REalyse API.
Programmatic access to UK property market data for development teams building proptech applications, automated valuation models, and custom analytics platforms.
The Workflow Shift
How the API changes the job.
TodayWith API
Aggregate
TodayAggregating property data from multiple providers means building and maintaining costly pipelines before you can ship anything.
With APIOne RESTful API delivers UK-wide property data at postcode, ward, local-authority, or national level through a single endpoint.
Prepare
TodayRaw sources arrive inconsistent and unvalidated, so engineering time goes to cleaning data instead of your product.
With APIData arrives pre-processed and validated, so your team builds on analysis-ready inputs from day one.
Integrate
TodayEvery new data integration slows your roadmap. Documentation gaps and bespoke formats stretch timelines.
With APIOfficial SDKs for Python, JavaScript, and R, comprehensive documentation, and a sandbox environment shorten time to integration.

Frequently Asked Questions
Request API access through our contact form. We will provision a sandbox environment with test data so you can start building immediately. Full API documentation is available once your account is active.
The API provides access to the same comprehensive dataset available in Core and Pulse, including transaction data, pricing indices, demographics, planning data, and market indicators.
Rate limits depend on your plan tier. Standard plans include generous limits suitable for most applications. High-volume and real-time streaming use cases are supported on Enterprise plans with custom rate limits.
Yes. The API is designed for production workloads, with an uptime SLA, dedicated support, and comprehensive monitoring available on Enterprise plans.
Use Core if your team needs an interactive research interface. Use Pulse for ready-to-use monitoring dashboards. The API is best when you want to embed REalyse data directly into your own applications, models, or workflows.
