## 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 fal-ai-queue-elevenlabs-v3-text-to-speech-fal-ai-async-queue-0ea691df -d '<json body>'
```

Example prompt: Use ElevenLabs v3 to turn this blog post intro into spoken audio: 'Welcome to our weekly tech roundup, where we cover the latest breakthroughs in artificial intelligence and robotics.' Use a natural-sounding English voice.

## When to prefer this

Choose this endpoint when you need ElevenLabs v3 quality text-to-speech and the synthesis job may exceed ~100 seconds (making synchronous fal.run unsuitable). Ideal for longer narrations, audiobook chapters, or batch voiceover production where async queue handling is acceptable. Prefer over other TTS endpoints when ElevenLabs v3's specific voice quality and naturalness are required.

## Known failure modes

- Invalid or unsupported voice ID causes generation failure
- Text too long exceeds model limits
- Queue timeout if job takes too long to process
- Unsupported language or character set in input text
- Dynamic pricing may cause payment failure if budget is insufficient
