## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-telephony-mcp-1ad78989 -d '<json body>'
```

Example prompt: Call the number +1-555-234-5678 and deliver this message: 'Your appointment is confirmed for tomorrow at 3pm — please press 1 to confirm or 2 to reschedule.'

## When to prefer this

Choose this endpoint when your AI agent needs to initiate real phone calls or voice/SMS communications as part of an automated workflow, especially within agentic pipelines that require reaching humans via phone rather than digital channels.

## Known failure modes

- Invalid or unreachable phone number returns an error response
- Insufficient USDC balance causes payment failure before call is placed
- Malformed data field causes request rejection
- Network or carrier issues may result in failed call delivery
- Rate limiting if too many calls are placed in quick succession
