# AgentRXI Air Quality Stations Finder

> AgentRXI Air Quality Stations Finder is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-15).

Find active air quality monitoring stations near a location 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 agentrxi-air-quality-stations-finder-a6f54e71
```

Example prompt: Find me all active air quality monitoring stations near Berlin that are currently measuring PM2.5, and show me up to 10 results with their coordinates and last reading time.

## When to prefer this

Use this endpoint when you need to discover which air quality monitoring stations are currently active and reporting near a specific geographic location or within a country, especially when you need metadata like operator, reference-grade status, and pollutant coverage before fetching actual readings. Prefer this over raw air quality data endpoints when the task is station discovery and network mapping rather than retrieving pollution measurements themselves.

## Known failure modes

- No stations found near the specified location or country — empty result set returned
- Invalid or unrecognized place name causing lookup failure
- Unsupported pollutant parameter code returns empty or error response
- Missing required query parameter (type, method) causes validation error
- Network or upstream data provider outage returns 5xx error
- Invalid country ISO code returns error or empty results

## 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

A list of active air quality monitoring stations matching the query, each containing station name, operator, reference-grade flag (boolean), geographic coordinates, distance from the query location, list of pollutants measured (e.g. pm25, no2, o3), and timestamp of the last reading.
