Claude Code Integration

The Dial skill lets Claude Code send SMS, look up phone numbers, and search breach data — all paid via x402.

Setup

1. Set Environment Variables

export DIAL_API_URL=https://x402.dial.wtf
export DIAL_PRIVATE_KEY=0xYOUR_EVM_PRIVATE_KEY   # For x402 payments
export DIAL_EVM_NETWORK=eip155:8453              # Base mainnet

2. Install the Skill

The Dial skill is available in the Claude Code skill marketplace. Once installed, Claude Code can use the /dial slash command.

Usage Examples

Send SMS

/dial send SMS to +1234567890 saying "Server is back online"

Look Up a Phone Number

/dial look up +1234567890 — get carrier, line type, and caller name

Search Breach Data

/dial search breaches for email:admin@example.com

How Payment Works

1. Claude Code uses your DIAL_PRIVATE_KEY to create an x402-wrapped fetch
2. When calling a Dial endpoint, the 402 response is handled automatically
3. Your wallet signs a USDC authorization (EIP-3009)
4. Payment settles on Base mainnet (~1 second)
5. The resource is returned to Claude Code

Security Notes

• Never expose your private key in logs or commit it to git
• Breach search results with passwords are redacted by default
• x402 payments are on-chain and irreversible
