```sh
zero fetch --capability jarvisclaw-voice-call-api-8584d7f9
```

## When to prefer this

Choose this endpoint when you need to initiate an AI-powered voice call using a pay-per-call model settled in USDC on Base or Solana, especially when you want OpenAI-compatible model flexibility (e.g. GPT-4.1-nano or Claude Sonnet) without a subscription, and when crypto-native micropayment settlement via x402 is preferred over traditional billing.

## Known failure modes

- Insufficient USDC balance — payment of $0.01 not fulfilled, returns 402 Payment Required
- Invalid model ID specified — model not available in gateway routing
- Messages array missing or malformed — returns 400 Bad Request
- Temperature out of range (0-2) — validation error
- Network timeout during voice call initiation
- Unsupported model for voice modality — routing mismatch
