Example use cases
Outdoor exercise safety check
“Is it safe to go for a run outside in Portland, Oregon right now? Tell me the AQI, health band, and PM2.5 level.”

Technical details
Endpoint
POSThttps://twin.unykorn.org/geo/air-quality?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, US-AQI-standard air quality data including multiple pollutants (PM2.5, PM10, ozone, NO2) and UV index in a single call. It accepts either coordinates or a place name, making it convenient for both programmatic and natural-language-driven workflows. Prefer it over general weather APIs that omit detailed pollutant breakdowns or UV data.
Side effects
- Unknown or ambiguous place name returns an error or empty result
- Coordinates outside valid range (-90 to 90 lat, -180 to 180 lon) rejected with validation error
- Data unavailable for remote or sparsely monitored locations
- Payment failure (insufficient USDC balance) results in 402 rejection
- Network timeout if upstream air quality data source is unavailable
