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.com.

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 — not duplicated in this page.
