Technical details
Endpoint
POSThttps://www.qrbase.xyz/api/x402/pingWhen to prefer
Use this endpoint when you need to test or validate an x402 micropayment flow at the lowest possible cost (0.001 USDC), rather than the sibling 100 USDC endpoint. Ideal for integration testing, connectivity checks, or confirming x402 protocol functionality without significant cost.
Side effects
- Insufficient USDC balance — payment cannot be processed
- Invalid x402 payment header — returns 402 Payment Required
- Network unavailable — endpoint unreachable
- Base network congestion causing transaction delay
- Malformed POST request — returns 400 Bad Request
