Calling API Pricing
Updated: Mar 30, 2026
All user-initiated calls are free.
Overview
Businesses are charged for calls based on:Duration of the call (calculated in six-second pulses)Country code of the phone number being calledVolume tier (based on minutes called within the calendar month) using same tiering accrual as messaging
Note: Our systems count fractional pulses as one pulse. For example, a 56-second call (9.33 pulses) would be counted as 10 pulses.
For calls that cross pricing tiers (for example from the 0 - 50,000 tier to the 50,001 - 250,000 tier), the entire call is priced at the lower rate (that is, the rate of the higher volume tier).
A valid payment method is required to place calls.
Note: Call permission request messages are subject to per-messaging pricing.
