x402 Pre-Flight Inspector

Test and simulate HTTP 402 Payment Requirements on Stellar before an AI agent signs. Verifies classic accounts, unwraps muxed accounts (MED...), and evaluates ledger evidence.

Agentic Pre-Flight Gate. The x402 protocol standardizes how an agent pays; Landfall answers who is safe to pay. Paste an x402 accepts array or 402 Payment Required JSON payload below. Landfall will inspect every counterparty against the public ledger and render the pre-flight authorization decision.
