GroupDocs.Signature provides a MetadataSearchOptions class to search Metadata electronic signatures within document.
Here are the steps to search for Metadata signatures using GroupDocs.Signature API:

• Create new instance of Signature class and pass source document path as a constructor parameter;
• Instantiate the MetadataSearchOptions object according to your requirements and specify additional search options (if needed);
• Call Search method of Signature class instance and pass MetadataSearchOptions to it.

This code snippet demonstrates how to search for Metadata e-signature in the document.

using (Signature signature = new Signature("sample.pdf"))
{
    MetadataSearchOptions options = new MetadataSearchOptions();
    // search for signatures in document
    List<MetadataSignature> signatures = signature.Search<MetadataSignature>(options);
    foreach (var metadataSignature in signatures)
    {
        Console.WriteLine("Metadata signature found. Name : {0}. Value: {1}. Type: {2}", metadataSignature.Name, metadataSignature.Value,metadataSignature.Type);
    }
}
