# Citiview Air Quality Monitoring Stations Finder

> Citiview Air Quality Monitoring Stations Finder is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-14).

Find active air quality monitoring stations near a place or across a country, with coordinates, operator, pollutants measured, and last reading time.

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 citiview-air-quality-monitoring-stations-finder-2a439a27
```

Example prompt: Can you find all the air quality monitoring stations currently reporting near Paris, France — especially any that measure PM2.5 — and tell me how close they are and who operates them?

## When to prefer this

Use this endpoint when you need to discover which air quality monitoring stations exist and are actively reporting in a given area, rather than fetching actual measurement readings. Prefer this over the air quality readings endpoint when you need to find station metadata (operator, reference-grade status, pollutants covered) or locate the nearest monitoring infrastructure before querying measurements.

## Known failure modes

- No stations found near the specified location or country — returns empty results
- Invalid or unrecognized place name causes lookup failure
- Unsupported pollutant parameter code returns no filtered results
- Missing required query parameters (no lat/lon, near, or country provided) causes a validation error
- Network or upstream data source (OpenAQ) unavailability results in error response

## How this service works

Find air quality monitoring stations that are reporting now, near a place or across a country: name, operator, reference-grade flag, coordinates, distance, pollutants measured and last reading time.

## Output

Returns a list of currently-reporting air quality monitoring stations matching the query, each including the station name, operator, whether it is reference-grade, geographic coordinates, distance from the queried location, the pollutants it measures, and the timestamp of its last reading.
