GraphQL layer over zoopla's API

Zoopla graphql

GraphQL layer over Zoopla's and Google's Maps APIs

What it does

Easily search the Zoopla database for property listings, and only pick out the bits you're interested in for your interface. On top of that you can find the walking distance to a station within the vicinity, AND THEN how long it will take to commute from those said stations to a destination of your choice 🚶‍️🏡🚂😊

Examples

Example query:

{
  listings(area: "walthamstow", status:SALE) {
    count
    properties {
      agent {
        name
      }
      price {
        current,
        history {
          date
          percent
        }
      }
      location {
        transport {
          trainStations(maxWalkTime:10) {
            name
            gettingThere {
              walking {
                time {
                  minutes
                }
              }
            }
            commuteTo(destination:"london bridge") {
              time {
                minutes
              }
            }
          }
        }
      }
    }
  }
}
