sweetai-agent-firewall

Pre-transaction trust firewall for AI agents. Ask "should I pay agent X $N?" before any agent-to-agent payment — one call, $0.01, no API key, no subscription (x402 / USDC).

from sweetai_firewall import SweetAIFirewall

fw = SweetAIFirewall()
result = fw.should_i_pay(agent_id=55985, amount_usd=25)
if result.payment_required:
    # Settle result.raw['accepts'] with your x402 wallet, then repeat the call.
    raise RuntimeError("Settle SweetAI x402 payment before continuing")
if result.action != "PAY":
    raise RuntimeError(f"Transfer blocked: {result.action}")
print(result.verdict)
# pay 0.01 USDC on eip155:8453, ... to 0x... to unlock the 25.0 USD decision

After your agent settles the 0.01 USDC payment (x402 X-PAYMENT header), the same call returns the full decision:

result.action          # "PAY" / "CAUTION" / "SKIP"
result.confidence      # 0.0 - 1.0
result.expected_loss_usd  # expected loss sized to YOUR amount

What's under the hood

• ERC-8004 / Solana-8004 on-chain feedback analytics (Base, Ethereum, X Layer, Solana, Bittensor)
• Sybil forensics: reviewer concentration (Herfindahl), ghost-reviewer ratio, burst detection
• Liveness SLA: p50/p95 latency + flap counts, probed every 15 min
• x402 pay-per-call: 0.01 USDC per decision on Base/Polygon/Arbitrum/Avalanche/Sei/X Layer/Solana

Free surfaces (no payment needed)

fw.status()               # live index stats
fw.network_sybil_overview()  # risk tiers across all indexed agents
fw.pricing()              # current prices
