Agent Passport SDK

5-minute EU AI Act Art.50 compliance for AI Agents on Base.

Agent Passport is a compliance proof system that helps platforms ensure every AI agent they interact with carries verifiable proof of regulatory compliance — starting with Art.50 disclosure obligations.

Install

pip install agent-passport-agl

Quick Start

from agent_passport import AgentPassportClient, passport_guard, set_default_client

# Initialize (read-only)
client = AgentPassportClient(rpc_url="https://mainnet.base.org")
set_default_client(client)

# Protect your agent handler with one decorator
@passport_guard(required_scope=1)  # attribute_type=1 for Art.50
def handle(agent_id, query):
    return f"Compliant response to: {query}"

Register an Agent

client = AgentPassportClient(
    rpc_url="https://mainnet.base.org",
    private_key="0xYOUR_KEY"
)
agent_id = client.register_agent(
    name="MyAgent",
    operator="0xYourAddress",
    metadata_uri="https://example.com/metadata.json"
)
print(f"Registered agent with ID: {agent_id}")  # uint256, starts at 1

Art.50 Disclosure

from agent_passport import Art50ComplianceChecker

checker = Art50ComplianceChecker(client)
header = checker.generate_disclosure_header(agent_id, interaction_type="chat")
# => X-AI-Disclosure: agent=1; compliant=true; compliance_level=2; type=chat
