Full demo with reply

Here are the basic steps to create a simple agent:

import os
from pinai_agent_sdk import PINAIAgentSDK, AGENT_CATEGORY_SOCIAL

# Initialize the SDK client
API_KEY = os.environ.get("PINAI_API_KEY", "your_api_key_here")
# For blockchain integration (optional) init in  PINAIAgentSDK.
PRIVATE_KEY = os.environ.get("ETHEREUM_PRIVATE_KEY")
RPC_URL = os.environ.get("BLOCKCHAIN_RPC_URL", "https://sepolia.base.org")

client = PINAIAgentSDK(api_key=API_KEY)

# Define message handling function
def handle_message(message):
    """
    Process incoming messages and respond
    
    Args:
        message (dict): Message object with format:
            {
                "session_id": "unique-session-id",
                "id": 12345,  # Message ID
                "content": "user message text",
                "created_at": "2023-01-01T12:00:00"
            }
    """
    print(f"Received: {message['content']}")

    session_id = message.get("session_id")
    if not session_id:
        print("Message missing session_id, cannot respond")
        return
    
    # Get user's message
    user_message = message.get("content", "")

    # Get persona info
    persona_info = client.get_persona(session_id)
    
    # Create your response (this is where your agent logic goes)
    response = f"Echo: {user_message}"
    
    # Send response back to user
    client.send_message(content=response)
    print(f"Sent: {response}")

# Register a new agent
agent_info = client.register_agent(
    name="My Hackathon Agent",
    description="A simple agent built during the hackathon",
    category=AGENT_CATEGORY_SOCIAL
)
agent_id = agent_info.get("id")
print(f"Agent registered with ID: {agent_id}")

# Start the agent and listen for messages
print("Starting agent... Press Ctrl+C to stop")
client.start_and_run(
    on_message_callback=handle_message,
    agent_id=agent_id
)

Core Concepts

Agent

An agent is the intelligent assistant you create that can interact with users. Each agent has a unique ID, name, description, and category.

Session

A session represents a conversation with a user. Each session has a unique session_id used to track interactions with a specific user.

Message

A message is the unit of information exchanged between the agent and users. Messages can contain text content and media (images, videos, audio, or files).

Agent Categories

PINAI platform supports the following agent categories:

Category Constant	Display Name	Description
AGENT_CATEGORY_SOCIAL	Social	Social agents
AGENT_CATEGORY_DAILY	Daily Life/Utility	Daily life and utility agents
AGENT_CATEGORY_PRODUCTIVITY	Productivity	Productivity tool agents
AGENT_CATEGORY_WEB3	Web3	Web3-related agents
AGENT_CATEGORY_SHOPPING	Shopping	Shopping agents
AGENT_CATEGORY_FINANCE	Finance	Finance agents
AGENT_CATEGORY_AI_CHAT	AI Chat	AI chat agents
AGENT_CATEGORY_OTHER	Other	Other types of agents

    metadata={"key": "value"},  # Optional: Additional metadata
    agent_owner="0x123..."  # Optional: Ethereum address of the agent owner (for blockchain registration)
)

Unregistering an Agent

result = client.unregister_agent(agent_id=123)

Starting an Agent

# Blocking mode (until Ctrl+C)
client.start_and_run(
    on_message_callback=handle_message,
    agent_id=123
)

Sending Messages

response = client.send_message(
    content="Hello, world!",  # Required: Message content
    session_id="unique-session-id",  # Optional: Session ID
    media_type="image",  # Optional: Media type, default is "none"
    media_url="https://example.com/image.jpg",  # Optional: Media URL
    meta_data={"key": "value"}  # Optional: Additional metadata
)

Getting User Information

persona = client.get_persona(session_id="unique-session-id")

Uploading Media

media_info = client.upload_media(
    file_path="/path/to/image.jpg",  # File path
    media_type="image"  # Media type: "image", "video", "audio", "file"
)
media_url = media_info.get("url")

Media Types and Limitations

Media Type	Supported Extensions	Size Limit
image	.jpg, .jpeg, .png, .gif, .webp	10MB

Error Handling

The SDK provides various exception types to help handle different error scenarios:

• AuthenticationError: API authentication failure (401 errors)
• PermissionError: Insufficient permissions (403 errors)
• ResourceNotFoundError: Requested resource not found (404 errors)
• ResourceConflictError: Resource conflict (409 errors)
• ValidationError: Request validation failure (400 errors)
• ServerError: Server returns 5xx errors
• NetworkError: Network connection issues
• Web3Error: Blockchain interaction failures

Example:

try:
    client.send_message(content="Hello")
except ValidationError as e:
    print(f"Validation error: {e}")
except AuthenticationError as e:
    print(f"Authentication error: {e}")
except Exception as e:
    print(f"Other error: {e}")

Best Practices

1. Securely Store API Keys

Don't hardcode API keys in your code. Use environment variables or secure key management services.

import os
API_KEY = os.environ.get("PINAI_API_KEY")

2. Implement Robust Message Handling

Always check if messages contain necessary fields and handle exceptions properly.

def handle_message(message):
    if not message or "content" not in message:
        print("Received invalid message")
        return
    
    session_id = message.get("session_id")
    if not session_id:
        print("Message missing session_id, cannot respond")
        return
    
    # Process message...

3. Use Asynchronous Processing for Long-Running Tasks

For tasks that require long processing times, consider using asynchronous processing to avoid blocking the message loop.

4. Regularly Save Agent State

If your agent needs to maintain state, save it regularly to prevent data loss.

5. Monitoring and Logging

Implement appropriate logging and monitoring to track your agent's performance and issues in production.

Example Applications

Echo Bot

def handle_message(message):
    session_id = message.get("session_id")
    content = message.get("content", "")
    
    # Simply reply with the user's message
    client.send_message(
        content=f"You said: {content}",
        session_id=session_id
    )

Image Generation Bot

def handle_message(message):
    """
    Process incoming messages and respond
    
    Args:
        message (dict): Message object with format:
            {
                "session_id": "unique-session-id",
                "id": 12345,  # Message ID
                "content": "user message text",
                "created_at": "2023-01-01T12:00:00"
            }
    """
    print(f"Received: {message['content']}")

    session_id = message.get("session_id")
    if not session_id:
        print("Message missing session_id, cannot respond")
        return
    
    # Get user's message
    user_message = message.get("content", "")

    # Get persona info
    persona_info = client.get_persona(session_id)
    
    # Create your response (this is where your agent logic goes)
    response = f"Echo: {user_message}"
    
    # Send response back to user
    client.send_message(content=response)
    print(f"Sent: {response}")

5. Security: Never expose your API key in client-side code or public repositories.

Example Integration

Here's a simple Python example of how to register an agent:

import requests

api_key = "your_api_key_here"
api_url = "https://api.pin.ai/api/sdk/register_agent"

headers = {
    "x-api-key": api_key,  # Required
    "Content-Type": "application/json"
}

data = {
    "name": "My Hackathon Agent",  # Required
    "url": "https://myproject.example.com",  # Optional
    "wallet": "0x123456789abcdef",  # Optional
    "category": "entertainment",  # Optional
    "cover": "https://myproject.example.com/cover.jpg",  # Optional
    "description": "An amazing agent built for the hackathon"  # Required
}

response = requests.post(api_url, json=data, headers=headers)

if response.status_code == 200:
    agent = response.json()
    print(f"Agent created with ID: {agent['id']}")
else:
    print(f"Error: {response.status_code} - {response.text}")
