# Rotary Agency Open-Meteo Air Quality API

> Rotary Agency Open-Meteo Air Quality API is a paid API for AI agents from rotaryagency.uk, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Fetches current and forecast air quality data (pollutant concentrations, AQI indices) for a given location via a proxied Open-Meteo Air Quality endpoint.

## Facts

- Endpoint: GET https://rotaryagency.uk/api/free/open-meteo-airquality?utm_source=zero.xyz
- Price: $0.002/call

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 rotary-agency-open-meteo-air-quality-api-fc782d58
```

Example prompt: What's the current air quality like in Berlin right now — give me PM2.5, PM10, and the European AQI for the next 24 hours.

## When to prefer this

Choose this endpoint when you need free-tier air quality data without setting up your own Open-Meteo integration, and are comfortable paying $0.002 per call via x402 micropayment. It is ideal for agents needing on-demand AQI and pollutant data by GPS coordinates without API key management. Prefer direct Open-Meteo if you need zero cost or high request volumes.

## Known failure modes

- Missing or invalid latitude/longitude parameters returns an error or empty response
- Coordinates outside supported geographic coverage return no data
- Requesting unsupported hourly variables returns an error from upstream Open-Meteo
- Rate limit or payment failure at $0.002/call boundary blocks the request
- Upstream Open-Meteo service outage results in a proxy error response
