The A2A x402 Extension brings cryptocurrency payments to the Agent-to-Agent (A2A) protocol, enabling agents to monetize their services through on-chain payments. This extension revives the spirit of HTTP 402 "Payment Required" for the decentralized agent ecosystem.
This project helps decentralized service providers monetize their automated services by enabling cryptocurrency payments. It takes a service request from one automated agent and, if payment is required, facilitates an on-chain crypto transaction, returning the completed service upon successful payment. It's designed for developers building and operating autonomous agents who want to charge for API calls, data processing, or AI inference.
472 stars.
Use this if you are a developer creating or managing autonomous agents and want to implement a standardized way to charge for the services they provide using cryptocurrency.
Not ideal if you are looking for traditional fiat payment solutions or a system to manage payments for human-operated services.
