wzlight

wzlight is an asynchronous Python wrapper for the Call of Duty API that focuses on Warzone endpoints.

Features

• Asynchronous with help of HTTPX, the HTTP client library
• Light : only centered around the few GET methods to collect Warzone stats
• Handle SSO auth. the (now) only available way to connect to the API

Installation

  # with pip
  pip install wzlight

  # with Poetry
  poetry add wzlight

Client usage

import os
import asyncio
from pprint import pprint

import httpx
from dotenv import load_dotenv

from wzlight import Api


async def main():

    load_dotenv()
    sso = os.environ["SSO"]
    username = "amadevs#1689"
    platform = "battle"

    # Initialize Api with a SSO token
    # SSO token can be found in browser while login-in to callofduty.com

    api = Api(sso)

    # Wrapper internal methods are using the httpx async HTTP library

    # Initially httpx.AsyncClient) was built in its own cls, but letting users define it at app-level --as a context manager,
    # ensures more robustness and flexibility (custom timeout, limits...) and prevent async loop event errors.
    # Thus, your main() should follow the preferred approach while working with an async http client:

    async with httpx.AsyncClient() as httpxClient:

        profile = await api.GetProfile(httpxClient, platform, username)
        pprint(profile, depth=2)

        recent_matches = await api.GetRecentMatches(httpxClient, platform, username)
        recent_matches_short = [match for match in recent_matches[:2]]
        pprint(recent_matches_short, depth=3)

        matchStats = await api.GetMatch(
            httpxClient, platform, matchId=11378702801403672847
        )
        pprint(matchStats, depth=1)


if __name__ == "__main__":
    asyncio.run(main())

Focus : example of a concurrent run

import os
import asyncio
from pprint import pprint

import httpx
from dotenv import load_dotenv
from typing import AsyncContextManager

from wzlight import Api

async def main():

    load_dotenv()
    sso = os.environ["SSO"]
    username = "amadevs#1689"
    platform = "battle"

    # Initialize Api with a SSO token

    api = Api(sso)

    # We're running concurrently on match details endpoint, given a list of matchIds
    # COD API is unofficial and undocumented, rate limits / restrictions are not known
    # So you should probably --at least, handle some concurrency limits e.g for fetching a batch of matchs
    # See. httpx.Limits, async.Semaphore or other librairies such as aiometer


    matchIds = [
        5850171651963062771,
        6910618934945378397,
        16975576559940046894,
        639235311963231866,
        11887968911271282782,
        7897970481732864368,
    ]

    # enclose api.getMatch into safe_GetMatch that accept a Semaphore threshold arg.

    limit = asyncio.Semaphore(2)

    async def safe_GetMatch(httpxClient, platform, matchId, sema: AsyncContextManager):
        # No more than two concurrent tasks. If reaches two, wait 1 sec
        async with sema:
            r = await api.GetMatch(httpxClient, platform, matchId)
            if sema.locked():
                print("Concurrency limit reached, waiting ...")
                await asyncio.sleep(1)
            return r

    # Do not forget to open Client as context manager :
    async with httpx.AsyncClient() as httpxClient:
	
        sema = asyncio.Semaphore(2)
        
        tasks = []
        for matchId in matchIds:
            tasks.append(safe_GetMatch(httpxClient, platform, matchId, sema))
        results = await asyncio.gather(*tasks, return_exceptions=True)
        return resultss
            
    print(len(results))


if __name__ == "__main__":
    asyncio.run(main())

Inspiration (heavily) came from :
Also check those links if your need documentation on how the API works

• EthanC/CallofDuty.py : the most complete but now slightly deprecated (mainly the Auth.), async COD client (lot of exploited endpoints and methods + more than WZ)
• Lierrmm/Node-CallOfDuty : very clean async. wrapper written in NodeJS. Also check their Discord to get a grip on API subtleties and unofficial changes (privacy changes, rate limits etc)
• valtov/WarzoneStats : very clean synch. Python wrapper by the creator of wzstats.gg
