Chainalysis Reports 138 Million Crypto Payments Processed by AI Agents via x402 Protocol

A recent report from Chainalysis highlights the significant role of autonomous AI agents in the cryptocurrency landscape, revealing that these agents have executed more than 138 million payments through the x402 protocol, which is designed for automated transactions.

Most of these transactions are small, with over 87% categorized as micropayments, typically ranging from a hundredth of a cent to ten cents. This indicates a growing trend in the use of AI for microtransactions in various online services.

The x402 protocol allows AI agents to conduct transactions independently, without requiring human intervention. Chainalysis notes that users are becoming increasingly strategic in their use of this technology, as evidenced by a dramatic decrease in the time between a wallet's initial funding and its first x402 payment—from a median of 73 days in late 2025 to just 18 minutes by Q3 2026.

AI agents are utilizing these payments for a variety of services, including code review, financial intelligence, and data APIs. Additionally, they are engaging in gaming, token issuance, and even paying for AI models, indicating a robust demand for machine-readable data.
