Example: REST API Usage

import requests

# Verify agent output
response = requests.post("http://localhost:8000/verify", json={
    "text": "The framework achieves 96.8% F1 score.",
    "agent_id": "apex-1687"
})
print(response.json())
# {"status": "pass", "violations": [], "latency_ms": 14.2}

# Create on-chain attestation
response = requests.post("http://localhost:8000/attestation/create", json={
    "proof_hash": "0x44b45cd...",
    "agent_id": "apex-1687",
    "verdict": "APPROVED"
})
print(response.json())
# {"tx_hash": "0x9f3a...", "chain": "avalanche", "block": 45823901}
