Setup: Install the `needle-python` library and set your Needle API key. .. code-block:: bash pip install needle-python export NEEDLE_API_KEY="your-api-key" Key init args: - `needle_api_key` (Optional[str]): API key for authenticating with Needle. - `collection_id` (str): Needle collection to load documents from. Usage: .. code-block:: python from langchain_community.document_loaders.needle import NeedleLoader loader = NeedleLoader( needle_api_key="your-api-key", collection_id="your-collection-id" ) # Load documents documents = loader.load() for doc in documents: print(doc.metadata) # Lazy load documents for doc in loader.lazy_load(): print(doc.metadata) Nneedle_api_key collection_idreturnc ddlm}t|||_||_d|_|j r||j |_|j s tdy#t$r tdwxYw)a Initializes the NeedleLoader with API key and collection ID.
