apipool 0.0.2

Multiple API Key Manager

Welcome to apipool Documentation

apipool allows developer manipulate multi api key at same time. For example, if single api key has 1k/day quota, then you can register 10 api keys, and let apipool to automatically rotate the key.

Features:

• automatically rotate apikey.
• built-in usage statistics, easy to search by time, status, apikey. You can deploy stats collector on any cloud relational database.
• clean api, minimal code is required to implement complex feature.

Example:

there’s a google geocoding example at: https://github.com/MacHu-GWU/apipool-project/blob/master/examples/google_geocoding.py

Tutorial

Let’s walk through with a twitter api example, the api client we use is python-twitter: https://github.com/bear/python-twitter.

The python-twitter usage:

import twitter

# create api client
api = twitter.Api(
    consumer_key="consumer_key"z,
    consumer_secret="consumer_secret",
    access_token_key="access_token",
    access_token_secret="access_token_secret",
)

# make api call
statuses = api.GetUserTimeline(screen_name="trump")

The apipool usage:

import twitter
from apipool import ApiKey, ApiKeyManager

class TwitterApiKey(ApiKey):
    def __init__(self,
                 consumer_key,
                 consumer_secret,
                 access_token_key,
                 access_token_secret)
        self.consumer_key = consumer_key
        self.consumer_secret = consumer_secret
        self.access_token_key = access_token_key
        self.access_token_secret = access_token_secret

    def user_01_get_primary_key(self):
        return self.access_token_key

    def user_02_create_client(self):
        return twitter.Api(
            consumer_key=self.consumer_key,
            consumer_secret=self.consumer_secret,
            access_token_key=self.access_token_key,
            access_token_secret=self.access_token_secret,
        )

    def user_03_test_usable(self, client):
        statuses = client.GetUserTimeline(screen_name="trump")
        if len(statuses) >= 5:
            return True
        else:
            return False

apikey_data_list = [
    {
        "consumer_key": xxx,
        "consumer_secret": xxx,
        "access_token_key": xxx,
        "access_token_secret": xxx,
    },
    {...},
    {...},
]

apikey_list = [
    TwitterApiKey(**apikey_data)
    for apikey_data in apikey_data_list
]

manager = ApiKeyManager(apikey_list=apikey_list)

DummyClient:

now we can use the manager.dummyclient object like how we use the twitter.Api() object. However, the apikey is automatically rotated, and usage events are also automatically recorded.

manager.check_usable()

# the api key is automatically rotated under the hood
statuses = manager.dummyclient.GetUserTimeline(screen_name="trump")

for _ in range(10):
    manager.dummyclient.GetUserTimeline(screen_name="trump")

StatsCollector:

now we can use manager.stats object to access usage stats, and also query usage events.

>>> manager.stats.usage_count_stats_in_recent_n_seconds()
{"xxx access_token_key": 3, "xxx access_token_key": 4, "xxx access_token_key": 3}

>>> from apipool import StatusCollection
>>> events_list = list(manager.stats.query_event_in_recent_n_seconds(
    n_seconds=24*3600,
    status_id=StatusCollection.c1_Success.id,
))
>>> events_list
[
    Event(apikey_id=xxx, finished_at=datetime(xxx), status_id=xxx),
    Event(...),
    ...
]
