Agentverse Deploy

Agentverse Deploy

Overview

Deploy Python code as a hosted agent on Agentverse. The agent runs on Fetch.ai's infrastructure — no server needed. Creates the agent, uploads code in the correct format, and optionally starts it.

When to Use

• User asks to "deploy this as an agent on Agentverse"
• User asks to "host this code on Agentverse"
• User asks to "create a new hosted agent"
• User has Python agent code they want to run on Agentverse

Prerequisites

• AGENTVERSE_API_KEY environment variable set
• Python 3.8+ with requests

Quick Steps

1. Deploy from a file

python3 scripts/deploy_agent.py --name "my-agent" --file ./my_agent_code.py --start

2. Deploy inline code

python3 scripts/deploy_agent.py --name "hello-agent" --code '
@agent.on_event("startup")
async def hello(ctx):
    ctx.logger.info("Hello from my agent!")
'

3. Parse the result

{
  "status": "success",
  "name": "my-agent",
  "address": "agent1q...",
  "running": true
}

Critical: Hosted Agent Code Rules

Your code MUST follow these rules for the hosted environment:

1. DO NOT create an Agent() instance — agent is pre-created by the platform
2. DO NOT call agent.run() — the platform manages the lifecycle
3. DO use @agent.on_event("startup") for initialization
4. DO use ctx.logger.info() for output (no print/stdout)
5. DO use Protocol objects and agent.include() for message handling

Valid hosted agent template:

from uagents import Context, Protocol

@agent.on_event("startup")
async def startup(ctx: Context):
    ctx.logger.info(f"Agent started: {ctx.agent.address}")

@agent.on_interval(period=60.0)
async def periodic(ctx: Context):
    ctx.logger.info("Running periodic task...")

With Chat Protocol:

from datetime import datetime
from uuid import uuid4
from uagents import Context, Protocol
from uagents_core.contrib.protocols.chat import (
    ChatMessage, ChatAcknowledgement, TextContent, chat_protocol_spec
)

protocol = Protocol(spec=chat_protocol_spec)

@protocol.on_message(ChatMessage)
async def handle(ctx: Context, sender: str, msg: ChatMessage):
    response = ChatMessage(
        timestamp=datetime.now(), msg_id=uuid4(),
        content=[TextContent(type="text", text="Hello! I received your message.")]
    )
    await ctx.send(sender, response)

agent.include(protocol, publish_manifest=True)

Code Upload Format

The API expects a specific format:

import json
files = [{"language": "python", "name": "agent.py", "value": your_code_string}]
payload = {"code": json.dumps(files)}  # code is a JSON STRING of a list

The deploy script handles this automatically.

Edge Cases

• Name conflicts: Agent names don't need to be unique — addresses are unique
• Code errors: Check logs after starting (agentverse-manage logs)
• Import errors: Only standard library + uagents + uagents_core available in hosted env
• File size: Keep code under 100KB
