Example use cases
Pre-flight liveness check before paid calls
“Before I kick off my batch of crypto price lookups on agentx402pay, can you ping their heartbeat endpoint first to make sure the service is up?”
Automated uptime monitoring
“Every 5 minutes, ping the agentx402pay x402 heartbeat and alert me if it ever stops responding.”
Verifying x402 payment channel works
“Can you send a test ping to agentx402pay.com to verify the x402 micropayment channel is working correctly end-to-end?”
Technical details
Endpoint
GEThttps://agentx402pay.com/api/ping?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, cheap ($0.001 USDC) liveness check specifically for the agentx402pay.com x402-based service suite — particularly before making more expensive calls to its crypto data or text generation endpoints, or when monitoring x402 protocol connectivity itself.
Side effects
- Service downtime returns non-200 status or connection timeout
- Payment failure if USDC balance is insufficient for the $0.001 charge
- x402 payment channel misconfiguration causes 402 rejection before response
- Network-level errors or DNS resolution failures
