Capabilities5 decomposed
deterministic address resolution
Medium confidenceThis capability resolves any US street address to detailed property information using a deterministic algorithm that queries a comprehensive database of zoning, permit history, assessed values, and planning cases. It employs a caching mechanism to ensure responses are sub-200ms for frequently accessed addresses, enhancing performance and user experience. The architecture leverages a RESTful API design, allowing seamless integration with various applications and services.
Utilizes a deterministic algorithm for address resolution, ensuring consistent and reliable results across multiple queries.
More reliable than generic geocoding services because it provides detailed zoning and permit data specific to US properties.
permit history retrieval
Medium confidenceThis capability allows users to fetch the complete permit history for a given address, utilizing a structured query to access a historical database of permits linked to that property. The API returns data in a standardized format, making it easy to integrate into other systems or applications. This feature is particularly useful for developers looking to assess property modifications over time.
Integrates a historical database specifically focused on permits, providing a comprehensive view of property changes over time.
Offers more detailed and localized permit information compared to general construction databases.
zoning information access
Medium confidenceThis capability provides users with zoning information for a specified address by querying a dedicated zoning database. The API returns zoning classifications, restrictions, and relevant planning cases, which are essential for developers and investors to understand property usage regulations. The integration is designed to be straightforward, allowing for quick access to zoning data.
Focuses on providing zoning information directly linked to property addresses, ensuring accuracy and relevance for urban development.
More comprehensive than general zoning lookup services, as it includes planning case data and local regulations.
neighborhood data retrieval
Medium confidenceThis capability retrieves neighborhood-level data associated with a given address, including demographic information, local amenities, and community resources. It uses a combination of public datasets and proprietary data to provide a holistic view of the neighborhood, which is crucial for potential buyers and investors. The API ensures that this data is returned in a structured format for easy consumption.
Combines multiple data sources to provide a comprehensive overview of neighborhood characteristics, enhancing property evaluation.
More detailed than standard neighborhood lookup tools, as it includes both demographic and amenity data.
status code interpretation
Medium confidenceThis capability interprets and returns hard status codes such as RESOLVED, NO_MATCH, MULTIPLE_MATCH, and DATA_UNAVAILABLE for each API call. It provides users with clear feedback on the success or failure of their queries, helping them understand the results without ambiguity. The status codes are designed to be informative, guiding users on the next steps based on the outcome.
Provides a standardized set of status codes that clearly communicate the outcome of address queries, enhancing user experience.
More informative than generic API status codes, as it includes specific context related to address resolution.
