# Coinbase Says AI Agents Could Drive Demand for Sub-Cent Stablecoin Payments By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/27656 Published: 2026-10-07T23:08:13.000Z Updated: 2026-10-07T23:08:13.000Z Section: Technology > A Coinbase Institute analysis says software agents may need low-cost, pay-per-use transactions to access APIs, data and other digital services. A Coinbase Institute paper published Oct. 7 says artificial intelligence agents may drive demand for sub-cent stablecoin payments as software increasingly accesses digital services on users’ behalf. The analysis describes software agents that can retrieve information, compare options and complete transactions as a second customer of the internet. Such agents may make repeated requests during a single task, creating a need for frequent, low-value payments between software services. Traditional payment methods can make those transactions uneconomical because fixed fees, subscriptions and account-based billing may cost more than the API request or data access itself. A $0.01 payment, or one worth a fraction of a cent, requires a different cost structure from a conventional consumer purchase. Stablecoins on lower-cost blockchain networks could provide an alternative settlement method. The analysis presents this as a potential use case for crypto payments between software agents, not as evidence that high-frequency agent payments have already reached mass adoption. The x402 protocol uses the HTTP 402 “Payment Required” response to let a server specify payment terms before granting access to an API or another digital resource. The client submits payment information, which can be verified before access is provided. x402 uses USD Coin (USDC) amounts in six-decimal atomic units, with 10,000 units representing $0.01. Payment verification is supported on Base mainnet, identified as eip155:8453, with requirements that include the asset, payment amount and a maximum timeout. The system allows agents to pay for individual requests and use agent-owned wallets with programmable USDC spending limits. That structure could let software handle many small transactions without requiring a person to approve each payment manually. The analysis treats software that retrieves information, compares options and transacts for users as a new customer of the internet. The idea extends recent discussion of crypto and stablecoins as payment rails for interactions between AI agents, including [Coinbase CEO Brian Armstrong’s earlier comments on the use case](). The paper does not establish a completed rollout or a specific adoption timetable. Its central argument is that the growth of agent-driven digital services could make payment size, transaction fees and automated authorization more important parts of internet infrastructure. ## Links in this article - [Coinbase CEO Brian Armstrong’s earlier comments on the use case](https://www.tokenpost.com/news/technology/24165)
