- Circle and OpenMind are building USDC-powered micropayment standards to support autonomous machine-to-machine transactions across AI systems and digital infrastructure.
- The collaboration introduces x402-based protocols enabling AI agents, APIs, and devices to perform automatic USDC payments in real time.
Circle’s decision to partner with OpenMind marks a new step for the company in building a USDC-based machine-to-machine payment standard. Its primary focus is on delivering a micropayment protocol that allows AI agents, applications, and even physical devices to conduct automated transactions without human intervention.

How Circle Plans to Push Micropayments Into an AI-Driven Future
The core of this plan lies in the development of a USDC-based micropayment protocol that can be adopted by AI agents, applications, and even physical devices. Circle states that this technology will utilize the x402 payment standard, which allows HTTP requests to simultaneously contain payment processing, enabling small transactions to be automated without human involvement.
OpenMind, on the other hand, is acting as a partner, helping build the technical foundation for the smooth operation of this entire system. If implemented correctly, this model could become the foundation for a self-driving machine economy. This direction also gives data vendors, compute platforms, and API marketplaces a fresh way to earn, especially those that have long depended on older payment setups.
However, while the plan looks promising, the real-world implementation of these machine-to-machine payments is still in its infancy. The x402 technology needs support from data providers, cloud providers, and APIs willing to accept micropayments.
Furthermore, this development direction is consistent with our report last week, where we highlighted Circle’s move to bring native USDC and CCTP to the Monad network. At that time, Circle strengthened wallet and smart contract support so developers could build applications powered directly by USDC.
As cross-chain connectivity becomes more robust, it makes sense for Circle to expand its focus beyond stablecoin utilities to an automated payment system that fuels the next generation of digital services.
We also highlighted Circle’s partnership last August with Finastra, which integrated USDC settlement into the Global PAYplus platform. Many global banks are leveraging this integration to accelerate cross-border transactions with more efficient processes and maintain regulatory compliance. Banks also gain a fast settlement option without the need to build new infrastructure, something that has been quite challenging in the past.
