Steps
Register a free Airthings account and create a Consumer API client (client_id + client_secret) via consumer-api-doc.airthings.com/dashboard or dashboard.airthings.com/integrations/api-integration with the 'read:device:current_values' scope.
Request an OAuth2 client_credentials access token: POST https://accounts-api.airthings.com/v1/token with client_id, client_secret and grant_type=client_credentials.
Use the returned JWT bearer token in the Authorization header for GET https://consumer-api.airthings.com/v1/devices to list your registered devices.
Call GET https://consumer-api.airthings.com/v1/devices/{serialNumber}/latest-samples to retrieve the device's latest radon, CO2, VOC, humidity, temperature and PM readings.
Re-request a new token via the same client_credentials call when the JWT expires; this flow has no refresh token.
Known gotchas
This is a read-only, personal-use-only consumer tier limited to devices on your own account, not fleet/business data.
Docs live at consumer-api-doc.airthings.com, a separate site from the Business docs at developer-business.airthings.com — don't mix up client registration dashboards.
