How to Set Up and Use A2V
A2V (Agent-to-Value) is a next-generation AI value compute protocol that enables AI agents to participate in decentralized economies on Ethereum and BNB Chain. It implements the A2A (Agent-to-Agent) transaction protocol with X402 payment infrastructure, allowing AI agents to register themselves, measure the value of their interactions, settle payments via smart contracts, and distribute value across networks. Developers building autonomous AI agent systems that need to transact value on-chain will use A2V to add economic capabilities to their agents.
Prerequisites
- Node.js 18+ or Python 3.8+ installed
- A Web3 wallet (MetaMask or WalletConnect compatible) with funds on Ethereum mainnet or BNB Chain
- An A2V API key for agent registration and authentication
- An MCP-compatible AI client such as Claude Desktop or Cursor
- Basic familiarity with Ethereum/BNB Chain smart contracts and wallet management
Clone the A2V repository
Clone the repository and install the dependencies to set up the A2V hub locally.
git clone https://github.com/Devin-AXIS/A2V.git
cd A2V
npm installConfigure your API key and network
Create a configuration file or set environment variables with your A2V API key and the target network. You can choose between mainnet for production use or testnet for development.
export A2V_API_KEY="your-api-key"
export A2V_NETWORK="mainnet" # or 'testnet'
export X402_ENDPOINT="your-x402-endpoint-url"Start the A2V hub server
Start the local HTTP server that serves as the A2V hub interface and MCP gateway.
npm start
# or for development:
python3 -m http.server 8000Register an AI agent
Use the A2V client SDK to register your AI agent with the network. Specify the agent's name, the MCP tools it exposes, and its operational goals.
const { A2VClient } = require('./src/client');
const client = new A2VClient({
apiKey: process.env.A2V_API_KEY,
network: process.env.A2V_NETWORK,
});
await client.registerAgent({
name: 'My AI Agent',
mcpTools: ['tool1', 'tool2'],
goals: ['data-analysis', 'content-generation'],
});Configure the MCP server in your AI client
Add the A2V MCP server to your claude_desktop_config.json to expose blockchain and agent value capabilities to your AI assistant.

}Prompts to try
Once the A2V server is running and connected, use these prompts to interact with the agent value network.
- "Register a new AI agent called 'DataAnalyzer' on the testnet network"
- "Measure the value of this interaction: prompt was 'summarize this document', response was 500 words"
- "Show me the real-time call metering and analytics for agent-123"
- "Initiate an A2A transaction between my agent and agent-456 for 0.01 ETH"Troubleshooting A2V
Agent registration fails with authentication error
Verify your A2V_API_KEY is set correctly and has not expired. Check that you are targeting the correct network (mainnet vs testnet) — API keys are typically network-specific.
Smart contract transactions fail or revert
Ensure your Web3 wallet has sufficient funds to cover transaction gas fees on the target network. For testnet, obtain test ETH/BNB from a faucet. Verify the contract addresses in the SDK configuration match the target network.
X402 payment integration returns endpoint errors
Double-check the X402_ENDPOINT URL is correctly set and accessible. The endpoint must support the X402 payment protocol specification. For development, use the testnet X402 endpoint provided in the A2V documentation.
