About ParcelBase

Property data infrastructure for the modern developer.

ParcelBase provides API access to comprehensive US property data covering 145 million residential and commercial properties across all 50 states. Our platform is built for developers, data teams, and businesses that need reliable property intelligence at scale.

We aggregate data from county assessors, tax records, deed filings, mortgage recordings, and public record sources to deliver a unified property record through a single API call. Our data is updated regularly and covers ownership, valuations, tax history, mortgage details, sales transactions, and property characteristics.

Our Approach

  • Complete records — Every API call returns the full property profile. No tiered packages or per-field fees.
  • Developer-first — RESTful JSON API with standard authentication, pagination, and detailed documentation.
  • Transparent pricing — Volume-based plans with no hidden charges or long-term commitments.
  • Nationwide coverage — Data across all 50 US states with consistent formatting and field structure.
