By default, Magento 2 in API side does not provide any API for Merge guest cart with customer card when the customer is login.

But you can replace the guest cart with customer cart.

API : (/V1/carts/:cartId) 
File : vendor/magento/module-quote/Model/QuoteManagement.php
Function : public function assignCustomer($cartId, $customerId, $storeId)

But if you want to develop functionality Merge cart Live Magento web side you need to create custom API.

You need to create "Around" Plugin in your custom extension.
