# Forgemesh Geo Air Quality API

> Forgemesh Geo Air Quality API is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

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

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-geo-air-quality-api-d1eb4052 -d '<json body>'
```

Example prompt: What's the current air quality at latitude 29.76, longitude -95.36 — give me the AQI, PM2.5, PM10, ozone, and NO2 levels.

## When to prefer this

Use this endpoint when you need real-time air quality data (AQI plus individual pollutants) for any arbitrary coordinate worldwide, especially for health advisories, outdoor event go/no-go decisions, smart-home air filtration automation, or travel planning. It covers global coordinates rather than city-name lookups and provides a standard US AQI alongside granular pollutant breakdowns.

## Known failure modes

- Missing or invalid latitude/longitude returns an error with no data
- Coordinates in remote or data-sparse regions may have lower model accuracy
- Payment failure (402) if USDC balance is insufficient
- Rate limits or network timeouts during high-load periods
- Stale data if cache has not refreshed within the 15-minute window

## How this service works

Air quality API: current US AQI plus PM2.5, PM10, ozone, and NO2 for any latitude/longitude worldwide, from a global air-quality model. Use for health advisories, travel planning, outdoor-event agents, and smart-home automation. Cached 15 minutes; attributed CC BY 4.0.

## Output

Returns the current US Air Quality Index (AQI) plus individual pollutant readings — PM2.5, PM10, ozone, and NO2 — for the specified coordinates, sourced from a global air-quality model and cached for up to 15 minutes.
