        - filename: Optional filename to help determine content type
        - metadata: Optional metadata dictionary
        - rules: Optional list of rules. Each rule should be either:
               - MetadataExtractionRule: {"type": "metadata_extraction", "schema": {...}}
               - NaturalLanguageRule: {"type": "natural_language", "prompt": "..."}
    auth: Authentication context

Returns:
    Document: Metadata of ingested document

Ingest Text

Ingest a file document.

Args:
    file: File to ingest
    metadata: JSON string of metadata
    rules: JSON string of rules list. Each rule should be either:
           - MetadataExtractionRule: {"type": "metadata_extraction", "schema": {...}}
           - NaturalLanguageRule: {"type": "natural_language", "prompt": "..."}
    auth: Authentication context

Returns:
    Document: Metadata of ingested document

Ingest File

Batch ingest multiple files.

Args:
    files: List of files to ingest
    metadata: JSON string of metadata (either a single dict or list of dicts)
    rules: JSON string of rules list. Can be either:
           - A single list of rules to apply to all files
           - A list of rule lists, one per file
    use_colpali: Whether to use ColPali-style embedding
    parallel: Whether to process files in parallel
    auth: Authentication context

Returns:
    BatchIngestResponse containing:
        - documents: List of successfully ingested documents
        - errors: List of errors encountered during ingestion

Batch Ingest Files

Retrieve Chunks

Retrieve Documents

Retrieve multiple documents by their IDs in a single batch operation.

Batch Get Documents

Retrieve specific chunks by their document ID and chunk number in a single batch operation.

Batch Get Chunks

Generate completion using relevant chunks as context.

When graph_name is provided, the query will leverage the knowledge graph 
to enhance retrieval by finding relevant entities and their connected documents.

Query Completion

List Documents

Get Document
