# List graph — GET /v1/knowledge/graph

URL: https://docs.hanzo.ai/docs/openapi/knowledge/get-knowledge-graph

> Returns the caller org's knowledge as a node/edge graph shaped for a force-directed renderer: pages, memories and synced sources as nodes; the page parent tree, the wikilinks between pages, and each source's connector provenance as edges.

| **Address**   | `https://api.hanzo.ai/v1/knowledge/graph` |
| **Method**    | `GET`                                     |
| **Operation** | `get_knowledge_graph`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`    |

Returns the caller org's knowledge as a node/edge graph
shaped for a force-directed renderer: pages, memories and synced sources as
nodes; the page parent tree, the wikilinks between pages, and each source's
connector provenance as edges. Wikilink targets are resolved HERE by title or
slug, so a rename never needs an edge rewrite and a link that matches no page
renders as its own "unresolved" node instead of vanishing. ?project= narrows
it. A store outage degrades to an honest empty graph, never a 5xx.

| `degraded`        | body | boolean                | —      | Degraded is true when the store was unreachable and this graph is honestly empty rather than wrong.                                                                  |
