Represents the API client for interacting with the Literal service. This class handles API requests, authentication, and provides methods for various operations supported by the Literal API. To use this API, you need to initialize a LiteralClient and access the API through it: 
const literalAiClient = new LiteralClient({apiKey: process.env["LITERAL_API_KEY"]});
const api = literalAiClient.api;
Then you can use the api object to make calls to the Literal service.
