Illustrative agent-editor cost strip in the builder’s format.
Straight answers about cost.
It depends on the stack. The default stack runs about $0.062 a minute at the providers’ published rates, itemized by layer on every call.
Each provider’s published price list, kept in a versioned price book with the vendor page linked on every row. Rate changes get a new version, not a silent edit.
Not yet. Today you pay for usage, itemized by layer at the rates on this page. If that changes, it changes with notice and a new price-book version.
Yes. Every call records the price-book version, so any charge can be checked against its rate.
A dash means the number isn’t set yet. We show that plainly instead of guessing or showing a zero.
No plan price is published. Usage is billed per call at the itemized rates above. New accounts start with $5 of free credit, no card required.
Connected minutes on transcriber, voice, model, and carrier are metered separately and itemized on the receipt.
Each call has its own dashboard receipt, itemized like the bill above, with the price-book version that billed it.
It depends on call volume. See the worked examples above for 100, 500, and 2,000 minutes a month, at the default-stack rate — not a monthly plan, since none is published yet.
