Technical details
Endpoint
POSThttps://energybilltoolkit.co.uk/air/api/tools/get-air-qualityWhen to prefer
Use this endpoint when you need real-time, postcode-level air quality data sourced directly from DEFRA UK-AIR monitoring stations. Prefer this over generic air quality APIs when the user is specifically in the UK and needs official government-sourced pollutant readings tied to a precise postcode location.
Side effects
- Invalid or malformed UK postcode returns an error
- No nearby monitoring stations found for remote postcodes
- DEFRA UK-AIR upstream data unavailable or stale
- Postcode outside UK coverage area
- Missing required postcode parameter in request body
