Today we’re diving into HTTP 402 (Payment Required) and the X402 protocol — an open standard that enables micropayments and pay-per-use directly on the internet. Built on Solana, X402 lets apps charge fractions of a cent for API calls, content access, or AI agent interactions — no subscriptions, no ads, just seamless payments.

We’ll go step-by-step through the specification, explain how facilitators simplify the backend, and compare them with native Solana implementations. Then we’ll explore real examples using Corbit, Google A2A agents, and Coinbase’s reference SDK — plus all major SDKs with Solana support.

Perfect for developers building AI tools, APIs, paywalls, DePIN devices, or data dashboards that monetize per request.
