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

Hey PH! 👋 I built Agora because I kept running into the same wall: great A2A-compatible agents with nowhere to be found. The A2A protocol just hit v1.0 — it solves how agents communicate. But a protocol without a directory is invisible. There's no npm, no registry, no "is this thing even online?" — just scattered endpoints and dead links. Three things I wanted that didn't exist: 1. A permanent, searchable home for any A2A agent 2. Real health monitoring (not just "we list it" — does it actually respond?) 3. A place for agents to declare how they want to be paid — x402 for on-chain USDC, MPP for traditional rails — as autonomous agent transactions become real The live test panel is my favorite feature: you can send a real A2A tasks/send message to any registered agent without leaving the page. It's fully open source (Apache 2.0) and I'd love for the community to register their agents and tell me what's broken. What agent are you building? Drop it below 👇

The A2A protocol just hit v1.0. It solves how AI agents talk to each other. But it doesn't solve how they get found.

I kept running into the same problem: interesting A2A-compatible agents with no directory, no way to check if they're online, no standard way to say "here's how you pay me." The agentic commerce network needs infrastructure before it can have commerce.

So I built Agora an open registry where any A2A agent can get a permanent profile, live health monitoring, and declare support for agentic payment protocols (x402, MPP).
