Integrating mobile hardware specification APIs has historically been difficult due to incomplete and unnormalized data. Raw string formats for specifications, like screen refresh rates and CPU clock speeds, are cumbersome for programming logic. To address this, the Device Specs API was developed, offering a solution to messy and unstructured data. The new API shifts the parsing burden to the backend, providing clean, strongly-typed, and normalized JSON data. This means numbers are actual numbers, booleans are booleans, and complex specifications are presented as structured arrays. For instance, battery capacity is an integer, and NFC availability is a clear boolean, not text. The API also features deep filtering, allowing users to query very specific hardware parameters via URL parameters. This enables complex searches, such as finding devices with a battery capacity over 5000 mAh, at least 8GB of RAM, from Samsung or Xiaomi, and containing "pro" in their model name. The backend is built with ASP.NET Core Web API, while the frontend utilizes a Blazor WebAssembly/Server hybrid. Caddy is used as a reverse proxy and SSL handler for its automatic HTTPS certificate management and clean configuration. The API's documentation and interactive testing are available online for users to explore and provide feedback.
