The AI Era Needs New Payment Rails

AI agents are becoming autonomous economic actors, but legacy payment systems weren't built for them.

🚫

Designed to Block Machines

  • CAPTCHAs and two-factor auth
  • Anti-fraud systems flag automated transactions
  • Require human verification at every step
💸

Can't Handle Micropayments

  • High per-transaction fees (2-3% + fixed costs)
  • Paying $0.30 in fees for a $0.10 API call makes no sense
  • No support for sub-cent transactions
🐌

Too Slow for Real-Time Commerce

  • ACH transfers take 1-3 days to settle
  • Credit cards have rolling chargeback windows
  • Agents need instant payment finality

How It Works

Built on the HTTP 402 "Payment Required" status code, x402 makes payments as simple as an HTTP request.

1

Request Resource

Client requests a protected URL or API endpoint

2

Payment Required

Server returns HTTP 402 with payment instructions

3

Execute Payment

Client pays and obtains proof of transaction

4

Verify & Settle

Facilitator verifies payment and settles funds

5

Access Granted

Server delivers the protected resource
