## 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 air-quality-index-lookup-pm2-5-pm10-o3-engedi-digi-life17-d14cbfb5
```

Example prompt: What's the current air quality in Delhi, India — specifically the PM2.5, PM10, and ozone levels?

## When to prefer this

Use this endpoint when you need quick, structured air quality data (PM2.5, PM10, O3) for a specific city by name, especially when integrating into an agent workflow that requires AQI as an input signal for health, travel, or outdoor activity decisions. It is lightweight and cheap ($0.01/call) compared to subscribing to a dedicated environmental API.

## Known failure modes

- City not found or unrecognized city name returns error or empty data
- Missing required 'city' query parameter returns validation error
- Data may be cached and not fully real-time (check 'cached' and 'last_updated' meta fields)
- Low confidence score in _meta indicates uncertain or stale underlying data
- Country code mismatch may cause ambiguous city resolution (e.g. multiple cities with same name)
