## 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 oneshotagent-ai-voice-call-d6dbae59 -d '<json body>'
```

Example prompt: Call +1-415-555-0192 and let them know that the delivery has been rescheduled for Thursday — the objective is to confirm they received the update, and you can tell them I'm the sender if they ask.

## When to prefer this

Choose this endpoint when you need an AI agent to autonomously place and conduct an outbound voice call to a real phone number with a defined goal and background context. It is ideal for automating follow-ups, notifications, information gathering, or task execution by phone, especially when paired with sibling endpoints like email sending and LinkedIn enrichment for multi-channel outreach workflows.

## Known failure modes

- Invalid or unreachable phone number — call fails to connect
- Missing required fields (phone_number, objective, or context) — request rejected
- Payment failure — x402 payment of $0.001 USDC not processed
- Call recipient does not answer — voicemail or no response
- Objective too complex for a single short call — partial completion
- Rate limiting or service unavailability — 429 or 503 response
