Episode notes

Micropayments were always meant to be part of the internet, but the technology never existed to make them work.

Until now. David sits down with Sam Ragsdale, CEO of Merit Systems, to unpack x402, a new protocol reviving the long-dormant “Payment Required” status code to enable crypto-powered microtransactions across the web.

They explore how x402 could transform how machines, AI agents, and humans pay for internet resources, reshape online business models beyond ads, and unlock a new economy of autonomous agents and programmable commerce.
