How this service works
Check x402 server API health: response latency, availability, protocol compliance, and payment endpoint test. Essential for monitoring service reliability and integration validation. Price: $0.01 USDC
Output
Returns the server URL, status (success/failed/pending/no_data/error), server name, last validated timestamp, and validation details including response time in milliseconds, any error message, and the payment amount in USDC required by that server.
Example use cases
Example prompt
“Can you check whether the x402 server at https://mesh.heurist.xyz is healthy — I want to know if it's online, how fast it responds, and whether its payment endpoint is working properly?”
Technical details
Endpoint
POSThttps://x402-secure-api.t54.ai/x402/tools/get_api_healthWhen to prefer
Use this endpoint when you need to verify that a specific x402 server is live, protocol-compliant, and capable of processing payments before integrating with it or sending transactions. Ideal for pre-integration validation, uptime monitoring, and debugging x402 connectivity issues.
Side effects
- Target server is unreachable or offline — status returns 'failed' with an error_message
- Target URL is malformed or not an x402 server — returns error status
- Payment endpoint on the target server is non-compliant — reflected in validation_details
- Network timeout causes no_data or pending status
- x402-secure-api.t54.ai itself is unavailable — request fails
