How this service works
x402-paid deterministic utilities for autonomous agents
Output
Returns a JSON object with a single boolean field 'ok' set to true, confirming the service is live and the x402 payment was accepted. If an echo query parameter was supplied, the response may reflect it back.
Example use cases
Pre-flight check before agent workflow
“Before my agent kicks off the full pipeline, ping the NEXUS x402 utilities endpoint to confirm the service is reachable and the payment flow is working — I need a green light before proceeding.”
Testing x402 payment integration
“I just set up x402 USDC payments for my autonomous agent — can you hit the NEXUS ping endpoint to verify that the payment handshake completes correctly and I get an ok response back?”
Monitoring x402 service uptime
“Check if the NEXUS agent utilities service is currently up and responding — ping it now and tell me if it returns ok true so I know whether my agent can depend on it.”
Technical details
Endpoint
GEThttps://x402.nexusword.it/v1/ping?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that (1) the NEXUS x402 utilities service is online and (2) your agent's x402 micro-payment flow is functioning correctly before invoking more expensive or consequential endpoints. Prefer it over generic HTTP health checks when you specifically need to validate end-to-end x402 payment capability against a live paid endpoint.
Side effects
- Payment rejected (402) — x402 payment token invalid or funds insufficient
- Service unavailable (503) — NEXUS backend is down
- Timeout — endpoint unreachable, network issue
- Invalid method — only GET is accepted; POST/PUT return 405
- Malformed payment header — x402 facilitator cannot process the payment metadata
