Air quality API live US & EU AQI.
Live air-quality index (US & EU scales) by city or coordinates, with the pollutant breakdown.
The call
Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.
# REST (free key)
curl -H "X-API-Key: $KEY" "https://dynamicfeed.ai/air-quality?city=Delhi"
# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call:
air_quality(city="Delhi")Sample response
