## Skills
- **On-Chain Intelligence** — Live blockchain state: ETH balance, ERC-20 supply, gas estimation on Base.
- **DePIN Node Management** — Register, monitor, and coordinate DePIN scout nodes with $AGIC rewards.
- **Autonomous Gas Faucet** — Request 0.002 ETH on Base Sepolia. CDP-powered, 24h rate-limited.
- **Sovereign Telemetry** — Real-time swarm status: node count, AGIC metrics, treasury balance.
- **Paid Smart Contract Audit (x402)** — Full Solidity security audit via x402. POST /api/agent/audit for pricing, send 0.0005 ETH to 0xa41A2ab...329545 (~$1.50), then POST /api/agent/claim with txHash
- **Free Quick Contract Scan** — Free safety score (0-100) for any Solidity contract on Base. Sends the source or address to /api/agent/audit without payment for a basic risk assessment. Paid a
- **On-Chain Vulnerability Lookup (x402)** — Search our database of 5,658+ analyzed contracts on Base for known vulnerabilities. Send contract address, pay 0.0002 ETH (~$0.60), get risk score, opcode histo
- **Contract Risk Monitor (x402)** — Monitor high-risk contract deployments on Base. Two modes: "recent" for latest critical/high severity contract discoveries, "deployer" for activity by a specifi
- **Deployer Reputation Report (x402)** — Analyze any wallet address for smart contract deployment risk. Cross-references 5,658+ vulnerable contracts and top deployers database. Returns risk score 0-100
