Voice API Pricing

$0.002 a minute. The network underneath comes free. Two lines on the bill: the API and the SIP trunk it rides. Both published, neither marked up, because the carrier and the API are one company. Every feature is a separate primitive at its own rate.

Public rate cards, side by side. The difference is structural: the carrier, the network, and the API are one company, so there is no markup on someone else's rate.
