This API provides structured and reliable access to information on US mortgage rates, allowing you to efficiently query up-to-date data by product type. It is designed to facilitate integration with web and mobile applications and analytics systems that require clear and consistent information on credit conditions.
The service response is delivered in JSON format, ensuring compatibility with a wide variety of programming languages and technological environments. Each request includes a descriptive message confirming the result of the operation and a Boolean success indicator, allowing consumer systems to easily validate the response and manage potential errors within automated processes.
The main data field contains a collection of records, where each element represents a specific financial product. Each record includes a unique identifier that ensures data traceability and reference, as well as contextual information such as the country of origin, in this case the United States. This structure allows the API to be scaled to include multiple regions or additional products in the future.
The interest rate value is presented in a standardized format, facilitating its visualization, processing, and use in financial calculations. This makes the API ideal for product comparison tools, credit simulators, information panels, and financial advisory systems.
Overall, this API offers a robust, flexible, and scalable solution focused on simplifying access to relevant mortgage data. By centralizing information in a single endpoint, it reduces integration complexity, improves data consistency, and supports informed decision-making in modern financial environments.

The GET US Mortgages endpoint returns current U.S. mortgage rates by product type, including interest rates and unique identifiers. The GET Historical endpoint provides historical mortgage rates, also including product type, interest rates, and timestamps.
Key fields in the response data include "id" (unique identifier), "country" (location of the rates), "timestamp" (last updated time), "product" (type of mortgage), and "interest_rate" (current or historical rate value).
The response data is organized in a JSON format, containing a "message" field for status, a "success" Boolean indicator, and a "data" array that holds individual records for each mortgage product, each with its own set of fields.
The GET US Mortgages endpoint provides current mortgage rates, while the GET Historical endpoint offers past mortgage rates. Both endpoints include product type, interest rates, and unique identifiers for traceability.
Currently, the API does not specify parameters for customizing requests. Users can retrieve all available mortgage rates or historical data by calling the respective endpoints without additional parameters.
Typical use cases include developing mortgage comparison tools, financial advisory systems, credit simulators, and information panels that require up-to-date or historical mortgage rate data for analysis and decision-making.
Data accuracy is maintained through reliable sources and regular updates. The API provides timestamps for each rate, allowing users to verify the recency of the information.
Users can expect a consistent structure in the response data, with each mortgage product represented as an object in the "data" array. Each object will include the same key fields, facilitating easy parsing and integration into applications.
