Saylor Innovations Air Quality API
x402
Saylor Innovations Air Quality API is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).
Returns US and European AQI, per-pollutant breakdowns (PM2.5, PM10, NO2, SO2, CO, ozone), UV index, pollen counts, and 24-hour peak forecast for any lat/lon coordinate

How this service works
Air quality index by location - US and European AQI, dominant pollutant, per-pollutant AQI, PM2.5, PM10, ozone, NO2, SO2, CO, UV, pollen and the next 24 hours peak for any latitude and longitude
Output
A JSON object with US AQI value and category, European AQI, the dominant pollutant, individual pollutant concentrations in µg/m³ (PM2.5, PM10, NO2, SO2, CO, ozone), UV index, pollen grain count, a health note, a pollen note, the observation timestamp, the check timestamp, the data source, and a next-24-hour peak forecast summary for the given coordinates.
Example use cases
Outdoor run safety check
“I'm planning a run in Central Park this morning — can you check the air quality at latitude 40.7851, longitude -73.9683 and tell me the US AQI, what the dominant pollutant is, and what the peak will be over the next 24 hours?”
Asthma travel advisory
“My friend has asthma and is visiting Paris next to the Eiffel Tower at about latitude 48.858, longitude 2.294 — can you pull the European AQI, PM2.5 and ozone levels, and any health notes so they know if it's safe to be outside?”
Pollen season monitoring
“It's allergy season and I want to know the pollen count and UV index right now for my home coordinates — latitude 37.77, longitude -122.42 in San Francisco — plus whether air quality is expected to get worse in the next 24 hours.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/air/quality?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive air quality data — including both US and European AQI standards, individual pollutant concentrations, UV index, pollen counts, and a 24-hour forecast — all from a single call for any lat/lon on Earth. Prefer it over weather APIs that only include AQI as a side field, or over government APIs that are region-locked (US-only or EU-only). Especially useful when you need cross-standard AQI comparison or when building health advisories that require multiple environmental signals simultaneously.
Side effects
- Missing lat or lon parameters returns an error — both are required
- Invalid or out-of-range coordinate values may return null fields or an error
- No observational data available for remote or ocean coordinates — fields may return null
- Third-party data source unavailability may result in null values for some pollutants
- Rate limiting or payment failure returns a 402 or 4xx HTTP error
