I don’t think that API exists. The only way to fetch data is to is by providing the list of IDs you want to fetch, at least according to the fetch API docs, which implies that you’re tracking them somewhere outside of Pinecone.
I’d love to see the fetch API expanded to take these optional arguments, consistent with the query endpoint:
namespacefor limiting to a specific namespacefilterfor filtering by metadataincludeMetadataflag for including metadata in the responseincludeValuesflag for including vector values in response
