm just getting the same 401 Unauthorized b'' error using v2 creds.

I tested using your parameters from Stackoverflow and I'm not getting the same signature you posted there: F9D2192675BA4D7BDB6D768DF077CEEF2A3FB72481B54E37E93CF750EF59892B

Thanks

The signature I had on stackoverflow was wrong. I forgot to update it the last time I made an edit to that answer. I've now updated it to be correct.

Also here is an example of python3 code generating the correct signature. I will update the code on this gist as well:

import time
import hmac
import hashlib
import requests
import urllib.parse
from datetime import datetime, timezone

BASE_URL = 'https://api.coinigy.com'
ENDPOINT = '/api/v2/private/exchanges'
X_API_KEY = 'keykeykeykeykeykeykeykeykeykeyke'
SECRET = 'secretsecretsecretsecretsecretse'
METHOD = 'GET'
UNIXTIME = datetime.fromtimestamp(1532718830, timezone.utc)
PARAMS = {'pythagoreanTheorem':'a^2+b^2=c^2'}
BODY = ''

X_API_TIMESTAMP = str(int(datetime.timestamp(UNIXTIME)))
query_string = "?" + "&".join( [ key + '=' + urllib.parse.quote_plus(PARAMS[key]) for key in PARAMS.keys() ] )
msg = X_API_KEY + X_API_TIMESTAMP + METHOD + ENDPOINT + (query_string if len(query_string) > 1 else '') + BODY
signature_bytes = hmac.new(SECRET.encode("ascii"), msg.encode("ascii"), digestmod=hashlib.sha256).digest()
signature_hex = map("{:02X}".format, signature_bytes)
X_API_SIGN = ''.join(signature_hex)

print(X_API_SIGN)

#headers = {'Accept': 'application/json', 'Content-Type': 'application/json', 'X-API-SIGN': X_API_SIGN, 'X-API-TIMESTAMP' : X_API_TIMESTAMP, 'X-API-KEY': X_API_KEY}
#r = requests.get(BASE_URL + ENDPOINT, headers=headers, params=PARAMS, data=BODY)

#print(r.status_code, r.reason, r.content, BASE_URL + ENDPOINT)

Here is a working example. Just put in your key and secret and it should return hourly candles between the two dates as well as other request info:

import time
import hmac
import hashlib
import requests
import urllib.parse
from datetime import datetime, timezone

BASE_URL = 'https://api.coinigy.com'
ENDPOINT = '/api/v2/private/exchanges/BINA/markets/BTC/USDT/ohlc/h'
X_API_KEY = 'keykeykey'
SECRET = 'secretsecretsecret'
METHOD = 'GET'
UNIXTIME = datetime.fromtimestamp(time.time(), timezone.utc)
PARAMS = {'StartDate':'2019-01-01T00:00:00.000Z', 'EndDate':'2019-01-02T00:00:00.000Z'}
BODY = ''

X_API_TIMESTAMP = str(int(datetime.timestamp(UNIXTIME)))
query_string = "?" + "&".join( [ key + '=' + urllib.parse.quote_plus(PARAMS[key]) for key in PARAMS.keys() ] )
msg = X_API_KEY + X_API_TIMESTAMP + METHOD + ENDPOINT + (query_string if len(query_string) > 1 else '') + BODY
signature_bytes = hmac.new(SECRET.encode("ascii"), msg.encode("ascii"), digestmod=hashlib.sha256).digest()
signature_hex = map("{:02X}".format, signature_bytes)
X_API_SIGN = ''.join(signature_hex)

print(X_API_SIGN)

headers = {'Accept': 'application/json', 'Content-Type': 'application/json', 'X-API-SIGN': X_API_SIGN, 'X-API-TIMESTAMP' : X_API_TIMESTAMP, 'X-API-KEY': X_API_KEY}
r = requests.get(BASE_URL + ENDPOINT, headers=headers, params=PARAMS, data=BODY)
print(r.status_code, r.reason, r.content, BASE_URL + ENDPOINT)

Hi Phillip I'm still getting the same 401 error. I replaced the API and SECRET keys and it doesn't work. Any ideas what might cause this issue? Thanks

Any ideas what might cause this issue?

There are a few reasons:

• The clock on your computer may be out of sync. The request needs to occur within 30sec of Coinigy server time otherwise it is denied
• Make sure you're using a v2 api key, not a v1 key
• Make sure you have a Crypto Feed subscription

That's about it

Thanks Joe. I checked and points 2 and 3 are definitely correct. I also made sure my time is current and I double-checked against unixtimestamp .com and my output definitely matches the universal time. Still no luck. Any other things I could try on my end?

I'm out of ideas. If you want to contact me through the Coinigy support email and ask for me, I can continue helping you there. Next thing I would try is looking into your account to make sure everything is set up properly.
