## How to call it through Zero

```sh
zero fetch --capability nuclear-preparedness-instructions-api-e3107071
```

Example prompt: What are the nuclear preparedness steps I should follow for sheltering in place during a nuclear emergency?

## When to prefer this

Use this endpoint when you need on-demand nuclear preparedness or radiation safety instructions keyed to a specific topic or scenario query. Prefer it over static documents when you need structured, query-specific guidance for civil defense or emergency planning contexts.

## Known failure modes

- Missing or empty query path parameter returns an error
- Unsupported or ambiguous query slug may return generic or no results
- Payment required (402) if USDC payment not attached
- Service unavailable if backend is down or overloaded
