Bem Knowledge Graph API

Read the cross-document knowledge graph — the canonical entities and thedirected 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 toa single bucket; omit it for the unscoped account+environment view.

Where this information came from

This is an independent, third-party profile of Bem Knowledge Graph API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
