What is this?

This unofficial Python API provides access to the conversational capabilities of Anthropic's Claude AI through a simple chat messaging interface.

While not officially supported by Anthropic, this library can enable interesting conversational applications.

It allows for:

  • Creating chat sessions with Claude and getting chat IDs.
  • Sending messages to Claude containing up to 5 attachment files (txt, pdf, csv, etc...) 10 MB each.
  • Retrieving chat message history.
  • Deleting old chats when they are no longer needed.

Some of the key things you can do with Claude through this API

  • Ask questions about a wide variety of topics. Claude can chat about current events, pop culture, sports, and more.

  • Get helpful explanations on complex topics. Ask Claude to explain concepts and ideas in simple terms.

  • Generate summaries from long text or documents. Just give the filepath as an attachment to Claude and get back a concise summary.

  • Receive thoughtful responses to open-ended prompts and ideas. Claude can brainstorm ideas, expand on concepts, and have philosophical discussions.

How to install

pip install unofficial-claude2-api

Uninstallation

pip uninstall unofficial-claude2-api

Requirements

These requirements are needed to auto retrieve session cookie and UserAgent using selenium

  • Firefox installed, and with at least one profile logged into Claude.
  • geckodriver installed inside a folder registered in PATH environment variable.

( scrolling through this README you'll find also a manual alternative )

Example Usage

from claude2_api.client import (
    ClaudeAPIClient,
    SendMessageResponse,
    MessageRateLimitError,
)
from claude2_api.session import SessionData, get_session_data

# Wildcard import will also work the same as above
# from claude2_api import *

# List of attachments filepaths, up to 5, max 20 MB each
FILEPATH_LIST = [
    "test1.txt",
    "test2.txt",
]

# This function will automatically retrieve a SessionData instance using selenium
# It will auto gather cookie session, user agent and organization ID.
# Omitting profile argument will use default Firefox profile
session: SessionData = get_session_data()

# Initialize a client instance using a session
# Optionally change the requests timeout parameter to best fit your needs...default to 240 seconds.
client = ClaudeAPIClient(session, timeout=240)

# Create a new chat and cache the chat_id
chat_id = client.create_chat()
if not chat_id:
    # This will not throw MessageRateLimitError
    # But it still means that account has no more messages left.
    print("\nMessage limit hit, cannot create chat...")
    quit()

try:
    # Used for sending message with or without attachments
    # Returns a SendMessageResponse instance
    res: SendMessageResponse = client.send_message(
        chat_id, "Hello!", attachment_paths=FILEPATH_LIST
    )
    # Inspect answer
    if res.answer:
        print(res.answer)
    else:
        # Inspect response status code and error string
        print(f"\nError code {res.status_code}, response -> {res.error_response}")
except MessageRateLimitError as e:
    # The exception will hold these informations about the rate limit:
    print(f"\nMessage limit hit, resets at {e.reset_date}")
    print(f"\n{e.sleep_sec} seconds left until -> {e.reset_timestamp}")
    quit()
finally:
    # Perform chat deletion for cleanup
    client.delete_chat(chat_id)

# Get a list of all chats ids
all_chat_ids = client.get_all_chat_ids()
# Delete all chats
for chat in all_chat_ids:
    client.delete_chat(chat)

# Or by using a shortcut utility
client.delete_all_chats()

Tips

How to access specific chat data ( retrieving chat conversations )

# A convenience method to access a specific chat conversation is
chat_data = client.get_chat_data(chat_id)

chat_data will be the same json dictionary returned by calling /api/organizations/{organization_id}/chat_conversations/{chat_id}

Here's an example of this json:

{
    "uuid": "<ConversationUUID>",
    "name": "",
    "summary": "",
    "model": null,
    "created_at": "1997-12-25T13:33:33.959409+00:00",
    "updated_at": "1997-12-25T13:33:39.487561+00:00",
    "chat_messages": [
        {
            "uuid": "<MessageUUID>",
            "text": "Who is Bugs Bunny?",
            "sender": "human",
            "index": 0,
            "created_at": "1997-12-25T13:33:39.487561+00:00",
            "updated_at": "1997-12-25T13:33:40.959409+00:00",
            "edited_at": null,
            "chat_feedback": null,
            "attachments": []
        },
        {
            "uuid": "<MessageUUID>",
            "text": "<Claude response's text>",
            "sender": "assistant",
            "index": 1,
            "created_at": "1997-12-25T13:33:40.959409+00:00",
            "updated_at": "1997-12-25T13:33:42.487561+00:00",
            "edited_at": null,
            "chat_feedback": null,
            "attachments": []
        }
    ]
}

How to avoid using selenium ( faster loading )

If for whatever reason you'd like to avoid auto session gathering using selenium, you just need to manually create a SessionData class for ClaudeAPIClient constructor, like so...

from claude2_api.session import SessionData

cookie_header_value = "The entire Cookie header value string when you visit https://claude.ai/chats"
user_agent = "User agent to use, required"

# You can retrieve this string from /api/organizations endpoint
# If omitted or None it will be auto retrieved when instantiating ClaudeAPIClient
organization_id = "<org_uuid>"

session = SessionData(cookie_header_value, user_agent, organization_id)

How to set HTTP/S proxy

NOTE ( Only proxies with no user/passwd authentication are supported )

If you'd like to set a proxy for all requests, follow this example:

from claude2_api.client import HTTPProxy, ClaudeAPIClient
from claude2_api.session import SessionData

# Create HTTPProxy instance
http_proxy = HTTPProxy(
    "the.proxy.ip.addr",    # Proxy IP
    8080,                   # Proxy port
    use_ssl=False           # Set to True if proxy uses HTTPS schema
)

session = SessionData(...)

# Give the proxy instance to ClaudeAPIClient constructor, along with session data.
client = ClaudeAPIClient(session, proxy=http_proxy)

Changing Claude model

In case you have accounts that are unable to migrate to newer models, you can override the model_name string parameter of ClaudeAPIClient constructor.

from claude2_api.client import ClaudeAPIClient
from claude2_api.session import SessionData

session = SessionData(...)

# Defaults to claude-2.1
client = ClaudeAPIClient(session, model_name="claude-2.0")

TROUBLESHOOTING

*This bug should be already fixed after version 0.2.2*

This api will sometime return a 403 status_code when calling send_message, when this happens it is recommeded to look for these things:

  • Check if your IP location is allowed, should be in US/UK, other locations may work sporadically.

  • Don't try to send the same prompt/file over and over again, instead wait for some time, and change input.
