# AgentsToolsHub Live Air Quality

> AgentsToolsHub Live Air Quality is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-17).

Returns live air quality data for a city or coordinates, including US AQI, European AQI, PM2.5, PM10, ozone, NO2, SO2, and CO concentrations from Open-Meteo CAMS models.

## Facts

- Endpoint: GET https://agentstoolshub.com/api/v1/live/air-quality?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentstoolshub-live-air-quality-d7f028a2
```

Example prompt: What's the current air quality in San Francisco — give me the US AQI, PM2.5, and ozone levels?

## When to prefer this

Choose this endpoint when you need current, multi-pollutant air quality data (US AQI + European AQI + PM2.5/PM10/ozone/NO2/SO2/CO) for any city or coordinates without managing an API key. Prefer it over recalling training data or using weather APIs that omit air quality. The 30-minute cache makes it suitable for near-real-time checks rather than second-by-second monitoring.

## Known failure modes

- Unrecognized city name returns an error or empty result — use lat/lon instead
- Missing both city and lat/lon parameters causes a validation error
- Coordinates outside supported geographic coverage may return null pollutant values
- Service may return cached data up to 30 minutes old, not truly real-time
- Rate limits or payment failure (x402) will block the request

## How this service works

Live air quality by city or coordinates from Open-Meteo's CAMS models: US AQI and European AQI with PM2.5, PM10, ozone, NO2, SO2 and CO concentrations. No API key, cached 30 minutes — the air-quality check agents should run instead of recalling stale numbers. Use this when an agent needs to uS + European AQI, PM2.5 and ozone by city.

## Output

Returns current US AQI and European AQI index values along with individual pollutant concentrations (PM2.5, PM10, ozone, NO2, SO2, CO) for the requested city or geographic coordinates. Data is sourced from Open-Meteo CAMS atmospheric models and cached for 30 minutes.
