- Circle’s wallets work with the X402 protocol for automated on-chain payments.
- This system allows AI agents to pay for API services using USDC without human help.
- This creates a new usage monetization model for developers and online services.
Circle Internet Financial has announced a new integration that will allow artificial intelligence agents to autonomously pay for online services. The development, announced on September 12, will combine the company’s wallet infrastructure with new payment protocols to promote automated trading using USD coins USDC $1.00 24-hour volatility: 0.0% Market Cap: $73.18 b Vol. 24H: $17.60 b .
According to Company Blog PostsThe system is built on Coinbase’s X402 protocol. This is an open standard that reactivates long-term HTTP 402 “Payment Request” status codes. This technology enables web services Request an on-chain payment Open new possibilities for API monetization before satisfying your data request.
The new model allows AI agents to complete transactions without human intervention. For example, agents that require wallet risk reports from paywalled APIs can automatically pay a small USDC fee to receive data, streamlining the entire process into one program flow.
New model of machine-to-machine commerce
This integration paves the way for new usage business models for developers and online platforms. Instead of relying on traditional subscriptions, services can now charge small amounts of individual API calls, making microtransactions a more viable option for monetizing digital resources.
The system utilizes Circle’s developer-controlled wallet, managed via APIs and protected by multi-party calculation (MPC) technology, and protects private keys. This allows AI agents to manage funds and allow payments without directly processing sensitive credentials.
To demonstrate functionality, Circle Langchain Framework and Openai’s GPT-4O mini model. In the demonstration, the agent successfully created a wallet, provided funds using a testnet faucet, and paid payments for risk profile reports from third-party services.
The fusion of AI agents with autonomous payment capabilities illustrates an important step towards a more sophisticated machine-to-machine economy. This allows the software to not only process information, but also participate in economic transactions, reflecting the company’s broader push Expanding USDC adoption.
