Neo4j REST API

Native graph database with powerful Cypher query language

Neo4j is a high-performance native graph database that stores data as nodes and relationships rather than tables. Developers use Neo4j's REST API to execute Cypher queries, manage graph data structures, and build applications requiring complex relationship traversal, recommendation engines, fraud detection, and knowledge graphs. It excels at handling connected data scenarios where traditional relational databases struggle.
