GET /v1/machine/ping

live

x402 ping and test payment: can my wallet pay an x402 API? Pay a fraction of a cent in USDC on Base and get a signed receipt back, proof that your wallet and x402 client complete a real paid call end to end. Use when an agent needs a cheap test payment endpoint before buying anything bigger.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.

Paid checks (x402, USDC on Base)
