# Zymemory Python SDK

**Official Python client for the Zymemory API** - Long-term memory for AI applications.

Zymemory provides a powerful memory system for AI assistants, chatbots, and agents, enabling them to remember and recall information across conversations.

[![PyPI version](https://badge.fury.io/py/zymemory.svg)](https://pypi.org/project/zymemory/)
[![Python 3.8+](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

## Features

- **Semantic Memory Search** - Find relevant memories using natural language
- **Memory Linking** - Connect related memories for graph-based recall
- **Conversation Storage** - Automatically cluster conversations into structured memories
- **Smart Clustering** - AI-powered organization of information
- **Multi-tenant** - Secure isolation for different users and organizations
- **Fast & Scalable** - Built on high-performance infrastructure

## Installation

```bash
pip install zymemory
```

## Quick Start

```python
from zymemory import ZymemoryClient

# Initialize client
client = ZymemoryClient(
    api_key="your-org-api-key",
    org_email="your-org@example.com",
    user_token="user-specific-token"
)

# Search for memories
results = client.search("What are my coffee preferences?")
for memory in results.memories:
    print(f"{memory.content}")
    print(f"   Keywords: {', '.join(memory.keywords)}")

# Create a new memory
memory = client.create_memory("I prefer oat milk lattes in the morning")
print(f"Created memory #{memory.id}")

# Store a conversation
client.store_conversation(
    user_input="What's the weather today?",
    assistant_output="It's sunny and 72°F!"
)
```

## Authentication

Zymemory uses a two-tier authentication system:

1. **Organization API Key** - Identifies your organization
2. **User Token** - Identifies the end user

### Getting Started

1. **Get your organization API key** from the Zymemory dashboard
2. **Register your end users:**

```python
# First, initialize with just org credentials
client = ZymemoryClient(
    api_key="your-org-key",
    org_email="your-org@example.com"
)

# Register a new end user
user = client.register_user(
    external_id="user_123",  # Your system's user ID
    name="John Doe",
    email="john@example.com"
)

# Save the user token for future requests
print(f"User token: {user.token}")

# Now use it for all memory operations
client.user_token = user.token
```

## Usage Examples

### Memory Management

```python
from zymemory import ZymemoryClient

client = ZymemoryClient(
    api_key="your-key",
    org_email="org@example.com",
    user_token="user-token"
)

# Create memories
memory1 = client.create_memory("I love dark roast coffee")
memory2 = client.create_memory("My favorite cafe is Blue Bottle", auto_merge=True)

# List all memories with pagination
result = client.list_memories(page=1, page_size=20)
print(f"Total memories: {result.total}")
for memory in result.memories:
    print(f"  {memory.id}: {memory.content}")

# Delete a memory
client.delete_memory(memory1.id)
```

### Searching Memories

```python
# Simple search
results = client.search("coffee preferences", top_k=5)

# Process results
print(f"Found {len(results.memories)} memories:")
for memory in results.memories:
    print(f"  {memory.content}")
    print(f"     Keywords: {memory.keywords}")
    print(f"     Connections: {memory.link_count}")

# Get just the memories (exclude unassigned conversations)
memories = client.search_memories_only("favorite foods", top_k=10)
```

### Memory Linking

```python
# Create links between related memories
client.create_link(source_id=1, destination_id=2)

# Get connected memories
links = client.get_memory_radius(memory_id=1, depth=2)
print(f"Outgoing links: {len(links['outgoing'])}")
print(f"Incoming links: {len(links['incoming'])}")

# Explore the memory graph
for link in links['outgoing']:
    dest = link['destination']
    print(f"  → {dest['content']}")
```

### Conversation Storage

```python
# Store conversation turns
# The backend automatically processes these into structured memories
client.store_conversation(
    user_input="I want to learn Python",
    assistant_output="Great! Python is perfect for beginners..."
)

client.store_conversation(
    user_input="What's a good first project?",
    assistant_output="Try building a to-do list app..."
)

# Later, search across conversations
results = client.search("learning programming")
# The system will have clustered related conversations into memories
```

### Building a Chatbot with Memory

```python
from zymemory import ZymemoryClient
from anthropic import Anthropic  # or openai, etc.

class MemoryChatbot:
    def __init__(self, zymemory_client, llm_client):
        self.memory = zymemory_client
        self.llm = llm_client

    def chat(self, user_message):
        # 1. Search for relevant memories
        context = self.memory.search(user_message, top_k=5)

        # 2. Build prompt with memory context
        memory_context = "\\n".join([
            f"- {m.content}" for m in context.memories[:3]
        ])

        system_prompt = f"""You are a helpful assistant with long-term memory.

Here's what you remember:
{memory_context}

Use this information to provide personalized responses."""

        # 3. Get LLM response
        response = self.llm.messages.create(
            model="claude-3-haiku-20240307",
            system=system_prompt,
            messages=[{"role": "user", "content": user_message}]
        )

        assistant_message = response.content[0].text

        # 4. Store conversation for future recall
        self.memory.store_conversation(user_message, assistant_message)

        return assistant_message

# Use it
memory_client = ZymemoryClient(api_key="...", org_email="...", user_token="...")
llm = Anthropic(api_key="...")
bot = MemoryChatbot(memory_client, llm)

print(bot.chat("What did I say about coffee?"))
```

### Bulk Operations

```python
# Get all memories (useful for export)
all_memories = client.get_all_memories(max_pages=10)
print(f"Total: {len(all_memories)} memories")

# Export to JSON
import json
with open("memories_backup.json", "w") as f:
    json.dump([{
        "id": m.id,
        "content": m.content,
        "keywords": m.keywords
    } for m in all_memories], f, indent=2)
```
