Getting Started

1. Get Your API Key

IMPORTANT: Before you can use ChatRoutes, you must obtain an API key:

1. Visit chatroutes.com
2. Sign up for a free account
3. Go to Dashboard → Navigate to the API section
4. Generate your API key
5. Copy and save your API key securely

2. Quick Start

from chatroutes import ChatRoutes

client = ChatRoutes(api_key="your-api-key")

conversation = client.conversations.create({
    'title': 'My First Conversation',
    'model': 'gpt-5'  # or 'claude-opus-4-1', 'claude-sonnet-4-5', etc.
})

response = client.messages.send(
    conversation['id'],
    {
        'content': 'Hello, how are you?',
        'model': 'gpt-5'
    }
)

print(response['message']['content'])

Supported Models

ChatRoutes currently supports the following AI models:

OpenAI:

• gpt-5 (default) - OpenAI's GPT-5

Anthropic Claude 4:

• claude-opus-4-1 - Claude Opus 4.1 (most capable)
• claude-opus-4 - Claude Opus 4
• claude-opus-4-0 - Claude Opus 4.0
• claude-sonnet-4-5 - Claude Sonnet 4.5 (best for coding)
• claude-sonnet-4-0 - Claude Sonnet 4.0

Anthropic Claude 3:

• claude-3-7-sonnet-latest - Claude 3.7 Sonnet (latest)
• claude-3-5-haiku-latest - Claude 3.5 Haiku (fastest)

Important: Use these exact model names. Other model names (e.g., gpt-4o, gpt-4o-mini, claude-sonnet-4) are not supported and will result in an error.

Features

• Conversation Management: Create, list, update, and delete conversations
• Message Handling: Send messages with support for streaming responses
• Branch Operations: Create and manage conversation branches for exploring alternatives
• Checkpoint Management: Save and restore conversation context at specific points
• Type Safety: Full type hints using TypedDict for better IDE support
• Error Handling: Comprehensive exception hierarchy for different error scenarios
• Retry Logic: Built-in exponential backoff retry mechanism

Usage Examples

Creating a Conversation

conversation = client.conversations.create({
    'title': 'Product Discussion',
    'model': 'gpt-5'
})

Sending Messages

response = client.messages.send(
    conversation_id='conv_123',
    data={
        'content': 'What are the key features?',
        'model': 'gpt-5',
        'temperature': 0.7
    }
)

print(response['message']['content'])  # AI response
print(f"Tokens used: {response['usage']['totalTokens']}")

Streaming Responses

def on_chunk(chunk):
    if chunk.get('type') == 'content' and chunk.get('content'):
        print(chunk['content'], end='', flush=True)

def on_complete(message):
    print(f"\n\nMessage ID: {message['id']}")

client.messages.stream(
    conversation_id='conv_123',
    data={'content': 'Tell me a story'},
    on_chunk=on_chunk,
    on_complete=on_complete
)

Working with Branches

branch = client.branches.create(
    conversation_id='conv_123',
    data={
        'title': 'Alternative Response',
        'contextMode': 'FULL'
    }
)

fork = client.branches.fork(
    conversation_id='conv_123',
    data={
        'forkPointMessageId': 'msg_456',
        'title': 'Exploring Different Approach'
    }
)

Listing Conversations

result = client.conversations.list({
    'page': 1,
    'limit': 10,
    'filter': 'all'
})

for conv in result['data']:
    print(f"{conv['title']} - {conv['createdAt']}")

Managing Checkpoints

Checkpoints allow you to save conversation context at specific points and manage long conversations efficiently:

branches = client.branches.list(conversation_id='conv_123')
main_branch = next(b for b in branches if b['isMain'])

checkpoint = client.checkpoints.create(
    conversation_id='conv_123',
    branch_id=main_branch['id'],
    anchor_message_id='msg_456'
)

print(f"Checkpoint created: {checkpoint['id']}")
print(f"Summary: {checkpoint['summary']}")
print(f"Token count: {checkpoint['token_count']}")

checkpoints = client.checkpoints.list('conv_123')
for cp in checkpoints:
    print(f"{cp['id']}: {cp['summary']}")

response = client.messages.send(
    conversation_id='conv_123',
    data={'content': 'Continue the conversation'}
)

metadata = response['message'].get('metadata', {})
if metadata.get('checkpoint_used'):
    print(f"Checkpoint was used for this response")
    print(f"Context messages: {metadata.get('context_message_count')}")

Error Handling

The SDK provides specific exception types for different error scenarios:

from chatroutes import (
    ChatRoutesError,
    AuthenticationError,
    RateLimitError,
    ValidationError,
    NotFoundError,
    ServerError
)

try:
    conversation = client.conversations.get('conv_123')
except AuthenticationError:
    print("Invalid API key")
except NotFoundError:
    print("Conversation not found")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after} seconds")
except ChatRoutesError as e:
    print(f"Error: {e.message}")
