Four ways developers use the property data API in production
Auto-enrich addresses as they enter your pipeline. When a new property hits your CRM, call the lookup endpoint to attach owner names, phones with DNC flags, emails, and mailing address -- zero manual data entry.
Instant property intelligence before making offers. Get estimated value, equity, mortgage balance, tax status, and ownership flags in one call -- no spreadsheets, no manual research.
Track property values and ownership changes across your portfolio. Schedule periodic lookups to detect equity shifts, new mortgages, pre-foreclosure status, or ownership transfers.
Embed property data in your own product. Give your users property intelligence, owner contacts, and compliance flags without building the data layer yourself. Our API powers your branded experience.
