POST /dev/x402-probe

live

x402 probe: requests a URL without paying and decodes its 402 payment terms: x402 version, accepted schemes and networks (CAIP-2), price in USDC (atomic and human), payTo address, asset contract, max timeout, resource description, and whether the terms came from the PAYMENT-REQUIRED header or the JSON body. Tells an agent exactly what a paid API costs before it commits. $0.01 per probe.

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