| GET | `https://api.digital.tfl.gov.uk/AirQuality` | Gets air quality data feed |
| GET | `https://api.digital.tfl.gov.uk/BikePoint` | Gets all bike point locations. The Place object has an addtionalProperties array which contains the nbBikes, nbDocks and nbSpaces
            numbers which give the status of the BikePoint. A mismatch in these numbers i.e. nbDocks - (nbBikes + nbSpaces) != 0 indicates broken docks. |
