Coinbase introduces x402 batch settlement. Source: x402.org X402 is an open protocol based on the HTTP 402 “Payment Required” status code to support machine-to-machine payments. Coinbase said the protocol processed over 169 million payments across 590,000 buyers and over 100,000 sellers in its first year.

AI agents using batch settlement will be able to accept any Ethereum-native ERC-20 tokens, not just stablecoins. The feature is currently available in TypeScript and Go, with a Python implementation coming soon. In the documented flow, the buyer opens or tops up a channel by depositing ERC-20 tokens into escrow. Each paid request includes a signed cumulative voucher, and the seller’s channel manager later claims vouchers from many channels in a single transaction before sweeping funds to the receiver.

On Monday, stablecoin issuer Circle launched a suite of tools enabling AI agents to use wallets, discover services and make programmable payments with USDC, Cointelegraph reported. On Friday, Aptos Foundation and Aptos Labs committed $50 million to Aptos development, with a particular focus on AI agent infrastructure and research, including AI-powered onchain order book and perpetual exchange Decibel and decentralized storage protocol Shelby.
