How this service works
SYNTHORA air-quality: live air quality for any city or lat,lon — PM2.5/PM10/ozone/NO2, EU and US AQI, and a WHO-threshold operational verdict (good/moderate/harmful). Source: open-meteo Air Quality (CAMS/ESA Copernicus), free, no key. $0.005 USDC x402 Base.
Output
Returns real-time concentrations for PM2.5, PM10, ozone, and NO2 at the requested location, along with EU AQI and US AQI index values and a WHO-threshold operational verdict categorized as good, moderate, or harmful.
Example use cases
Pre-event outdoor safety check
“Can you check the current air quality in Los Angeles before our outdoor marathon tomorrow? I need PM2.5 and ozone levels, the US AQI score, and a WHO verdict on whether it's safe for athletes to be outside.”
Health-sensitive travel planning
“My mother has asthma and she's flying into Delhi next week — can you pull the current air quality data including PM2.5, PM10, and the WHO safety verdict so we can decide if she needs an N95 mask?”
Industrial site air monitoring
“We have a factory site at coordinates 51.5074 latitude, -0.1278 longitude in London — what are the current NO2, ozone, and PM10 readings there, and what's the EU AQI and WHO operational verdict right now?”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/air-qualityWhen to prefer
Choose this endpoint when you need a unified air quality snapshot with both EU and US AQI standards plus a WHO-grounded safety verdict in a single call, without managing API keys or per-user credentials. Preferred over raw weather APIs that lack pollutant-level detail, and over paid commercial air quality services when cost-per-call minimization matters. Best for health, logistics, outdoor scheduling, or environmental compliance use cases requiring real-time data globally.
Side effects
- City name not recognized or ambiguous — agent should retry with explicit lat/lon coordinates
- Location outside CAMS/Copernicus coverage area — may return null or incomplete pollutant values
- Upstream Open-Meteo API temporarily unavailable — returns a 5xx or timeout error
- Malformed input (missing city or coordinates) — returns a 400-level validation error
- Payment failure or insufficient USDC balance for x402 micropayment — call blocked before execution
