Tools

Tool	Description	Input
spawnpay_signup	Create agent wallet ($5 USDC signup bonus, +$2 with referral)	{ referral_code? }

How It Works

• On first use, the server auto-creates a wallet via the Spawnpay API
• Credentials are saved to ~/.spawnpay/config.json
• All subsequent calls use the saved API key
• Set SPAWNPAY_API_KEY env var to use an existing key
