I can see there are native API's available to query some of the data for repositories in ECR private registry. e.g. https://docs.aws.amazon.com/AmazonECR/latest/APIReference/API_BatchGetImage.html
AWS SDK Go: https://docs.aws.amazon.com/sdk-for-go/api/service/ecr/#ECR.BatchGetImage
This give you the config for an image matching the input criteria.
Does ECR public registry also supports these kinds of native APIs? I know /v2/repo/manifest/tag V2 API available to fetch the config but I'm looking for native/SDK API call.
