For on-demand indexes, since vector values are retrieved from object storage, fetch operations may have increased latency. If you only need metadata or IDs, consider using the query operation with `includeValues` set to `false` instead. For guidance and examples, see [Fetch data](/guides/manage-data-fetch-data). ```python Python theme={null} # pip install "pinecone[grpc]" from pinecone.grpc import PineconeGRPC as Pinecone pc = Pinecone(api_key="YOUR_API_KEY") # To get the unique host for an index, # see https://docs.pinecone.io/guides/manage-data/target-an-index index = pc.Index(host="INDEX_HOST") index.fetch(ids=["id-1", "id-2"], namespace="example-namespace") ``` ```javascript JavaScript theme={null} // npm install @pinecone-database/pinecone import { Pinecone } from '@pinecone-database/pinecone' const pc = new Pinecone({ apiKey: 'YOUR_API_KEY' }) // To get the unique host for an index, // see https://docs.pinecone.io/guides/manage-data/target-an-index const index = pc.index("INDEX_NAME", "INDEX_HOST") const fetchResult = await index.namespace('example-namespace').fetch(['id-1', 'id-2']);
