Answer 1

Magento2 does not have any APi.

So you have to create a new API point for this requirement.

Create below files:

 1. app/code/Devbera/Configurable/etc/webapi.xml

 2. app/code/Devbera/Configurable/etc/di.xml

 3. app/code/Devbera/Configurable/Api/ConfigurableManagementInterface.php

 4. app/code/Devbera/Configurable/Api/ConfigurableManagementInterface.php

Define api point at webapi.xml.

And code is below:

<?xml version="1.0" ?>
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">
  <route method="GET" url="/V1/devbera-configurable/:childId">
      <service class="Devbera\Configurable\Api\ConfigurableManagementInterface"
               method="getParentIdsByChild"/>
      <resources>
          <resource ref="anonymous"/>
      </resources>
  </route>
</routes>

And WebApi interface ConfigurableManagementInterface.php

And code is :

<?xml version="1.0" ?>
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">
  <route method="GET" url="/V1/devbera-configurable/:childId">
      <service class="Devbera\Configurable\Api\ConfigurableManagementInterface"
               method="getParentIdsByChild"/>
      <resources>
          <resource ref="anonymous"/>
      </resources>
  </route>
</routes>

ConfigurableManagement.php for getting parent product

namespace Devbera\Configurable\Model;

use Magento\ConfigurableProduct\Model\Product\Type\Configurable;

/**
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 */
class ConfigurableManagement implements \Devbera\Configurable\Api\ConfigurableManagementInterface
{
    /**
     * @var \Magento\ConfigurableProduct\Model\Product\Type\Configurable
     */
    private $configurable;
    /**
     * @var \Magento\Catalog\Api\ProductRepositoryInterface
     */
    private $productRepository;
    /**
     * @var \Magento\Catalog\Api\Data\ProductInterfaceFactory
     */
    private $productFactory;

    public function __construct(
       Configurable $configurable,
       \Magento\Catalog\Api\ProductRepositoryInterface $productRepository,
       \Magento\Catalog\Api\Data\ProductInterfaceFactory $productFactory
    ) {
        $this->configurable = $configurable;
        $this->productRepository = $productRepository;
        $this->productFactory = $productFactory;
    }

    /**
     * {@inheritdoc}
     */
    public function getParentIdsByChild($childId)
    {
        $parentIds = $this->configurable->getParentIdsByChild($childId);

        $parentList = [];
        if (!empty($parentIds)) {
            foreach ($parentIds as $parentId) {
                $parentList[] = $this->productRepository->getById($parentId);
            }
        }

        return $parentList;
    }
}

And di.xml for rewrite interface with Model management class

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
  <preference for="Devbera\Configurable\Api\ConfigurableManagementInterface"
              type="Devbera\Configurable\Model\ConfigurableManagement"/>
</config>
