ATTOM Data — Sourcing Notes

ATTOM is a US B2B property-data aggregator that resells comprehensive tax, foreclosure, mortgage and AVM data via API and bulk files rather than listing properties, and it is licensed under contract, not scraped. It is one of the most comprehensive US property-data providers. PropAPIS treats it as a sourcing/partnership reference, not a parse target.

Platform Overview

Market Position

• One of the most comprehensive US property-data providers (tax, deed, foreclosure, mortgage, AVM)
• A data aggregator that resells structured datasets rather than operating a consumer listings portal
• Delivered via a paid B2B API and bulk-file products — acquired by license, not scraping (ATTOM data-provider review, 2026)
• A potential sourcing partner or competitor to PropAPIS, depending on use case

Why It Is Not a Parse Target

ATTOM does not publish a consumer listings site to extract — it sells curated datasets and an API under license. The right way to obtain its data is a B2B contract, so PropAPIS documents it here for sourcing and competitive context rather than offering an extraction endpoint.

Coverage

Data Coverage:

• United States (nationwide property and tax records)
• ~150M+ US properties (vendor scale)
• Tax, deed, foreclosure, mortgage and AVM fields
• Neighborhood and risk data

Data Fields Available

ATTOM holds deep structured US property data, typically licensed via API or bulk files:

Tax & Financial Data

• Tax: Assessed values and tax records
• Mortgage: Loan and lien records
• Foreclosure: Pre-foreclosure and auction data
• AVM: Automated valuation models

Property & Ownership Data

• Property Attributes: Beds, baths, area, lot
• Ownership: Title and ownership records
• Sales History: Historical deed/transaction data
• Neighborhood: Boundaries and area context

Note: PropAPIS does not extract ATTOM data. These fields describe what ATTOM licenses directly; obtain them through an ATTOM B2B agreement or API.

API Endpoints

ATTOM exposes its data through its own paid B2B API and bulk-data products — not through PropAPIS extraction. The snippets below illustrate how you might combine ATTOM-licensed data alongside PropAPIS listing data in your own pipeline.

Combine Licensed Data With PropAPIS Listings

from propapis import PropAPIS
 
api = PropAPIS(api_key='your_api_key')
 
# PropAPIS provides live listings; ATTOM (licensed) provides tax/foreclosure/AVM.
# Fetch listings from a portal PropAPIS does extract, then enrich.
listings = api.platforms.zillow.search(state='CA', purpose='for-sale')
 
for listing in listings[:5]:
    print(f"{listing.title} - USD {listing.price:,}")
    # enrich with your licensed ATTOM tax/AVM record here (B2B contract required)

Quick Start

from propapis import PropAPIS
 
# PropAPIS does not resell ATTOM data — license it from ATTOM directly.
# Use PropAPIS for live listings and enrich with your ATTOM dataset.
api = PropAPIS(api_key='your_api_key')
 
listings = api.platforms.zillow.search(state='TX', purpose='for-sale')
for listing in listings[:5]:
    print(f"{listing.title} - USD {listing.price:,}")

import { PropAPIS } from 'propapis';
 
// PropAPIS does not resell ATTOM data — license it from ATTOM directly.
// Use PropAPIS for live listings and enrich with your ATTOM dataset.
const api = new PropAPIS({ apiKey: 'your_api_key' });
 
const listings = await api.platforms.zillow.search({
  state: 'TX',
  purpose: 'for-sale',
});
 
listings.slice(0, 5).forEach((l) => {
  console.log(`${l.title} - USD ${l.price.toLocaleString()}`);
});

# PropAPIS does not resell ATTOM data — license it from ATTOM directly.
# PropAPIS provides live listings you can enrich with an ATTOM dataset.
curl "https://api.propapis.com/v1/platforms/zillow/search?state=TX&purpose=for-sale" \
