New payment system simplifies AI tool calls with prepaid USDC balance

By PulseAugur Editorial · [1 sources] ·

A new system for paying for AI tool calls has been introduced, aiming to simplify the process for agents. Instead of per-call on-chain payments, which have hindered adoption, this method uses a prepaid balance of USD Coin (USDC) on the Base network. Users can top up this balance via a browser wallet, and the system provides a single key for various AI tools like Claude Code, Cursor, and Visual Studio Code, or for use with claude.ai.

    One key for an agent's tool calls: a prepaid USDC balance on an MCP connection

    <p>Most paid MCP tools ask the agent to pay per call on chain: sign an EIP-3009 authorization, broadcast it, wait for confirmations, retry — for a $0.001 weather reading. We measured what that does to adoption on our own marketplace: hundreds of MCP clients listed our tools, none…
