2s.io Air Quality by Coordinate
x402
2s.io Air Quality by Coordinate is a paid API for AI agents from 2s.io, paid per call via x402, $0.0012/call, status unknown (last checked 2026-09-14).
Returns current US AQI, European AQI, category label, and pollutant concentrations (PM2.5, PM10, O3, NO2, SO2, CO) for any lat/lon worldwide

How this service works
Current air quality for any coordinate worldwide. Pass lat + lon. Returns the US AQI (+ category Good/Moderate/Unhealthy…), the European AQI, and pollutant concentrations: PM2.5, PM10, ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide. Source: Open-Meteo / CAMS (keyless).
Output
A JSON object containing the current US AQI value and category (e.g. Good, Moderate, Unhealthy), the European AQI value, and individual pollutant concentrations for PM2.5, PM10, ozone (O3), nitrogen dioxide (NO2), sulphur dioxide (SO2), and carbon monoxide (CO) for the requested coordinate.
Example use cases
Example prompt
“What's the current air quality at latitude 40.7128, longitude -74.0060 — give me the US AQI category and the PM2.5 and ozone concentrations.”
Technical details
Endpoint
GEThttps://2s.io/api/weather/air-qualityWhen to prefer
Choose this endpoint when you need real-time air quality data (AQI + pollutant breakdown) for any arbitrary geographic coordinate worldwide, without requiring an API key. It provides both US and European AQI standards in a single call, making it ideal for international applications. Prefer over weather-only APIs when pollutant-level granularity (PM2.5, NO2, SO2, CO, O3) is required.
Side effects
- Missing lat or lon parameter returns a 400 bad request error
- Coordinates outside valid range (-90 to 90 lat, -180 to 180 lon) may return an error or empty result
- Upstream Open-Meteo/CAMS outage may cause 503 or empty data
- Payment failure (x402) returns 402 Payment Required if USDC balance is insufficient
