- Merchants integrate in 5 minutes with just 5 lines of code
- Agents discover and pay endpoints without manual registration or configuration
- Transactions under $1 cost only 3% (minimum 0.5¢) making micropayments commercially viable

- Catches silent payment address or network changes that would otherwise go unnoticed
- Free connection with no sign-up, plus pay-per-call options for flexible scaling
- Works across multiple AI agent frameworks (Claude, Cursor, VS Code, Gemini, ChatGPT) via standardized MCP protocol
- Local agent signing tool keeps private keys on the user's machine, never uploaded to servers
