## 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 agify-name-age-estimator-a9d4c47d -d '<json body>'
```

Example prompt: What's the estimated age for someone named 'Jessica' — can you look that up using the name-based age estimator?

## When to prefer this

Use this endpoint when you need a quick demographic age estimate for a first name without requiring personal data. Ideal for enriching user profiles, personalizing content by inferred age group, or doing lightweight demographic analysis. Prefer this over heavier census APIs when simplicity and low cost matter.

## Known failure modes

- Missing 'name' parameter returns an error or empty result
- Very rare or unusual names may return null age due to insufficient data
- Non-alphabetic or numeric name inputs may produce no result
- Network or service unavailability returns HTTP error
- Payment failure (x402) prevents request from being fulfilled
