Usage & Billing

AgentPhone uses pay-as-you-go billing. Every account starts with a $5.00 free credit — no credit card required. You pay only for what you use, and your balance is debited automatically as you make calls, send SMS, and maintain phone numbers.

Pricing

Voice calls are billed per second with a 1¢ minimum. Phone number fees are charged on provisioning and renew every 30 days.

Call recording add-on

Call recording is an optional add-on at $5.00/month (billed from your credit balance). When enabled, all voice calls are automatically recorded and the audio URL is included in call responses via the recordingUrl field.

Enable or disable recording from the Billing page in the dashboard. The fee is charged immediately on activation and renews every 30 days. If you cancel, recording stays active until the end of the current billing period. Existing recordings are preserved even after cancellation.

See Calls > Call recording for response field details.

Balance & auto-recharge

Your project maintains a dollar balance. Usage is debited in real time. When your balance drops below a threshold you set, AgentPhone can automatically charge your card on file to top up.

Configure auto-recharge from the Billing page in the dashboard:

• Threshold — recharge when balance falls below this amount
• Recharge amount — how much to add each time

If auto-recharge is not enabled and your balance runs low, you’ll receive an email notification. Phone numbers with unpaid renewals enter a 30-day grace period before being released.
