How this service works
Servicios para trabajar con textos en Argentina: cartas de reclamo, resúmenes con citas, comparación, traducción y solicitudes. Pagá en pesos con Mercado Pago.
Output
A JSON object containing the current server time in ISO 8601 format, Unix timestamp in milliseconds, a unique request ID, the seller's payTo wallet address, the chain ID (Base), and an echo of any optional text you supplied — all returned only after real on-chain USDC settlement.
Example use cases
CI canary for x402 payment pipeline
“After every deployment, ping the Textokit x402 endpoint with echo text 'deploy-check' to confirm our payment flow is still working end to end on Base.”
First-time x402 wallet validation
“I just set up my USDC wallet on Base — can you do a live x402 ping to Textokit to prove the payment settles correctly and show me the seller's payTo address?”
Scheduled latency monitoring
“Every 15 minutes, fire a paid ping at Textokit's x402 endpoint and log the round-trip time and server timestamp so I can track payment settlement latency over time.”
Technical details
Endpoint
POSThttps://tienda.textokit.store/api/x402-ping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a real x402 micropayment flow works end to end on Base — not just mock or simulated payments. It is the cheapest and most direct way to prove settlement, measure latency, or run a scheduled canary against a live seller without any upstream dependencies or model inference overhead.
Side effects
- Insufficient USDC balance causes payment settlement failure before response
- Wallet not configured for Base network results in chain mismatch error
- Echo text exceeding 200 characters is rejected with validation error
- Network timeout during settlement (1-2s window) may cause incomplete round trip
- Free sample endpoint at /api/x402-ping/sample bypasses payment but returns limited data
