x402 is a new way to make payments on the web.
It finally puts the “HTTP 402 – Payment Required” code to real use. Instead of accounts, API keys, or messy subscriptions, you just pay directly when you need something.
1⃣One request
2⃣tiny payment
3⃣instant access.
It’s perfect for APIs, apps, and even AI agents.
Developers can add payments with a single line of code.
Users only pay for what they use.
AI agents can automatically pay for data or services in real time.
Think of it like the missing piece of the internet:
a universal, lightweight way to charge (and pay) per request.
The web has always had “402 Payment Required” reserved.
Now x402 finally brings it to life.
☑️No accounts.
☑️No subscriptions.
Just simple, open, pay-per-use.
