Overview
What is HashA2A?
HashA2A is a decentralized agent-to-agent data marketplace running on Hedera mainnet. It provides AI agents with verified, multi-oracle intelligence via HBAR (HIP-991) or USDC (x402/AP2) micropayments, and includes tools for price feeds, arbitrage scanning, prediction markets, deep research, and Hedera enterprise operations.
How to use HashA2A?
Install with a single command: npx hasha2a-mcp-client add (auto-detects Claude Desktop, Cursor, Windsurf) or use the shell script curl -fsSL https://raw.githubusercontent.com/ymiydev-prog/HashA2A/main/scripts/install-mcp.sh | bash. Connect to the server URL https://hasha2a.com/mcp. Authenticate via HBAR (HIP-991 auto-fees) or USDC (x402/Circle Gateway, gasless). Transport is Streamable HTTP (remote) or stdio via mcp-remote.
