# ForgeMesh Air Quality Index API

> ForgeMesh Air Quality Index API is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Returns current US AQI, PM2.5, PM10, ozone, and NO2 air quality readings for any latitude/longitude worldwide from a global air-quality model.

## Facts

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 forgemesh-air-quality-index-api-7ffaf5f2 -d '<json body>'
```

Example prompt: What's the current air quality index and PM2.5 level at latitude 29.76, longitude -95.36? I want to know if it's safe to go for a run outside.

## When to prefer this

Use this endpoint when you need real-time air quality data (AQI and key pollutants) for any global coordinate pair, especially for health advisories, travel planning, logistics routing, or smart-home air purifier automation. Prefer this over weather APIs that don't include pollutant breakdowns.

## Known failure modes

- Missing or invalid latitude/longitude returns a 400 or error response
- Coordinates outside supported geographic coverage may return null or empty pollutant values
- Model data may be delayed or unavailable for extremely remote locations
- Payment failure (402) if USDC balance is insufficient

## How this service works

Air quality index API by coordinates: current US AQI, PM2.5, PM10, ozone, and NO2 for any lat/lon worldwide from a global air-quality model. For health, travel, logistics, and smart-home agents.

## Output

Returns the current US AQI score along with individual pollutant readings for PM2.5, PM10, ozone, and NO2 for the specified geographic coordinates, sourced from a global air-quality model.
