x402 Doctor: endpoint diagnosis

● verified · developer.x402-audit · 0.01 USDC/call · base, solana

Diagnose any x402 endpoint the way a paying agent would: the 402 challenge and envelope, every accepts option (network, asset, amount, payee, EIP-712 domain), the Solana payout account, Bazaar discovery and which wallets can pay. Pass/warn/fail per check. Never pays the endpoint.
