Datafiniti Property Data vs Realie Property Data API for AI agents
Datafiniti Property Data is a searchable US property database (API, portal and bulk download) that merges listing activity, tax/assessment and transaction data per property. Realie Property Data API is a US property data API (REST, CLI and MCP) for parcel lookup, property search, owners and comparables; its docs describe property records, not MLS listings.
The short answer
- Datafiniti Property Data: Bulk property and listing-history records for analysis and modelling, billed per record returned.
- Realie Property Data API: Cheap, agent-friendly lookups of US parcel and owner records, not finding homes for sale or rent.
