unofficial-claude2-api 0.1.7

Unofficial Claude2 API supporting direct HTTP chat creation/deletion/retrieval, multiple message attachments and auto session gathering using Firefox with geckodriver.

unofficial-claude2-api

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...) 20 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

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 safely, same as above
# from claude2_api import *

# List of attachments filepaths, up to 5, max 10 MB each
FILEPATH_LIST = [
    "test1.txt",
    "test2.txt",
]

# This function will automatically retrieve a SessionData instance using selenium
# Omitting profile argument will use default Firefox profile
data: SessionData = get_session_data()

# Initialize a client instance using a session
client = ClaudeAPIClient(data)

# Create a new chat and cache the chat_id
chat_id = client.create_chat()
if not chat_id:
    # This will not throw MessageRateLimitHit
    # But it still means that account has no more messages left.
    print(f"\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, timeout=240
    )
    # Inspect answer
    if res.answer:
        print(res.answer)
    else:
        # Inspect response status code and json error
        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.resetDate}")
    print(f"\n{e.sleep_sec} seconds left until -> {e.resetTimestamp}")
    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()

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"

data = SessionData(cookie_header_value, user_agent)

TROUBLESHOOTING

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.
