What does x402 actually do?

X402 resurrects an unused HTTP status code to create a native payment layer for the web. When a website or API wants payment, it responds with HTTP 402. The client (user or AI agent) pays, and access is granted. It's designed for automated, frequent, low-friction transactions.

Will x402 replace existing payment processors like Stripe or PayPal?

Unlikely in the near term. X402 is better suited for agent-to-service payments, API access, and micro-transactions. Traditional e-commerce will probably keep using Stripe, PayPal, and credit cards for years. But x402 could dominate specific use cases—especially in AI-driven commerce.

Can I use x402 right now?

Yes. Solana's ecosystem is already using it, and developers can experiment with the protocol now. But mainstream adoption will take time as more companies join the foundation and build tooling around it.
