How this service works
Real-time US AQI and pollutant readings for any lat/lon. Returns current AQI with category label (Good/Moderate/Unhealthy/Hazardous), PM2.5, PM10, nitrogen dioxide, ozone, carbon monoxide, dust levels, and UV index. Data from CAMS (Copernicus Atmosphere Monitoring Service), updated hourly. Use for health advisories, outdoor event planning, environment-sensitive routing, or regulatory compliance checks.
Output
Returns current air quality data for the specified coordinates, likely including AQI (Air Quality Index) score, pollutant levels, and health categorization for the location.
Example use cases
Example prompt
“What's the current air quality like at latitude 40.71, longitude -74.01 in New York City — is it safe to go for a run outside?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/air-qualityWhen to prefer
Use this endpoint when you need real-time air quality data for any geographic coordinate worldwide without requiring API keys or account setup, and when your agent can pay micro-amounts of USDC on Base mainnet via x402. Ideal for autonomous agents needing environmental context at a specific location.
Side effects
- Missing required lat or lon parameters — returns 400 or validation error
- Coordinates out of valid range (lat > 90, lon > 180) — schema validation failure
- Payment failure or insufficient USDC balance — 402 Payment Required response
- No air quality data available for remote or ocean coordinates — may return empty or error
- Network timeout from upstream air quality data provider
