We've updated our API documentation with several improvements to help you get the most out of the BatchData API. Here's what's new.
Simplified Property Lookup Address Input
The Property Lookup API documentation now shows only the address fields that the endpoint actually uses:
street— Include unit/apartment info directly in this fieldcitystatezipzipPlus4county
Previously, the documentation displayed additional fields that were not used by the Property Lookup endpoint. The updated documentation reflects the actual supported input.
Unit/Apartment Addresses
When looking up properties with unit numbers, include the unit information in the street field:
{
"requests": [
{
"address": {
"street": "123 Main St Apt 4B",
"city": "Phoenix",
"state": "AZ",
"zip": "85001"
}
}
]
}
This is a documentation-only update — the API behavior has not changed and existing integrations will continue to work as expected.
Land Use Code Search
The Property Search API now documents standardizedLandUseCode as a searchable filter, giving you a more precise way to find properties by type.
Why this matters: Some property type descriptions like "Vacant Land" appear in multiple categories (Residential, Commercial, Industrial). Searching by propertyTypeDetail alone can return mixed results. Land use codes eliminate this ambiguity.
Example: Search for commercial vacant land only:
{
"searchCriteria": {
"query": "Phoenix, AZ",
"general": {
"standardizedLandUseCode": {
"equals": "C60"
}
}
}
}
You can also search for multiple property types at once using inList:
{
"searchCriteria": {
"query": "Maricopa County, AZ",
"general": {
"standardizedLandUseCode": {
"inList": ["R2", "R7", "R43"]
}
}
}
}
Common land use codes:
Code | Category | Property Type |
R2 | Residential | Single Family |
R7 | Residential | Condo |
R43 | Residential | Vacant Land |
C60 | Commercial | Vacant Land |
C51 | Commercial | Office Building |
To find the code for any property type, use Property Lookup to retrieve a sample property and check the general.standardizedLandUseCode value in the response.
For a complete list of codes, see the Land Use Code Reference.
New Building Search Filters
Two building-related search filters are now documented in the Property Search API:
building.commercialUnitCount— Filter properties by number of commercial unitsbuilding.livingAreaSquareFeet— Filter properties by living area square footage
Both filters support min and max range values:
{
"searchCriteria": {
"query": "Phoenix, AZ",
"building": {
"commercialUnitCount": {
"min": 1
},
"livingAreaSquareFeet": {
"min": 1500,
"max": 3000
}
}
}
}
These filters were already supported by the API but were not previously included in the documentation.
No Code Changes Required
All updates described above are documentation improvements only. The API behavior has not changed — your existing integrations will continue to work as expected.
