AI Voice Calls
Outbound AI-powered phone calls (5-30 min)
Outbound AI voice calls powered by Bland.ai with real-time conversation. Assign a task prompt, the AI handles the call naturally (appointment confirmations, delivery notifications, surveys). Get real-time transcripts and recordings. Calls last 5-30 minutes. Works with Phone Numbers service — buy a dedicated number for caller-ID, then use it as your "from" number. Combine with Exa Search to research context before calling.

Phone Numbers
Dedicated US/CA numbers with 30-day lease
Wallet-owned dedicated US/CA phone numbers via Twilio. Buy a number ($5/month auto-renewing lease), use it as caller-ID for AI voice calls. Numbers are bound to your wallet — no Twilio account needed. List active numbers, renew or release on demand. Non-US numbers available but require Twilio KYC approval (1-5 business days).

Phone Lookup
Carrier identification and fraud detection
Carrier identification and fraud risk assessment for any phone number. Basic lookup returns carrier name and line type (mobile/landline/VoIP). Fraud check adds risk score, risk level, and fraud signal flags. Useful for verification workflows — check if a number is legit before making an AI call to it.

|---|---|---|---|
POST | /lookup | $0.011 | Carrier identification |
POST | /lookup/fraud | $0.055 | Fraud signals |
How to pay
Call any endpoint. Without a key you get HTTP 402 with the exact price in USDC; sign that quote with a Base or Solana wallet and repeat the request. With an account API key the same call is billed to your balance instead.
