x402 In the past 30 days, it processed 75.41 million transactions.
Simply put, x402 is a payment protocol built for AI agents.
An agent calls a paid API, and the server responds with a 402 “payment required.” The agent then pays automatically, and requests again with the proof—no checkout page anywhere in the whole flow.
This week, Block added an x402 fund and brought the Bitcoin Lightning Network into the picture, because Lightning is naturally suited for small-value, high-frequency, real-time payments.
That said, the amounts aren’t as outrageous as you might think. The total value over 30 days is just $24.24 million, and Circle has said that 99.3% of the volume is routed through USDC.
How much Lightning will get is still unclear, and Cash App hasn’t said when it will roll out either.
With lots of transactions and small amounts, the average per transaction is a bit over $0.30. Agent payments are still in a trial phase, but this is already real traffic.
$BTC AI agents will pay for things going forward—will you back stablecoins or Bitcoin?
