summary: Schema Inventory
description: 'Return the data-derived schema inventory for an authorized dataset.
Summarizes the knowledge graph by semantic type: per-type instance
counts, representative sample names, and the per-pair relationship
distribution. Wraps the ``get_schema_inventory`` SDK function so it
is accessible over HTTP with an OpenAPI response schema.
Query parameters:
dataset_id: dataset UUID to scope the graph databases.
samples_per_type: max sample instance names per type (default 5).
sort: ``"count"`` (default) orders types by descending count;
``"none"`` preserves discovery order.'
