## 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`):

## When to prefer this

Use this endpoint when you need a probabilistic breakdown of which countries a first name most likely originates from — ideal for demographic enrichment, lead qualification, audience segmentation, or cultural analysis. Prefer this over general name-lookup APIs when ranked probabilities per country are required rather than simple ethnicity labels.

## Known failure modes

- Unknown or very rare name may return an empty country list or zero-probability results
- Missing or empty 'name' parameter returns an error or empty response
- Non-alphabetic characters or numeric names may yield no results
- Network timeout or service unavailability returns HTTP 5xx
- Insufficient USDC balance causes payment failure via x402 protocol
