In rest api, I am using "rest/V1/carts/1/items" method to get the magento cart items. It works well and the result is

"item_id": 1,
"sku": "sk1",
"qty": 4,
"name": "test",
"price": 10,
"product_type": "simple",
"quote_id": "1"

Any option to get product image in cart

Currently magento2 does not provide any single call for this, Here you have to create new module for this.

Magento 2 rest api : Get cart items with images

Follow the Steps to get Product thumbnail Image in Cart through Rest API without POST any values. It will take current thumbnail Image of a product. Rest Url :

Method : GET -> rest/V1/guest-carts/3f260b6e818d2fe56894ed6222e433f8/items

Create a module : code/Vendor_name/Module_name/

 <?php

MagentoFrameworkComponentComponentRegistrar::register(
 MagentoFrameworkComponentComponentRegistrar::MODULE,
 'Hopescode_Mobileshop',

);

Before checking your out put, If you installed the correct method you can check your var/generation/Magento/Quote/Api/Data/CartItemExtension.php has the value like this:

<?php
namespace MagentoQuoteApiData;

/**
 * Extension class for @see MagentoQuoteApiDataCartItemInterface
 */
class CartItemExtension extends MagentoFrameworkApiAbstractSimpleObject implements MagentoQuoteApiDataCartItemExtensionInterface
null
 */
 public function getImageUrl()
 
 return $this->_get('image_url');
 

 /**
 * @param string $imageUrl
 * @return $this
 */
 public function setImageUrl($imageUrl)
 
 $this->setData('image_url', $imageUrl);
 return $this;
