I'm reading about LlamaIndex data agents:
https://medium.com/llamaindex-blog/data-agents-eed797d7972f One of the use cases agents can solve is: "Calling any external service API in a structured fashion. They can either process the response immediately or index/cache this data for future use." Is there any example of how I would do this? I want to connect to newsapi, read the news and store it in VectorIndex if it is not there yet.
