agent-pulseSend and verify on-chain liveness pulses for autonomous agents on Base via the Agent Pulse protocol. Use when you need to: (1) prove an agent is alive by sending a pulse, (2) check any agent's liveness status or streak, (3) monitor multiple agents, (4) view the global pulse feed, (5) auto-configure wallet and PULSE balance, (6) run scheduled heartbeat pulses, or (7) read protocol health and config. Supports both API and direct on-chain (cast) modes.
uniswap-v4Swap tokens and read pool state on Uniswap V4 (Base, Ethereum). Use when the agent needs to: (1) swap ERC20 tokens or ETH via Uniswap V4, (2) get pool info (price, tick, liquidity, fees), (3) find the best pool for a token pair, (4) quote expected swap output via the on-chain V4Quoter, (5) set up Permit2 approvals for the Universal Router, or (6) execute exact-input swaps with proper slippage protection. Supports Base and Ethereum mainnet, plus Base Sepolia testnet. TypeScript with strict types. Write operations need a private key via env var.
