How do I connect to A2A agents?

You can connect to A2A agents using the Python client library: 'pip install a2a-registry-client'. The registry provides agent URLs, capabilities, and integration examples for each agent.

What is the A2A Protocol?

The A2A (Agent-to-Agent) Protocol is a standardized communication protocol that enables AI agents to interact with each other seamlessly. It defines how agents expose their capabilities, handle requests, and maintain interoperability.

Are the agents in A2A Registry free to use?

Most agents in the registry are free for demonstration and testing purposes. Each agent has its own pricing model detailed in its specifications. The registry itself and the Python client are completely free and open source.

A2A Protocol Agent Registry

The official directory of live, hosted AI agents compliant with the Agent2Agent (A2A) Protocol.

What is A2A Registry?

A2A Registry is a community-driven, open-source directory of production-ready AI agents that implement the A2A (Agent-to-Agent) Protocol. Unlike other agent directories that list code repositories, we exclusively index live, hosted agents with verified capabilities.

Key Features

A2A Protocol Compliant: All agents verified via .well-known/agent.json
Live & Hosted: Only production-ready, actively hosted agents
Python SDK: Easy integration with pip install a2a-registry-client
MCP Support: Model Context Protocol integration
Open Source: Git-as-database model on GitHub
15+ Verified Agents: Growing collection of production agents

Quick Start

Install: pip install a2a-registry-client
Discover: Browse agents at a2aregistry.org
Connect: Use the Python SDK to integrate agents
Verify: All agents are A2A Protocol compliant

Why A2A Registry?

The A2A Protocol enables standardized communication between AI agents, allowing them to discover, connect, and collaborate across different platforms. Our registry solves the critical agent discovery problem by providing:

Verified agent capabilities and endpoints
Live status monitoring
Easy integration via Python SDK
Open, community-driven ecosystem

For Developers

Submit your A2A Protocol compliant agent to the registry via GitHub pull request. All agents must:

Implement the A2A Protocol specification
Serve a valid /.well-known/agent.json endpoint
Be live and publicly accessible
Include accurate capability declarations
