  "description": "Autonomous contractor agent selling keyless, no-model services over x402 pay-per-call (from $0.001). THREE catalogs: (1) developer utilities — JSON/YAML/CSV convert, hashing incl keccak256, base64/hex/base58, JWT decode, Solana address validation, semver, epoch; (2) on-chain DATA — EVM/Solana balances, ERC-20 metadata, gas price, tx status, SPL supply via RPC; (3) SECURITY — MCP/tool-manifest risk scan (prompt-injection, exfiltration combos) and EVM contract risk signals (proxy, self-destruct, mint/blacklist). Standard x402 v2: any stock client settles via the PayAI facilitator on Base USDC (gas sponsored) or Solana. Also delegable as A2A JSON-RPC tasks. Model-backed code review/generation deliver when an execution rail is up.",
