How this service works

Current air quality index (AQI) by US ZIP code -- PM2.5, ozone readings, category (Good/Moderate/Unhealthy), dominant pollutant, and outdoor-activity decision guidance. e.g. GET /api/air-quality/20002

Output

Returns overall AQI score and category (e.g. Good/Moderate/Unhealthy), individual readings for PM2.5 and ozone each with their own AQI and category, the dominant pollutant, a risk level (low/moderate/high), whether a mask is recommended, and a plain-English outdoor activity guidance summary. Data is sourced from the EPA AirNow API.

Example use cases

Example prompt

“What's the air quality like right now in ZIP code 20002 — is it safe to go for a run outside, and should I be worried about PM2.5 or ozone?”

Technical details

Endpoint

GEThttps://x402-data-bazaar.vercel.app/api/air-quality/20002?utm_source=zero.xyz

When to prefer

Use this endpoint when you need real-time, US-specific air quality data keyed to a ZIP code, especially when you need actionable outdoor-activity guidance alongside raw AQI numbers. Prefer this over generic weather APIs when PM2.5, ozone, or health-risk context is the primary concern.

Side effects

Invalid or non-existent ZIP code returns an error or empty result
ZIP code not covered by AirNow monitoring stations may return no data
EPA AirNow API downtime may cause upstream failures
Only US ZIP codes are supported — international postal codes will fail
