I think you are referring to the attribute "webLinks" which is called Sources in WC1 UI.
Sources tab in UI displays a list of links that may potential negative news about the entity. The Sources tab in UI is provided in the array "webLinks" in the API.
For the first question, webLinks in API is an array which contains three fields in it. Please find the format of each attribute below:
"caption" : string
"tags": <string> array
For your second question, the links provided in the API do not re direct to World Check which happens in the UI which gives the WC1 UI the capability to translate the content. API just displays the link and the user has to extract the link from the API response and open it in a browser, hence the translating responsibilities falls on the browser itself as the doc does not open in the WC UI app.
Can you please elaborate your query regarding the translation of the flow of the information?
Also, is first part of the question is same as the link below:
No. Actually by format I mean : html, string, ...
Concerning the translation: The Web solution is providing some translation capabilities, my question is does the API offering them too. Can we for exemple ask to have the article in french automatically ?
