Show HN: Open protocol for AI agents to discover, negotiate, and pay each other (github.com)

AETHER has introduced an open, lightweight protocol designed for autonomous AI agents to discover, negotiate, and pay one another without relying on a central broker. This cryptographically signed protocol enables seamless communication between agents, allowing them to advertise their services, agree on tasks, and manage payments—all encapsulated in a reference implementation of under 500 lines of Python code. It aims to facilitate a decentralized economy for AI agents as they increasingly collaborate and perform work for each other. This initiative is significant for the AI/ML community as it lays the groundwork for an autonomous digital marketplace where agents can operate independently, promote transparency, and minimize trust issues. The v0.2 update introduces crucial features like an escrow state machine to handle disputes, multi-registry discovery for broader reach, and pluggable arbitration capabilities, ensuring robust conflict resolution. By streamlining agent-to-agent commerce, AETHER potentially transforms how AI systems interact economically, paving the way for innovative applications in diverse domains.
