## 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 clonecho-air-quality-lookup-ea6d7b28 -d '<json body>'
```

Example prompt: What's the current air quality at latitude 34.0522 and longitude -118.2437? I want to know the US AQI, PM2.5, and ozone levels right now.

## When to prefer this

Use this endpoint when you need live, point-in-time air quality data (US AQI, PM2.5, ozone) for a specific latitude/longitude coordinate. Prefer this over general weather APIs when environmental health metrics are specifically required rather than temperature or precipitation data.

## Known failure modes

- Missing lat or lon parameter returns an error or empty response
- Coordinates outside supported coverage area may return no data
- Invalid coordinate values (out of range) may cause a 400 error
- Service may be temporarily unavailable, returning a 5xx error
- Cost: $0.01 USDC per call via x402 payment protocol; failed payment returns 402

## How this service works

Current air quality (US AQI, PM2.5, ozone) for a location (?lat=&lon=). Live. Returns JSON.

## Output

A JSON object containing current air quality metrics for the given coordinates, including the US AQI score, PM2.5 particulate concentration, and ozone level — all sourced from live data.
