# API Service Libraries

Quadrata SDK API Service Libraries

On the following pages are examples for how to work with each of the API services.

The response from each API endpoint is mapped in `@quadrata/sdk/types` under the `API.DTO` namespace.

The parameters and parsed responses for each service are mapped in `@quadrata/sdk/types` under the `API.Services` namespace.
