x402 Doctor

Activex402

Checks x402 paid APIs before an agent pays and before a seller ships: a $0.001 preflight (go / caution / no_go, plus the cheapest option that will settle), batch and deep preflight, a $0.01 full diagnosis with a fix hint per check, and the fix code for $0.05. Paid per call over x402 in USDC on Base or Solana; the web check is free.
