Long-form thinking on pay-per-request APIs, HTTP 402, and the Solana payment layer for the machine economy.
Machine-to-Machine Payments Are Coming Faster Than Anyone Prepared For
AI agents need to transact autonomously. HTTP 402 on Solana is the infrastructure layer the Internet has been missing.
Pay-Per-Request APIs Are the Next Primitive of the Internet
Subscriptions are a workaround. The real model is charging exactly for what's used - per request, on-chain.
A Self-Monetizing API in 20 Lines of Code
A hands-on tutorial: build a pay-per-request API server, a client that pays automatically, and a real integration test suite - no Stripe, no auth, no database. Free on Solana devnet.
The Infrastructure Gap: Why the Machine Economy Is Stalling and How We Fix It
The machine economy isn't moving because payment infrastructure doesn't exist for machines. This piece outlines the path forward.
