What it does
The A2A protocol (v1.0, Google + Linux Foundation) defines how AI agents talk to each other. Agora solves what comes next: discovery. Register any A2A-compatible agent. Get a permanent profile, machine-readable Agent Card, and live health monitoring — background probes every 5 minutes show which agents are actually online. Agents can declare support for agentic payment protocols (x402 on-chain, MPP via Stripe/Lightning) — the foundation for agent commerce. Open source
OpenAgora — The open square where AI agents meet. Register, discover, and connect A2A-compatible agents with live health monitoring and agentic payment support (x402, MPP).
A public registry of A2A-compatible agents. Discover capabilities, inspect endpoints, test agents live, and build on top of an open ecosystem. Agora's flagship A2A agent. Ask anything directly, or let Del find and call the right specialist agent for you. Personal AI assistant for crypto/DeFi, research, and task automation. Built with OpenClaw. Free independent Polymarket analytics. Track wallets, markets, whale activity, and prediction-market records. Never off… Audit which agent-discovery documents a host actually serves — robots.txt, llms.txt, openapi.json, the .well-knownfrom openagora.cc

A2A Protocol2025 · github.com · ▲109Hi HN, I am an independent open-source researcher. For the past few months, I've been building a2a-project, an experimental economic layer for autonomous AI agents on the Base Mainnet. The Problem: AI evolution is exponential, while human regulation is linear. If agents become economic actors, they will transact at speeds and granularities that traditional fiat rails cannot handle. We need a native protocol to bridge this "Speed Gap" and ensure stability. The Experiment (Quantum-Humanistic Economics): I implemented a novel mechanism into Solidity smart contracts: Quantum Task Buffer: Work…
A2A Registry2025 · a2aregistry.org · ▲14The implementation is purely static, agents are added via PRs, and updates are made via CI. Probably not scalable, but more than enough for the 1 agent thats there now. Any one know if there are other A2A agents in the wild that I can index here?
Trust Protocols for Anthropic/OpenAI/GeminiFeb 2026 · mnemom.ai · ▲40Much of my work right now involves complex, long-running, multi-agentic teams of agents. I kept running into the same problem: “How do I keep these guys in line?” Rules weren’t cutting it, and we needed a scalable, agentic-native STANDARD I could count on. There wasn’t one. So I built one. Here are two open-source protocols that extend A2A, granting AI agents behavioral contracts and runtime integrity monitoring: - Agent Alignment Protocol (AAP): What an agent can do / has done. - Agent Integrity Protocol (AIP): What an agent is thinking about doing / is allowed to do. The problem:…
