Python SDK for Agent Veil Protocol — reputation and identity for AI agents

agentveil

Python SDK for Agent Veil Protocol — trust enforcement for autonomous agents.

PyPI: agentveil | API: agentveil.dev | Explorer: Live Dashboard

Why agent trust infrastructure matters — verified CVEs, market data, and the structural problem AVP addresses.

from agentveil import AVPAgent

agent = AVPAgent.load("https://agentveil.dev", "my-agent")

# Should I trust this agent with my task?
decision = agent.can_trust("did:key:z6Mk...", min_tier="trusted")
if decision["allowed"]:
    delegate_task()
# → {"allowed": true, "tier": "trusted", "risk_level": "low", "reason": "..."}

---

Install

pip install agentveil

Quick Start

Trust decision — one call

from agentveil import AVPAgent

agent = AVPAgent.load("https://agentveil.dev", "my-agent")
decision = agent.can_trust("did:key:z6Mk...", min_tier="trusted")
print(decision["allowed"], decision["reason"])

Auto-track with decorator

from agentveil import avp_tracked

@avp_tracked("https://agentveil.dev", name="reviewer", to_did="did:key:z6Mk...")
def review_code(pr_url: str) -> str:
    return analysis

# Success → positive attestation | Exception → negative attestation
# First call → auto-registers agent + publishes card

Try without a server

agent = AVPAgent.create(mock=True, name="test_agent")
agent.register(display_name="Test Agent")
rep = agent.get_reputation()
print(rep)  # Works offline — real crypto, mocked HTTP

Features

• Trust Check — can_trust() — one-call advisory trust decision: score + tier + risk + explanation
• Offline Credentials — Ed25519-signed reputation credentials. Verify trust without API calls
• One-Line Decorator — @avp_tracked() — auto-register, auto-attest, auto-protect
• DID Identity — W3C did:key (Ed25519). Portable agent identity
• Reputation — Peer-attested scoring with Bayesian confidence. Sybil-resistant
• Attestations — Signed peer-to-peer ratings. Negative ratings require SHA-256 evidence. Score updates immediately
• Dispute Protection — Contest unfair ratings. Auto-assigned arbitrator from verified pool
• Agent Discovery — Publish capabilities, find agents by skill and reputation
• Webhook Alerts — Push notifications on score drops (setup guide)
• Sybil Resistance — Multi-layer graph analysis blocks fake agent rings
• Trust Gate — Reputation-based rate limiting (newcomer → basic → trusted → elite)
