agentstamp 1.2.0

Identity lifecycle SDK for Python AI agents — trust stamps, registry, heartbeats, auto-renewal

agentstamp

Identity lifecycle SDK for Python AI agents. Works with CrewAI, AutoGen, LangGraph, and any Python agent framework.

Register your agent, mint trust stamps, send heartbeats, and auto-renew — in 3 lines.

Install

pip install agentstamp

Quick Start

from agentstamp_crewai import AgentStampLifecycle

lifecycle = AgentStampLifecycle(
    wallet_address="0xYourWalletAddress",
    name="MyAgent",
    description="What your agent does",
    category="research",
)
lifecycle.start()  # stamps + registers + heartbeats + auto-renew

That's it. Your agent now has:

• A cryptographic identity stamp (Ed25519)
• A public registry listing
• Heartbeat-based uptime reputation
• Auto-renewal before expiry

Verify Other Agents

trust = lifecycle.check_trust("0xOtherAgentWallet")
if trust.get("trusted"):
    print(f"Verified: {trust['agent']['name']} (score: {trust['reputation']['score']})")
else:
    print("Unverified agent — proceed with caution")

Gate Functions Behind Verification

from agentstamp_crewai import stamp_verified

@stamp_verified(lifecycle)
def sensitive_operation(data: str) -> str:
    """Only runs if the agent is AgentStamp verified."""
    return process(data)

CrewAI Integration

from crewai import Agent, Task, Crew
from agentstamp_crewai import AgentStampLifecycle

# Start lifecycle
lifecycle = AgentStampLifecycle(
    wallet_address="0x...",
    name="ResearchBot",
    description="Finds and summarizes papers",
    category="research",
)
lifecycle.start()

# Create CrewAI agent as normal
agent = Agent(
    role="Researcher",
    goal="Find relevant papers",
    backstory="Expert research assistant",
)

# Check trust before collaborating with other agents
trust = lifecycle.check_trust("0xCollaboratorWallet")
