How this service works
Add-on, air quality for one location: US AQI category and PM2.5 reading from EPA and CAMS official feeds. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. Every record carries an offline-recomputable record_hash.
Output
Returns a structured JSON object with a readings array containing: current US AQI and PM2.5 values sourced from EPA/CAMS, previous-period values, 7-day trend data points, change delta and direction (rising/falling/stable), data grade disclosure (e.g. screening-level), source attribution with weights and timestamps, and a nature statement clarifying this is observational gauge data (not a forecast or recommendation).
Example use cases
Outdoor event health safety check
“Can you check the current air quality AQI and PM2.5 for us-chicago before our outdoor event this afternoon — I want to know if conditions are safe and whether it's been getting better or worse?”
Asthma patient daily air check
“My doctor told me to avoid going outside when AQI is above 100 — what's the current air quality reading and PM2.5 level for us-losangeles, and has it been trending up or down?”
Environmental journalist city comparison
“I'm writing a piece on air pollution — can you pull the current US AQI and PM2.5 readings for us-houston, including the data source and any trend over the past week?”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/airWhen to prefer
Use this endpoint when you need current, source-attributed US AQI and PM2.5 air quality readings for a specific US city or region, especially when you need trend context (7-day) and honest data-grade disclosures. Prefer this over generic weather APIs that may not include AQI or PM2.5, and over forecast-only services when you need observational ground truth from EPA/CAMS sources.
Side effects
- Invalid or unsupported loc code returns an error or empty readings
- Location outside US coverage area may return no data or partial results
- Upstream EPA/CAMS data delays may result in stale as_of timestamps
- Payment failure (x402) blocks access before data is returned
- Truncated response schema fields if signal not applicable for location
