Quickstart Guide

Property

Property can be used to:

  • Look up U.S. properties by address, county FIPS (Federal Information Processing Standards) and APN (Assessor's Parcel Number), or Melissa Address Key (MAK)
  • Find the owner's name, address, and value of the home
  • Learn about the various properties and characteristics of a property such as size, rooms, number of buildings, amenities, improvements, etc.
  • Find other properties owned by a homeowner

Single

Batch (LookupProperty Only)

  • Put the input request together using JSON or XML. Put up to 100 records into the request array
  • Make sure to include your license key
  • Specify the output columns you would like to see – they will apply to all records in the request
    • There are many possible outputs, but leaving this option blank and getting the pre-selected default outputs is a good start
    • To see all possible outputs for any of the functions, use “GrpAll”
    • Other output column options are found here: http://wiki.melissadata.com/index.php?title=Property_V4
      • In the “Reference” section under “Input/Output”, go to “Request” for the function you are using
  • Make sure to specify the same options for all records in the batch to maintain consistency
  • Send the full request to the service URL: https://property.melissadata.net/v4/WEB/LookupProperty using HTTP POST
  • Receive the result back for all addresses from the input

LookupDeeds

With a REST request, you can include all the input along with the URL for an easy and quick way of sending a single record.

curl -X GET “https://property.melissadata.net/v4/WEB/LookupDeeds?id=LICENSE_KEY&t=Test&opt=page:1&cols=&mak=&fips=&apn=&txid=&format=JSON&ff=22382%20Avenida%20Empresa%20Rancho%20Santa%20Margarita%20CA%2092688"

LookupHomesbyOwner*

curl -X GET "https://property.melissadata.net/v4/WEB/LookupHomesByOwner?id=LICENSE_KEY&t=Test&mak=&ff=FREEFORM&format=JSON"

*Replace FREEFORM with the primary address of a property owner.

LookupProperty

curl -X GET “https://property.melissadata.net/v4/WEB/LookupProperty?id=LICENSE_KEY&t=Test&format=JSON&cols=&account=&addresskey=&a1=22382%20Avenida%20Empresa&a2=&apn=&city=Rancho%20Santa%20Margarita&country=&fips=&ff=&mak=&state=CA&postal=92688"

You will have to replace the LICENSE_KEY with a real license to generate a result. You can also toggle between getting XML or JSON back using the format input parameter. As you can see, in this example, we are asking for JSON back. JSON is also returned by default when a format is not specified.

For the fastest processing when using any of the Property functions, prioritize the possible inputs in the following order:

  1. FIPS and APN (both must be used)
  2. FIPS and Account Number (both must be used)
  3. MAK
  4. Address Key
  5. Address (parsed or free form)

LookupDeeds

Multiple Historical Deeds - When using LookupDeeds, there may be many historical deeds. The deeds are returned in reverse chronological order, so the first record returned is the most recent. By default, the service returns every available historical deed. If you would only like a specific number of recent records, you may add the option for pagination. For example, in a JSON REST request, you would add &opt=page:X, where X is the number of deeds you would like returned. If no number is specified, the default is 1.

LookupHomesByOwner

Use the Correct Input – To get a list of properties owned by a specific individual, you must input the individual’s primary address using either a freeform address or MAK. Using any property owned by the individual is not sufficient.

LookupProperty

Service Codes – Some of the output columns are populated with service codes. For example, possible results for “Fireplace” are various numbers, such as "1" and "10", which means "Yes" and "Wood Stove", respectively. Results are based on the level of detail that the county provides. Service codes can be found here: http://wiki.melissadata.com/index.php?title=Property_V4%3ALookupProperty_Service_Codes

If you would prefer to have short descriptions returned instead of the service codes, you can toggle the option parameter called Desc from off (default) to on.

  • REST: opt=desc:[on/off]
  • POST:
    • XML: <Options>Desc:[on/off]</Options>
    • JSON: "Options": "Desc:[on/off]",

Narrow Down Your Outputs – Look at the possible outputs (found here: http://wiki.melissadata.com/index.php?title=Property_V4%3ALookupProperty#Columns) and narrow them down to what you need when possible. There are hundreds of possible outputs and it will be faster to process your data and easier to analyze your results when unnecessary information is not outputted.

Multiple Property Matches - Depending on the information provided, there may be several possible matches for a property in our database. If that’s the case, we have developed several criteria to return the best match. If the returned property is not the property you were searching for, you can check if there were additional property matches by looking for a “YCXX” (Property Count) code in the Results output. YC01 indicates one match, which is what was returned; YC02 indicates two matches, and so on. If the code is YC02 or greater, the FIPS, APN, and MAK for the other properties (if available), are returned under the “AssociatedParcels” output column. Note that “GrpAssociatedParcels” is not returned by default and must be specified in the columns parameter to be returned.
