Family Office Knowledge Graph

Family Office Knowledge Graph is an agentic data platform that aggregates public records of family offices worldwide. Operated by Agentic KG Holdings, it provides a searchable graph of entities, their legal identifiers, jurisdictions, structures, and related metadata, sourced from the Global Legal Entity Identifier Foundation (GLEIF) and national registers. The service exposes this data via a Model Context Protocol (MCP) door, enabling automated access for downstream applications and analytics.

Family Office Knowledge Graph publishes 7 API contracts indexed on the APIs.io network, including Facts.json API, Family Office Knowledge Graph — The Doors API, MCP API, and 4 more. Tagged areas include Data, Finance, Graph, Public Records, and Family Offices.

The Family Office Knowledge Graph catalog on APIs.io includes 1 Spectral governance ruleset.

Family Office Knowledge Graph’s developer surface includes API reference and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/familyofficeknowledgegraph-ai/apis.yml: open an issue on github.com/api-evangelist/familyofficeknowledgegraph-ai to ask a question or point us at an artifact you publish.
