Building an AI Agent That Pays for Data: A Practical x402 Walkthrough.

Building an AI Agent That Pays for Data: A Practical x402 Walkthrough. A working implementation walkthrough for an AI agent consuming an x402-gated API: reading the 402 response and its accepts array, choosing a payment method (facilitator-settled transaction vs self-submitted reference), building the payment, and handling the settlement-lag retry loop — using this site’s own live Watchdog endpoints as the worked example.
