Liquid Agent: Money Tools for AI Agents

x402 money tools for AI agents: a one-signature USDC bridge from Base to 16 chains, the live Polymarket price to beat (BTC, ETH, SOL, XRP on 5m and 15m), a tokenized US stock basket from $1, and gas paid in USDC, plus free USDC and x402 debugging tools and a remote MCP server (28 tools).

Reads free; transactions return unsigned…
