x402 is an open internet-native payments protocol built around HTTP 402 Payment Required. It lets APIs, apps, agents, models, data sources, and digital services charge directly inside a normal web request — no accounts, subscriptions, prepaid credits, or manual checkout.
This matters because AI agents will make tons of small automated purchases: API calls, data, inference, compute, research, content, and agent-to-agent services.
Why Solana fits x402
Solana fits because x402 needs fast, cheap, high-frequency payments. Low fees and fast settlement make Solana well-suited for micropayments, pay-per-use APIs, and machine-native agent commerce.
