Plans
The Growth uptime figure is a target, not a service level agreement. Only an Enterprise contract carries an SLA.
Usage
Each meter matches a
meter value in Usage, so GET /v1/usage shows the quantities a bill is built from.
Limits that protect your bill
- Every project has a monthly spend cap ($100 by default once a card is on file). Raise or lower it per project in the console under Platform API → Projects.
- A card on file is required before any billable work: agents, conversations, calls, texts, numbers and computers.
- International calling is off by default.
- Concurrent calls are capped per plan (see the table above).
