## 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-dialogue-via-fal-ai-async-queue-c5a09aca -d '<json body>'
```

Example prompt: Can you turn this two-person dialogue script into audio using ElevenLabs v3 — Speaker A says 'Welcome to the show!' and Speaker B replies 'Thanks, great to be here!' — submitted as an async job so I can poll for the result?

## When to prefer this

Choose this endpoint when you need to synthesize multi-speaker dialogue audio using ElevenLabs' latest expressive v3 model and the generation may exceed real-time sync timeouts (~100s). Ideal for longer scripts, complex multi-turn conversations, or batch audio production pipelines where async polling is acceptable. Prefer over synchronous alternatives when output quality (ElevenLabs v3 expressiveness) matters more than latency.

## Known failure modes

- Invalid or missing text input returns a 422 validation error
- Queue timeout if the generation job takes too long on the backend
- Polling for a non-existent or expired request_id returns a 404
- Unsupported speaker configuration or voice parameters may cause a generation failure
- Dynamic pricing may cause payment authorization to fail if budget is insufficient

## How this service works

ElevenLabs v3 dialogue (dynamic pricing)

## Output

Returns a request_id immediately upon submission. The agent must poll the fal.ai queue status endpoint with the request_id to retrieve the final result, which includes a URL or binary payload of the synthesized dialogue audio file once generation is complete.
