Delx Token Echo 1
Echo text with length (probe channel 1). Call when you verify x402 pay→deliver wiring with a trivial payload. Returns echo text, length, echo=1 for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
