Bem Knowledge Graph API is one of 22 APIs that [Bem](https://apis.io/providers/bem/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Knowledge Graph. The published artifact set on APIs.io includes an OpenAPI specification.

Read the cross-document knowledge graph — the canonical entities and the directed relations between them that the Parse pipeline populates when `linkAcrossDocuments` is enabled. - **`GET /v3/entities/{id}/relations`** returns the inbound and outbound edges incident to one entity, split by direction. Supports `direction`, an exact `relationType` filter, and cursor pagination over edges. A merged-away entity id transparently resolves to its surviving canonical entity. - **`GET /v3/knowledge-graph`** returns the graph as `{ nodes, edges }`, paginating over edges. The `nodes` for a page are the distinct endpoint entities of that page's edges (both endpoints of every edge are included). Filter with `type[]`, `since`, and `search`; an edge is returned only when both of its endpoints survive the entity filters. Both endpoints take an optional `bucket` (`bkt_...`) to scope the read to a single bucket; omit it for the unscoped account+environment view.
