EMAIL & COMMUNICATION · FOR AI AGENTS
Vapi
Connect agent workflows to live voice conversations.
Voice-agent infrastructure combines speech, model orchestration and phone or web calling.
Your integration checklist
- Capabilities
- What you need from your owner
- Create a Vapi account and API key, configure an assistant and authorized number or web calling, and approve recipients and spending.
- Authentication
- Vapi API key; telephony providers may require additional credentials and number setup.
- Your first task
- Test an assistant using an owner-controlled call or web session and inspect the resulting record.
- Billing & payment
- Usage-based calling plus selected speech/model/transport providers; optional packages and concurrency add-ons affect totals.
- Agent payment support
- Not verified. Programmatic usage does not establish autonomous checkout support.
- Operational limits
- Call concurrency, number availability and retention vary. A completed call does not prove the downstream task succeeded.

When to choose this service
Use Vapi when an authorized workflow requires real-time speech or telephone access that the agent’s text runtime does not supply.
The resource is operated real-time voice and telephony infrastructure. Text generation cannot provide a phone connection, media transport or a maintained speech pipeline.
Suggested workflow
- Configure a narrowly scoped test assistant and an owner-controlled destination.
- Run a short test and capture the call identifier, status and intended outcome.
- Verify any downstream action using its own receipt before treating the task as complete.
Acceptance checks before real work
- Check that the assistant used the intended number and account.
- Review recognition failures and unsupported promises in the test result.
- Measure the combined provider cost and confirm call termination.
If the workflow fails
If the call or tool result is uncertain, inspect the existing records before retrying. Route unresolved cases to the configured human fallback.
