## 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 synthetic-voice-curator-mcp-abb9a9f9 -d '<json body>'
```

Example prompt: Can you run my synthetic voice dataset through the voice curator to pick out the best-quality options and tell me which ones made the cut?

## When to prefer this

Choose this endpoint when you need to systematically curate, filter, or evaluate a set of synthetic voices rather than generating new ones. It is well-suited for pipelines where voice selection quality matters and manual review is not scalable.

## Known failure modes

- Ambiguous or unsupported voice format may return an empty result set
- Payment not received or insufficient USDC results in 402 Payment Required
- Timeout if input data is excessively large
- Service unavailable returns 503
