Retain memories

POST 
/v1/default/banks/:bank_id/memories

Retain memory items with automatic fact extraction.

This is the main endpoint for storing memories. It supports both synchronous and asynchronous processing via the async parameter.

Features:

  • Efficient batch processing
  • Automatic fact extraction from natural language
  • Entity recognition and linking
  • Document tracking with automatic upsert (when document_id is provided)
  • Temporal and semantic linking
  • Optional asynchronous processing

The system automatically:

  1. Extracts semantic facts from the content
  2. Generates embeddings
  3. Deduplicates similar facts
  4. Creates temporal, semantic, and entity links
  5. Tracks document metadata

When async=true: Returns immediately after queuing. Use the operations endpoint to monitor progress.

When async=false (default): Waits for processing to complete.

Note: If a memory item has a document_id that already exists, the old document and its memory units will be deleted before creating new ones (upsert behavior).

Authentication required — include an Authorization: Bearer hsk_... header. See Authentication for details.
