x402 on Arkham
August 5, 2026
We’ve added support for Coinbase’s x402 Standard, developed by Coinbase, and governed by the Linux Foundation to the Arkham API, enabling AI agents to pay for Arkham API usage with USDC directly at request time. Here’s how you can use the Arkham API for trading with AI Agents:
Using Coinbase Agentic Wallet and the Arkham API, traders can ask an AI agent to track the onchain movements of top token holders, identify whale accumulation or selling, and analyze wallet flows in real time.
Agents can monitor large transactions, follow smart money across wallets, and surface emerging buying or selling activity without traders having to manually dig through the blockchain.
This makes it possible to turn real-time onchain data into actionable trading intelligence, with agents autonomously accessing the data they need when they need it.
“Arkham is exactly the kind of high-value data API x402 was built for. By leveraging the CDP Facilitator and USDC on Base, Arkham is making production-grade onchain intelligence instantly accessible to AI agents, at request time. This is a major step toward an internet where agents can autonomously discover, purchase, and use the data they need.”- Kevin Leffew, AI GTM Lead @ Coinbase
