Find sensors — Single sensors with their latest reading (PM1, PM2.5, PM10, temperature, humidity, pressure), network and quality check: status, rating 0–10 of the last checked day, the mean rating of the last 7 days and the reasons. Filter by city, country, or a point with a radius; sort=rating puts the most reliable sensors first.
One sensor — One sensor by its id: location, network, license, quality check with rating and reasons, and the latest reading.
Sensor readings — Readings of one sensor: raw (the last 31 days, at most 7 days a call), 5-minute means (the same windows), hourly means (the last 366 days, at most 92 days a call) or daily means (UTC days of the last 366 days, with the quality check of each day). Default: the last 24 hours, or 30 days by day. Times are UTC.
Mean of a group of sensors — The mean of up to 100 sensors per 5 minutes, hour or UTC day, each sensor counted once per bucket, with the number of sensors in each bucket. Windows as in get_sensor_readings; by day at most 92 days a call.
