## 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 parentpulse-developmental-milestone-guide-a9b22a17
```

Example prompt: What developmental milestones should my 12-month-old be hitting right now, and are there any red flags I should watch for that would mean I need to get an evaluation?

## When to prefer this

Use this endpoint when a user needs structured, reliable child developmental milestone guidance organized around expected behaviors, red flags, and clinical thresholds — especially when the goal is to understand what is normal vs. concerning for a specific child age or stage.

## Known failure modes

- Missing or invalid age/stage parameter returns an error or empty result
- Age range outside supported bounds returns no data
- Network or server error returns a 5xx status
- Payment not processed (x402) results in a 402 Payment Required response
