Graph Playground API

What you can explore

The playground is for multifaceted connections across Knowledge Graph V2, not entity dumps. Starter chips (loaded from the meta endpoint) include Alzheimer facet chains, 4–6 hop walks, and variable-length paths. Use the live Graph Playground to run them.

UI

Open Graph Playground: use Test drive our APIs for public endpoints, or the Cypher editor for connection queries. Shortcut: Ctrl/⌘ + Enter.

Endpoints

GET /api/playground/meta

Labels, edge types, starter connection queries, graph totals (Redis fresh + stale). Host: https://api.care-intel.net.

POST /api/playground/query

{
  "cypher": "MATCH (d:Disease)-[:ASSOCIATED_WITH]->(g:Gene) WHERE … RETURN … LIMIT 20",
  "limit": 20
}

Full starter Cypher ships from /api/playground/meta; it is not duplicated in this page.
