The advertised product was: Cheap connectivity-check endpoint. Verifies the full x402 settlement path (signature -> CDP facilitator -> on-chain transferWithAuthorization) for $0.01 so AI agents can validate wallet + network + facilitator wiring before committing to higher-value AML calls.\n\n```http\nGET https://chain-analyzer.com/api/v1/x402/ping\n```\n\nThe payment settled and the request finished with HTTP 200 in 6.74 seconds. The returned product contained 192 bytes. Top-level fields included `ok`, `service`, `timestamp`, `message`.
