Service description

Multiple stakeholders from banks and brokers to regulators and outsourced managers depend on timely, accurate datasets to make critical decisions. BuiltAPI helps you prepare and maintain standardized, query-ready datasets that serve as trusted sources across your ecosystem. Whether it's a rent roll for underwriting, ESG metrics for compliance, or asset-level KPIs for reporting, these datasets are structured, validated, and always accessible via secure APIs (REST, gRPC, MQTT, GraphQL). This reduces friction, eliminates duplication, and ensures everyone operates on the same reliable foundation automatically.

API-based data sharing enables seamless, secure communication between your systems, partners, and clients. By automatically generating APIs based on your source data, selected schemas, metadata (including user permissions), and query parameters, BuiltAPI ensures that your data is accessible in a transactional manner in real-time.

Why It Matters

Manual data handoffs slow deals and introduce risk. Whether it’s investor reporting, tenant onboarding, or listing space to market, real estate data needs to flow cleanly between platforms and people. BuiltAPI gives you the infrastructure and expert support to automate trusted data exchange—without building from scratch or worrying about governance and compliance.

How to Start

Submit a request for API-based data exchange, our team will define the API endpoints, data objects, and exchange rules relevant to your use case, whether it’s syncing with your internal systems, integrating with third-party platforms, or publishing data for transactions. In just 2 weeks, you'll receive your first secure, documented API — ready to exchange validated data for leasing opportunities, acquisitions, or investor reporting. BuiltAPI ensures your data flows where it’s needed, safely and on your terms.

How It Works

Define Data to Share
Identify the specific data sets you wish to share, including parameters and pipelines. Our team assists in mapping these data sources to ensure they align with your chosen data model.
Decide the Recipient
Determine the third parties (such as banks, brokers, regulators, or outsourced managers) that require access to the data. We help establish secure and efficient data flows tailored to each recipient's needs.
Generate API Documentation
BuiltAPI automatically generates comprehensive documentation in OpenAPI format, detailing endpoint structures, data formats, and integration guidelines. This ensures that recipients can seamlessly connect and interact with the shared data.
Provide API Authentication
We implement robust authentication mechanisms, supplying recipients with the necessary credentials and access controls. This guarantees that data exchanges are secure, compliant, and restricted to authorized parties.
