Graph Playground API

What you can explore

The playground is for connections, not entity dumps. Starter queries include breast-cancer trials conducted at Ohio hospitals, genes associated with Alzheimer’s disease, Maryland clinical investigators (KOLs), and drugs indicated for type 2 diabetes mellitus.

UI

Open Graph Playground: write Cypher on the left, inspect Table / JSON on the right. Starter chips load connection queries into the editor. Shortcut: Ctrl/⌘ + Enter.

Endpoints

GET https://api.care-intel.com/api/playground/meta

Labels, edge types, starter connection queries, graph totals (Redis fresh + stale).

POST https://api.care-intel.com/api/playground/query

{
  "cypher": "MATCH (drug:Drug)-[:INDICATED_FOR]->(d:Disease)\nWHERE toLower(coalesce(d.name,\"\")) CONTAINS \"type 2 diabetes\"\nRETURN coalesce(drug.name, drug.drug_name) AS drug, d.name AS disease\nLIMIT 20"
}

Rules

• Read-only: MATCH / WITH / RETURN only.
• Hard cap of 50 rows; server enforces LIMIT.
• Responses cached in Redis so the sandbox stays available under graph load.
