List vector stores

Retrieve a paginated list of vector stores for a project.

This endpoint returns all vector stores associated with the specified project, with optional filtering by name and engine type.

Filtering:

• name: Filter vector stores by exact name match
• engine: Filter by vector store engine type (e.g., sgp_knowledge_base)
• ids: Filter by vector store IDs (list)
• created_at_start: Filter by creation time (start)
• created_at_end: Filter by creation time (end)
• project_id: Filter by project ID (if not provided in path)

Sorting:

• sort_by: Field to sort by (id, created_at, engine, project_id)
• sort_order: Sort order (asc or desc)

Token-based Pagination:

• New syntax (recommended): Use page_size, continuation_token, sort_by, sort_order query parameters
• Legacy syntax (deprecated): Use size and continuation_token query parameters
• If no pagination parameters are provided, returns a plain list
• Use the next_token from the response to fetch subsequent pages
• When next_token is null, you have reached the last page

Returns:

• Paginated list of vector store entities
• Total count of matching vector stores
• next_token for pagination (null if no more pages)
