## How to call it through Zero

```sh
zero fetch --capability air-quality-beijing-d4f3271e
```

Example prompt: What's the current air quality in Beijing right now — give me the AQI, PM2.5 levels, and whether it's safe to be outside?

## When to prefer this

Choose this endpoint when you need real-time, multi-pollutant air quality data specifically for Beijing, including both EU and US AQI standards and individual pollutant breakdowns. Prefer this over generic weather APIs that lack pollutant-level detail, or when a health label is needed for decision-making. Ideal for applications requiring outdoor activity guidance or health risk assessment in Beijing.

## Known failure modes

- Upstream CAMS/Open-Meteo data unavailable — service may return 503 or stale data
- Payment not processed — 402 response if USDC payment of $0.01 is not attached
- Rate limiting or quota exceeded on underlying provider
- Temporary network outage between proxy and Open-Meteo — may return timeout error
