Synchronous vs Asynchronous Guide

This guide explains the differences between synchronous and asynchronous programming patterns in the AgentBay Python SDK.

Overview

The AgentBay Python SDK provides both synchronous and asynchronous APIs to accommodate different use cases and programming styles.

When to Use Synchronous API

Use the synchronous API (AgentBay) for:

• Simple scripts and CLI tools
• Learning and experimentation
• Sequential operations where concurrency is not needed

When to Use Asynchronous API

Use the asynchronous API (AsyncAgentBay) for:

• Web servers (FastAPI, Django)
• High-concurrency applications
• Applications that need to handle multiple sessions simultaneously

Code Examples

Synchronous Example

from agentbay import AgentBay, CreateSessionParams

# Create client
agentbay = AgentBay(api_key="your_api_key")

# Create session
result = agentbay.create(CreateSessionParams())
session = result.session

# Use session
result = session.command.execute_command("echo 'Hello World'")
print(result.output)

# Cleanup
session.delete()

Asynchronous Example

import asyncio
from agentbay import AsyncAgentBay, CreateSessionParams

async def main():
    # Create client
    agentbay = AsyncAgentBay(api_key="your_api_key")
    
    # Create session
    result = await agentbay.create(CreateSessionParams())
    session = result.session
    
    # Use session
    result = await session.command.execute_command("echo 'Hello World'")
    print(result.output)
    
    # Cleanup
    await session.delete()

# Run async function
asyncio.run(main())

Key Differences

Aspect	Synchronous	Asynchronous
Import	from agentbay import AgentBay	from agentbay import AsyncAgentBay
Method calls	session.command.execute_command()	await session.command.execute_command()
Error handling	Standard try/except	Async try/except
Concurrency	Sequential	Concurrent with asyncio

Migration Guide

To migrate from synchronous to asynchronous code:

1. Change imports from AgentBay to AsyncAgentBay
2. Add async keyword to function definitions
3. Add await keyword before SDK method calls
4. Use asyncio.run() to execute the main function

For migrating from backup versions or between sync/async, see Migration Guide.
