A Cleverbot API wrapper for Python with asynchronous functionality. is a Cleverbot API wrapper for Python made to be both fully-featured and easy to use.


import cleverbot

cb = cleverbot.Cleverbot('YOUR_API_KEY', timeout=60)

text = input("Say to Cleverbot: ")
    reply = cb.say(text)
except cleverbot.CleverbotError as error:


Install it normally from PyPI with pip:

pip install

Or install it with the asynchronous dependencies (Python 3.4.2+ only):

pip install[async]



  • requests 1.0.0+
  • Asynchronous:
    • aiohttp 1.0.0+


First import the package:

import cleverbot

Then initialize Cleverbot with your API key and optionally a cleverbot state and or timeout:

cb = cleverbot.Cleverbot('YOUR_API_KEY', cs='76nxdxIJ02AAA', timeout=60)

The cleverbot state is the encoded state of the conversation that you get from talking to Cleverbot and includes the whole conversation history.

If you have the asynchronous dependencies and want to use Cleverbot asynchronously import cleverbot.async_ and initialize Cleverbot from cleverbot.async_.Cleverbot instead. The only differences are that say is a coroutine and that you can pass an event loop to Cleverbot with a loop keyword argument.

You can now start talking to Cleverbot.

Get the reply from the request:

reply = cb.say("Hello")

Or alternatively get it later:

reply = cb.output

You can also pass in keyword arguments such as cs to change the conversation, vtext to change the current conversation’s history, or even cb_settings_tweak to change Cleverbot’s mood. Read the “Parameters” section of the official Cleverbot API docs for more information.

If something goes wrong with the request, such as an invalid API key, an APIError will be raised containing the error message or, if you’ve defined a timeout and you don’t get a reply within the defined amount of seconds you’ll get a Timeout.

As an example:

cleverbot.errors.APIError: Missing or invalid API key or POST request, please visit

You can get the error message and additionally the HTTP status from the error like so:

except cleverbot.APIError as error:
    print(error.error, error.status)

This is similar for Timeout where you can get the defined timeout value with error.timeout.

Additionally, all Cleverbot errors subclass CleverbotError so you can use it to catch every Cleverbot related error.

To access the data gained from the conversations you can either get them from an attribute as shown previously or directly get them from

cb.conversation_id ==['conversation_id']

Note that every attribute except for cs (i.e., the cleverbot state) is read-only and will get shadowed if you set it to something.

For a list of all of the data and their descriptions go to the “JSON Reply” section in the official Cleverbot API docs.

To reset the data you can simply do the following:


When you’re done with the current instance of Cleverbot, close Cleverbot’s connection to the API:
