  • Call Transcripts — Search through recent call logs, retrieve call details natively, and pull raw voice-to-text transcripts or conversation metrics.
  • Persona Engineering — Ask your chat agent to build new Vapi assistants, update their system prompts, change its specific model, or mutate Voice IDs on the fly.
  • Squad Routing — List available telephony numbers, tools, and multi-agent squads natively to configure advanced conversational pathways.

List all our configured Voice assistants and their IDs.

You currently have 3 conversational Voice AI assistants configured in Vapi: 'Lead Qualification Bot' (ID: ba1-342x), 'Support Intake Matrix' (ID: cd3-99ab), and 'Internal Switchboard' (ID: 9fz-77qp). Do you want to see the system prompts behind any of these?

Get the details and full transcript for call ID 'vapi1234'.

I've retrieved the call log for 'vapi1234'. This was an outbound call that lasted 2 minutes and 15 seconds. **Summary:** The AI Assistant contacted John Doe about his recent warranty claim. John indicated he has already shipped the defective unit. The AI processed this information gracefully and closed the ticket conceptually. Here is a snippet of the transcript: *User:* 'Yeah I sent it out through FedEx yesterday.' *Assistant:* 'Perfect, thank you John! I have updated your claim status to incoming...'

Update assistant 'Bot Support' to change its `model.model` parameter to `gpt-4o-mini`.

Successfully updated the conversational model for 'Bot Support'. It has transitioned in Vapi engine logic and is now utilizing `gpt-4o-mini`. Its next active conversation will run purely on this adjusted backend structure.

Yes! Through the `createPhoneCallTool`, you can ask your agent: `Initiate a phone call to +15551234567 using our 'Sales Assistant' persona`. It will format the payload correctly and instruct Vapi to dial the human using the specified AI persona.
