Landexar Integration Guides
Step-by-step guides for integrating Landexar property intelligence into your application — from your first API request through enterprise data delivery.
Getting Started
Everything you need to make your first Landexar API request — account setup, API key provisioning, and a working example in under five minutes.
Your First API Request
Provision an API key, authenticate, and retrieve a property record for any address.
- Sign up for a Landexar Professional or Enterprise account at landexar.com/signup
- Navigate to Settings → Developer → API Keys and generate a new key
- Make a test request to GET /auth/me to confirm your credentials are working
- Resolve your first address using GET /properties/resolve?address=<address>
- Inspect the response — note the property ID, source attribution, and confidence fields
Understanding the Response Structure
Learn how Landexar structures property records — source attribution, confidence levels, and data freshness indicators.
- Every record includes a source field identifying the originating agency or system
- confidence values are high, medium, or low based on source quality and recency
- last_verified is the date the record was last confirmed against its source
- Use these fields to assess data quality before relying on a record in your application
Rate Limits and Pagination
Understand rate limit headers, handle 429 responses, and paginate through large result sets.
- Rate limits are returned in X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers
- When you receive a 429, wait until the X-RateLimit-Reset timestamp before retrying
- List endpoints return a next_cursor field when more results are available
- Pass cursor=<next_cursor> as a query parameter to retrieve the next page
API access requires a Landexar Professional or Enterprise plan. Contact [email protected] to discuss integration requirements or request access.
