You supply a target URL and the service probes it, returning response latency, payment amount, protocol compliance status, and validation details. This is useful for monitoring the uptime and correctness of x402 payment-gated APIs before routing agent traffic to them.\n\nThe endpoint itself is x402-gated at $0.01 USDC on the Base network (exact payment scheme). It accepts a POST request with a JSON body containing a single required field `url` — the x402 server you want to check. The response includes the server name, a status enum (success, failed, pending, no_data, error), detailed validation results (response time in ms, payment amount in USDC, result data, error messages), and a last-validated timestamp.\n\nThe service is part of the broader x402-secure platform, an open-source SDK and proxy that adds risk assessment and security layers on top of the x402 protocol. The platform supports both Base and Solana chains. No OpenAPI spec or dedicated docs page was found for this specific endpoint; the schema is derived entirely from the x402 challenge's `outputSchema` field.","tags":[],"capabilities":["x402-health-check","api-monitoring","latency-measurement","protocol-compliance-validation","payment-endpoint-testing","x402-protocol","base-network"],"categories":["monitoring","infrastructure","crypto"],"synonyms":["x402 server health check","API uptime monitor","x402 availability test","payment endpoint probe","x402 compliance checker","service reliability check","x402 status monitor"],"warnings":["No OpenAPI specification or dedicated API documentation found — /docs, /api, /pricing, /README all return 404.","Example response is inferred from the outputSchema, not from an actual observed response.","Pricing is only known from the x402 challenge description ($0.01 USDC); no formal pricing page exists."],"endpointUrl":"https://x402-secure-api.t54.ai/x402/tools/get_api_health","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x0495d60c927B97d67D5018C6AA65C9b2bebaeED9","scheme":"exact","channel":"crypto-base","network":"base","mimeType":"application/json","resource":"https://x402-secure-api.t54.ai/x402/tools/get_api_health","description":"Check x402 server API health: response latency, availability, protocol compliance, and payment endpoint test.
