Our Real Estate API offers a powerful feature that allows you to request real-time market statistics. This capability is invaluable for creating data visualizations, providing users with deep market insights to make more informed decisions. The feature offers a high level of granularity, enabling you to request specific scopes of market data just as you would when filtering listings.

How to Request Statistics

Step 1: Provide the Scope of Data

Begin by defining the scope of the data you wish to analyze using the GET /listings endpoint. This scope is defined in the same way you would filter for listings. For example, if you want statistics for 4-bedroom homes in New York City that have sold in the past 2 years, your request URL will look like this:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01

Step 2: Specify the Statistics

To retrieve specific statistics, use the statistics parameter. For example, if you're interested in the average sold price, add &statistics=avg-soldPrice to your request. The full request URL would be:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice

This request will return all relevant listings along with a statistics object containing the average sold price:

{
  "statistics": {
    "soldPrice": {
      "avg": 823702
    }
  }
}

Requesting Only Statistics

If you do not need the listings and only require the statistics, add &listings=false to your request. This can significantly reduce response time. For instance:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice&listings=false

Grouping Statistics

You can group statistics by different time periods to analyze trends. For example, to see how the average sold price has changed month-to-month over the past 2 years, add grp-mth as a comma-separated value to the statistics parameter:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice,grp-mth&listings=false

The response will include monthly data points:

{
  "statistics": {
    "soldPrice": {
      "avg": 823702,
      "mth": {
        "2022-07": {
          "avg": 743897,
          "count": 13303
        },
        "2022-08": {
          "avg": 759084,
          "count": 25539
        },
        "2022-09": {
          "avg": 739097,
          "count": 22919
        },
        ...
      }
    }
  }
}

Supported Groupings

grp-day - By day
grp-mth - By month
grp-yr - By year
grp-{x}-days - Rolling statistics, where x is the number of days for each grouping

Rolling Statistics

Rolling statistics provide a moving average over a specified period, smoothing out fluctuations to reveal underlying trends. For instance, to get a rolling average of the sold price over 30 days:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice,grp-30-days&listings=false

Requesting Multiple Statistics

You can request multiple statistics in a single API call. For example, to retrieve both the average sold price and average days on market you can do so by comma-separating the values avg-daysOnMarket and avg-soldPrice in the statistics parameter:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-daysOnMarket,avg-soldPrice,grp-mth&listings=false

Aggregating Statistics

Aggregating statistics allows you to compare different segments within your data. To enable aggregation, add &aggregateStatistics=true and specify the field to aggregate by. For instance, to compare average sold prices by neighborhood:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice,grp-mth&listings=false&aggregateStatistics=true&aggregates=address.neighborhood

The response will be grouped by neighborhood:

{
  "statistics": {
    "soldPrice": {
      "avg": 986486,
      "mth": {
        "2022-07": {
          "avg": 949437,
          "count": 4600,
          "aggregates": {
            "address": {
              "neighborhood": {
                "Waterfront Communities C1": {
                  "count": 74,
                  "avg": 805367
                },
               "Waterfront Communities C2": {
                  "count": 60,
                  "avg": 709361
                },
                ...
              }
            }
          }
        }
      }
    }
  }
}

You can aggregate statistics by various fields. For example, to compare sold prices across different property types:

https://api.repliers.io/listings?city=New York&minBeds=4&maxBeds=4&status=U&lastStatus=Sld&minSoldDate=2022-07-01&statistics=avg-soldPrice,grp-mth&listings=false&aggregateStatistics=true&aggregates=details.propertyType

The response will include data segmented by property type:

{
  "statistics": {
    "soldPrice": {
      "avg": 986486,
      "mth": {
        "2022-07": {
          "avg": 949437,
          "count": 4600,
          "aggregates": {
            "details": {
              "propertyType": {
                "Detached": {
                  "count": 2526,
                  "avg": 1090041
                },
                "Condo Apt": {
                  "count": 844,
                  "avg": 696919
                },
                ...
              }
            }
          }
        }
      }
    }
  }
}
