x402 Protocol Surpasses 205 Million Transactions on Coinbase

The x402 protocol has reached a milestone of 205 million transactions on Coinbase's network. This open standard enables AI agents and automated applications to initiate payments directly over HTTP, without human intervention.

This means that machines can pay for services, data, or computational resources on demand, turning a standard web request into a payment instruction. The protocol's design is intentionally simple, leveraging existing web infrastructure to lower the barrier for developers integrating payments into AI workflows.

Coinbase currently accounts for 67% of the transaction volume, underscoring its early lead in this niche. However, other networks are also participating, and the open nature of the standard means competition and innovation are likely to follow.
