Vapi Made Crystal Clear · chapter 3: Your first agent that answers the phone
the four artifacts of one finished call
2026-10-18
The transcript is the one everybody reads and the least informative of the four.
Below: the paragraph from the book that builds this idea, then the diagram itself (Figure 3.2), and a recap. About a minute of reading.
A call is the unit everything in this book is measured against, and a finished one hands you four artifacts. Most people read one of them, the transcript, and stop. The other three are where the answers live: the ended reason tells you what happened, the recording tells you how it felt, and the cost breakdown tells you what it charged. Figure 3.2 labels all four.
