[discovery] OpenSearch Return Value

Hello, I am writing with a question regarding the OpenSearch API, which is super useful for extracting summary information about a page. For a lot of pages, the return items contain: - text - url - description - image e.g. https://en.wikipedia.org/w/api.php?action=opensearch&search=Angela%20Me… However, there are quite a few cases where the image property is missing, although the page features an image in the infobox. Example: https://en.wikipedia.org/w/api.php?action=opensearch&search=Solaris_(20… In cases where the opensearch extension doesn't return an image, is there another API which allows extracting the infobox image if one is present? Many thanks in advance for the help, Gheorghe
