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. $0.01 USDC x402 Base.
Output
A JSON object with an 'ok' boolean flag, a 'niche' field set to 'air_quality', and a 'result' object containing real-time air quality metrics including PM2.5, PM10, ozone concentrations, and the Air Quality Index (AQI) for the requested coordinates.
Example use cases
Outdoor exercise safety check
“Is the air quality good enough for a run right now at 34.0522 latitude, -118.2437 longitude? Give me the AQI and PM2.5 levels.”
ESG environmental compliance report
“Pull the current air quality data including PM2.5, PM10, ozone, and AQI for our factory site at 51.5074 latitude, -0.1278 longitude so I can include it in our ESG report.”
Health risk alert for insurance claim
“I need real-time air quality readings — AQI, PM2.5, and ozone — for the location at 29.7604 latitude, -95.3698 longitude to assess environmental health risk for a client claim.”
Technical details
Endpoint
POSThttps://air-quality.hergertsynthora.com/service?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, coordinate-based air quality data including AQI, PM2.5, PM10, and ozone for health, ESG, or insurance use cases. It is ideal for agent workflows that require environmental data at arbitrary global coordinates without a subscription, since it is a pay-per-call micropayment service using x402 on Base. Prefer this over general weather APIs when the specific output is air quality (not temperature or precipitation).
Side effects
- Missing or invalid latitude/longitude returns an error or empty result
- Coordinates outside supported coverage area may return null or incomplete data
- Payment failure (insufficient USDC balance) blocks the request
- Open-Meteo upstream outage may cause delayed or failed responses
- Malformed JSON body returns a 400-level error
