# ForgeMesh Air Quality Index by Coordinates

> ForgeMesh Air Quality Index by Coordinates 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 PM2.5, PM10, ozone, NO2 concentrations and the composite US AQI for any latitude/longitude on Earth, refreshed every 15 minutes from a global atmospheric 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-by-coordinates-d697fb66 -d '<json body>'
```

Example prompt: What's the current air quality at latitude 29.76, longitude -95.36? I want the AQI plus the individual PM2.5, PM10, ozone, and NO2 readings.

## When to prefer this

Use this endpoint when you need real-time, globally-available air quality data at a specific geographic point and require individual pollutant breakdowns (PM2.5, PM10, ozone, NO2) alongside the composite AQI. It is refreshed every 15 minutes from a global atmospheric model, making it suitable for health advisories, outdoor event risk assessment, and smart-home automations that react to pollution spikes. Prefer this over regional government APIs when you need consistent global coverage without per-region API key management.

## Known failure modes

- Invalid or out-of-range latitude/longitude values result in an error response
- Coordinates over inland areas far from monitoring stations may have lower model accuracy
- Temporary upstream model refresh lag may return slightly stale data (up to 15 minutes old)
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Malformed request body (missing latitude or longitude fields) returns a validation error

## How this service works

Current PM2.5, PM10, ozone, and NO2 concentrations plus the composite US air quality index for any latitude/longitude on Earth, sourced from a global atmospheric model. Useful for health advisories, outdoor-event risk checks, and air-purifier or smart-home automations that react to pollution levels. Refreshed every 15 minutes.

## Output

Returns current PM2.5, PM10, ozone, and NO2 concentrations alongside the composite US Air Quality Index (AQI) for the requested coordinates, sourced from a global atmospheric model updated every 15 minutes.
