To use the GDC API, researchers typically begin by constructing a query URL that specifies the desired data. The API supports various query parameters that can be combined to narrow down the data of interest. For example, a query might specify a particular cancer type, a set of genes, or a range of mutation frequencies.
The API endpoints are organized into categories such as cases, files, projects, and annotations. Each endpoint provides access to a specific type of data or metadata, making it easy to locate and retrieve the necessary information.
