Api Endpoint

Textokit

x402 payment test and ping: one call with no required parameters returns server time (ISO 8601 and Unix ms), a request id, the seller payTo, chain id and an echo of your optional text, only after a real settlement. Use this when an agent needs to prove its payment flow works, measure round-trip latency or run a cheap scheduled canary against a live seller. No upstream, no model inference; paid round trip 1 to 2 s. Free sample at /api/x402-ping/sample.
