x402 agent
Agent Playground
Configure an autonomous agent's spending policy, then watch it fetch a real 402 challenge from the live facilitator and decide — on its own — whether to pay. Looking costs nothing: without a wallet the agent only reads the real challenge and renders its verdict. Nothing here is simulated.
