Agent Update

Update an existing agent’s configuration and re-register the changes.

Python

from agent0_sdk import SDK
import os

# Initialize SDK
sdk = SDK(
    chainId=11155111,  # Ethereum Sepolia testnet
    rpcUrl=os.getenv("RPC_URL"),
    signer=os.getenv("PRIVATE_KEY"),
    ipfs="pinata",
    pinataJwt=os.getenv("PINATA_JWT")
)

# Load existing agent
agent = sdk.loadAgent("11155111:123")

print(f"Current: {agent.name}")

# Update information
agent.updateInfo(
    name="Updated Agent Name",
    description="New description",
    image="https://example.com/new-image.png"
)

# Update endpoints
agent.setMCP("https://new-mcp.example.com/")
agent.setA2A("https://new-a2a.example.com/agent.json")

# Update wallet
agent.setAgentWallet("0xNewWalletAddress", chainId=11155111)

# Update metadata
agent.setMetadata({
    "version": "2.0.0",
    "new_field": "new_value"
})

# Change status
agent.setActive(True)
agent.setX402Support(True)

# Re-register (uploads new file, updates on-chain)
agent.registerIPFS()

print(f"✅ Updated and re-registered: {agent.agentId}")

# Verify changes
retrieved = sdk.getAgent(agent.agentId)
print(f"Name: {retrieved.name}")
print(f"Description: {retrieved.description}")
