The .env file is created when you download your agent code:
xpander init
This downloads your agent code from the platform with the .env file pre-configured with your keys.
async_task_example.py
from dotenv import load_dotenvload_dotenv()from xpander_sdk import Task, Backend, on_taskfrom agno.agent import Agent@on_taskasync def task_handler(task: Task): backend = Backend() agno_args = await backend.aget_args(task=task) agno_agent = Agent(**agno_args) # Get files and images for comprehensive processing files = task.get_files() # PDF files as Agno File objects images = task.get_images() # Image files as Agno Image objects # Process task asynchronously with file support result = await agno_agent.arun( input=task.to_message(), # Includes text + file content files=files, # PDF files images=images # Image files ) task.result = result.content return task
This example shows non-blocking task processing where multiple tasks can be handled concurrently without blocking other operations. It uses asynchronous backend initialization with aget_args() for optimal resource utilization, automatic file categorization and handling for Agno integration, and task-to-message conversion with proper result handling.
