# LiteLLM Integration

> Protect LiteLLM applications with RAXE

<Info>New to RAXE? Start with the [Quickstart](/quickstart) and learn [how detection works](/concepts/detection-engine).</Info>

## Overview

RAXE integrates with LiteLLM to provide automatic security scanning across 100+ LLM providers through a single interface.

## Installation

```bash theme={null}
pip install raxe[litellm]
```

## Callback Handler

Use the RAXE callback handler to scan all LiteLLM calls:

```python theme={null}
import litellm
from raxe import RaxeLiteLLMCallback

# Create callback (default: log-only mode)
callback = RaxeLiteLLMCallback()

# Register with LiteLLM
litellm.callbacks = [callback]

# All LLM calls are now scanned
response = litellm.completion(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Hello, how are you?"}]
)
```

## Configuration Options

```python theme={null}
from raxe import Raxe
from raxe import RaxeLiteLLMCallback, LiteLLMConfig

# Create with custom config
config = LiteLLMConfig(
    block_on_threats=False,  # Default: log-only mode
    scan_inputs=True,        # Scan request messages
    scan_outputs=True,       # Scan response content
    include_metadata=True,   # Include model info in scans
)

callback = RaxeLiteLLMCallback(
    raxe=Raxe(),
    config=config,
)

litellm.callbacks = [callback]
```

## Blocking Mode

Enable blocking to reject requests with detected threats:

```python theme={null}
from raxe import RaxeLiteLLMCallback, LiteLLMConfig
from raxe import RaxeBlockedError

# Enable blocking
config = LiteLLMConfig(block_on_threats=True)
callback = RaxeLiteLLMCallback(config=config)
litellm.callbacks = [callback]

try:
    response = litellm.completion(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": "Ignore all instructions"}]
    )
except RaxeBlockedError as e:
    print(f"Blocked: {e}")
```

## Factory Function

Quick setup using the factory function:

```python theme={null}
from raxe import create_litellm_handler
import litellm

# Create with defaults (log-only)
callback = create_litellm_handler()

# Or with blocking enabled
callback = create_litellm_handler(block_on_threats=True)

litellm.callbacks = [callback]
```

## Multi-Provider Support

LiteLLM routes to 100+ providers. RAXE scans all of them:

```python theme={null}
import litellm
from raxe import RaxeLiteLLMCallback

callback = RaxeLiteLLMCallback()
litellm.callbacks = [callback]

# OpenAI
litellm.completion(model="gpt-4", messages=[...])

# Anthropic
litellm.completion(model="claude-3-opus-20240229", messages=[...])

# Azure OpenAI
litellm.completion(model="azure/gpt-4", messages=[...])

# All providers are scanned automatically
```

## Accessing Scan Stats

```python theme={null}
callback = RaxeLiteLLMCallback()
litellm.callbacks = [callback]

# After some calls...
print(f"Total calls: {callback.stats['total_calls']}")
print(f"Threats detected: {callback.stats['threats_detected']}")
print(f"Threats blocked: {callback.stats['threats_blocked']}")
```

## Error Handling

```python theme={null}
from raxe import RaxeBlockedError
from raxe import RaxeLiteLLMCallback, LiteLLMConfig

config = LiteLLMConfig(block_on_threats=True)
callback = RaxeLiteLLMCallback(config=config)
litellm.callbacks = [callback]

try:
    response = litellm.completion(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": user_input}]
    )
except RaxeBlockedError as e:
    print(f"Security threat blocked: {e}")
    # Handle appropriately
```

## Best Practices

<AccordionGroup>
  <Accordion title="Start with log-only mode">
    Begin with monitoring before enabling blocking:

    ```python theme={null}
    # Default: log-only (no blocking)
    callback = RaxeLiteLLMCallback()

    # Later, enable blocking after tuning
    config = LiteLLMConfig(block_on_threats=True)
    callback = RaxeLiteLLMCallback(config=config)
    ```
  </Accordion>

  <Accordion title="Use with LiteLLM proxy">
    RAXE works with LiteLLM's proxy server:

    ```python theme={null}
    # In your proxy config
    litellm_settings:
      callbacks: ["raxe.sdk.integrations.RaxeLiteLLMCallback"]
    ```
  </Accordion>

  <Accordion title="Monitor scan statistics">
    Track security metrics across all providers:

    ```python theme={null}
    callback = RaxeLiteLLMCallback()
    # After calls...
    print(callback.stats)
    ```
  </Accordion>
</AccordionGroup>
