# AWS Lambda

## Prerequisites

The following example requires the `boto3` library.

```shell theme={null}
pip install openai boto3
```

## Example

The following agent will use AWS Lambda to list all Lambda functions in our AWS account and invoke a specific Lambda function.

```python cookbook/tools/aws_lambda_tools.py theme={null}

from phi.agent import Agent
from phi.tools.aws_lambda import AWSLambdaTool


# Create an Agent with the AWSLambdaTool
agent = Agent(
    tools=[AWSLambdaTool(region_name="us-east-1")],
    name="AWS Lambda Agent",
    show_tool_calls=True,
)

# Example 1: List all Lambda functions
agent.print_response("List all Lambda functions in our AWS account", markdown=True)

# Example 2: Invoke a specific Lambda function
agent.print_response("Invoke the 'hello-world' Lambda function with an empty payload", markdown=True)
```
