x402 v2 further promotes the development of the AI ​​Agent economy

The most important aspect of x402 is that it has driven the development of the AI ​​agent economy. The arrival of x402 v2 takes it a step further.

Before x402, each question asked, each graph calculated, or each webpage crawled by an AI agent might cost $0.001 or even less. At this point, if using a traditional credit card or Stripe for payment, the transaction fee would start at $0.30.

In other words, while traditional internet payment is well-developed, it is not suitable for the micro-payment scenarios of AI agents. Each $0.001 API call is not suitable for payment with a credit card or Stripe because the transaction fee (approximately 2-3% + $0.30) is far higher than the payment amount.

Moreover, AI agents are not human; they cannot open bank accounts, top up gas, enter passwords, or click confirmation, which would be a major inconvenience for them.
