About the api.developer.attomdata.com API

The ATTOM Data API exposes 5 endpoints covering property search, detailed property attributes, owner records, neighborhood points of interest, and geographic sales trends. get_property_detail_owner returns current ownership data alongside full property records, while get_transaction_sales_trend aggregates yearly or monthly transaction metrics for a given geography — useful for market analysis pipelines that need structured, address-level real estate data.

Property Search and Detail

get_property_address accepts street address components (address1, address2), a postal code, or a latitude/longitude pair with an optional radius (in miles) to return a paginated property array matching those criteria. get_property_detail narrows to a single property using either an attomid or a full address, returning a rich property array with detailed attribute fields. get_property_detail_owner requires an attomid and adds current owner information to that same structure — ownership data is only accessible through this dedicated endpoint, not through the general detail call.

Sales Trends by Geography

get_transaction_sales_trend returns a salesTrends array for a target geography defined by a geoidv4 — a 32-character hex identifier available in the geoIdV4 field of property responses. Required inputs are startyear, endyear, and geoidv4. The interval parameter accepts 'yearly' or 'monthly'. Geography type is encoded in the ID prefix: ZI for ZIP code, CO for county, PL for place, CS for census tract, and DB for district. An optional propertytype filter narrows results to a specific asset class.

Points of Interest

get_poi_search returns a poi array for locations near an address, ZIP code, or a WKT-style point string formatted as POINT(longitude,latitude). A categoryid parameter filters by POI type. The recordlimit parameter caps results (default 20), and standard page/pagesize parameters control pagination across larger result sets.

Common use cases
  • Enriching property listings with ownership records pulled from get_property_detail_owner
  • Building neighborhood scorecards by querying nearby amenities via get_poi_search with categoryid filters
  • Generating market trend dashboards using get_transaction_sales_trend with monthly interval data over multi-year ranges
  • Geocoding-free property lookups by passing address1 and address2 to get_property_detail
  • Radius-based property prospecting by supplying latitude, longitude, and a mile radius to get_property_address
  • Comparing sales velocity across ZIP codes and counties by switching geoidv4 prefixes in trend queries
  • Populating CRM records with structured property attributes from the property response array

Frequently asked questions
Does ATTOM Data have an official developer API?+
Yes. ATTOM Data Solutions provides an official API documented at https://api.developer.attomdata.com. The Parse API surfaces a curated subset of that platform's property, owner, POI, and sales trend endpoints.
How do I obtain the `geoidv4` value needed for sales trend queries?+
get_transaction_sales_trend requires a geoidv4 that comes from the geoIdV4 field returned in property responses — for example, from get_property_detail. The prefix of the 32-character hex hash encodes geography type: ZI for ZIP code, CO for county, PL for place, CS for census, and DB for district. There is no dedicated endpoint to look up geography IDs independently.
Does the API return historical ownership or mortgage/lien data?+
Not currently. Owner data is limited to current ownership information from get_property_detail_owner. Historical ownership chains, mortgage records, and lien data are not exposed by these endpoints. You can fork this API on Parse and revise it to add endpoints that cover those additional ATTOM data products.
What is the difference between `get_property_detail` and `get_property_detail_owner`?+
get_property_detail accepts either an attomid or an address pair and returns property attribute data. get_property_detail_owner requires an attomid and returns that same property structure augmented with current owner information. Owner fields are not present in the base detail response.
Are property valuation estimates (AVMs) or rental estimates included in any endpoint?+
Not currently. The five endpoints cover property attributes, owner records, POI proximity, and sales trend aggregates. Automated valuation model (AVM) outputs and rental price estimates are not part of this API's response fields. You can fork this API on Parse and revise it to add an endpoint targeting ATTOM's valuation data products.
