/**
 * <p>Lists your things. Use the <b>attributeName</b> and <b>attributeValue</b> parameters to filter your things. For example,
 * 			calling <code>ListThings</code> with attributeName=Color and attributeValue=Red
 * 			retrieves all things in the registry that contain an attribute <b>Color</b> with the value <b>Red</b>. For more
 * 			information, see <a href="https://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html#list-things">List Things</a> from the <i>Amazon Web Services IoT Core Developer
 * 				Guide</i>.</p>
 *          <p>Requires permission to access the <a href="https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions">ListThings</a> action.</p>
 *          <note>
 *             <p>You will not be charged for calling this API if an <code>Access denied</code> error is returned. You will also not be charged if no attributes or pagination token was provided in request and no pagination token and no results were returned.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { IoTClient, ListThingsCommand } from "@aws-sdk/client-iot"; // ES Modules import
 * // const { IoTClient, ListThingsCommand } = require("@aws-sdk/client-iot"); // CommonJS import
 * const client = new IoTClient(config);
 * const input = { // ListThingsRequest
 *   nextToken: "STRING_VALUE",
 *   maxResults: Number("int"),
 *   attributeName: "STRING_VALUE",
 *   attributeValue: "STRING_VALUE",
 *   thingTypeName: "STRING_VALUE",
 *   usePrefixAttributeValue: true || false,
 * };
 * const command = new ListThingsCommand(input);
 * const response = await client.send(command);
 * // { // ListThingsResponse
 * //   things: [ // ThingAttributeList
