# Backboard Python SDK

A developer-friendly Python SDK for the Backboard API. Build conversational AI applications with persistent memory and intelligent document processing.

> New to Backboard? We include $10 in free credits to get you started and support 1,800+ LLMs across major providers.

## New in v1.4.3

- **Multiple Embedding Models**: Support for custom embedding providers and models (OpenAI, Google, Cohere, etc.)
- **Configurable Embedding Dimensions**: Set custom embedding dimensions for advanced use cases
- **Memory Support**: Add persistent memory to assistants with automatic context retrieval
- **Memory Modes**: Control memory behavior with Auto, Readonly, and off modes
- **Memory Statistics**: Track usage and limits

## Installation

```bash
pip install backboard-sdk
```


## Quick Start

```python
import asyncio
from backboard import BackboardClient

async def main():
    client = BackboardClient(api_key="your_api_key_here")

    assistant = await client.create_assistant(
        name="Support Bot",
        description="A helpful customer support assistant",
    )

    thread = await client.create_thread(assistant.assistant_id)

    response = await client.add_message(
        thread_id=thread.thread_id,
        content="Hello! Can you help me with my account?",
        llm_provider="openai",
        model_name="gpt-4o",
        stream=False,
    )

    print(response.latest_message.content)

    # Streaming
    async for event in await client.add_message(
        thread_id=thread.thread_id,
        content="Stream me a short response",
        stream=True,
    ):
        if event.get("type") == "content_streaming":
            print(event.get("content", ""), end="", flush=True)

if __name__ == "__main__":
    asyncio.run(main())
```

    if chunk.get('type') == 'content_streaming':
        print(chunk.get('content', ''), end='', flush=True)
```

### Tool Integration (Simplified in v1.3.3)

#### Tool Definitions
```python
# Use plain JSON objects (no verbose SDK classes needed!)
tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get current weather",
            "parameters": {
                "type": "object",
                "properties": {
                    "location": {"type": "string", "description": "City name"}
                },
                "required": ["location"]
            }
        }
    }
]

assistant = await client.create_assistant(
    name="Weather Assistant",
    tools=tools,
)
```

#### Tool Call Handling
```python
import json

# Enhanced object-oriented access with automatic JSON parsing
response = await client.add_message(
    thread_id=thread_id,
    content="What's the weather in San Francisco?",
    stream=False
)

if response.status == "REQUIRES_ACTION" and response.tool_calls:
    tool_outputs = []
    
    # Process each tool call
    for tc in response.tool_calls:
        if tc.function.name == "get_current_weather":
            # Get parsed arguments (required parameters are guaranteed by API)
            args = tc.function.parsed_arguments
            location = args["location"]
            
            # Execute your function and format the output
            weather_data = {
                "temperature": "68°F",
                "condition": "Sunny",
                "location": location
            }
            
            tool_outputs.append({
                "tool_call_id": tc.id,
                "output": json.dumps(weather_data)
            })
    
    # Submit the tool outputs back to continue the conversation
    final_response = await client.submit_tool_outputs(
        thread_id=thread_id,
        run_id=response.run_id,
        tool_outputs=tool_outputs
    )
    
    print(final_response.latest_message.content)
```

### Memory

```python
# Add a memory
await client.add_memory(
    assistant_id=assistant_id,
    content="User prefers Python programming",
    metadata={"category": "preference"}
)

# Get all memories
memories = await client.get_memories(assistant_id)
for memory in memories.memories:
    print(f"{memory.id}: {memory.content}")

# Get specific memory
memory = await client.get_memory(assistant_id, memory_id)

# Update memory
await client.update_memory(
    assistant_id=assistant_id,
    memory_id=memory_id,
    content="Updated content"
)

# Delete memory
await client.delete_memory(assistant_id, memory_id)

# Get memory stats
stats = await client.get_memory_stats(assistant_id)
print(f"Total memories: {stats.total_memories}")

# Use memory in conversation
response = await client.add_message(
    thread_id=thread_id,
    content="What do you know about me?",
    memory="Auto"  # Enable memory search and automatic updates
)
```


### Documents

```python
# Upload document to assistant
document = await client.upload_document_to_assistant(
    assistant_id=assistant_id,
    file_path="path/to/document.pdf",
)

# Upload document to thread
document = await client.upload_document_to_thread(
    thread_id=thread_id,
    file_path="path/to/document.pdf",
)

# List assistant documents
documents = await client.list_assistant_documents(assistant_id)

# List thread documents
documents = await client.list_thread_documents(thread_id)

# Get document status
document = await client.get_document_status(document_id)

# Delete document
result = await client.delete_document(document_id)
```

)

async def demo_err():
    try:
        await client.get_assistant("invalid_id")
    except BackboardNotFoundError:
        print("Assistant not found")
    except BackboardValidationError as e:
        print(f"Validation error: {e}")
