Neo4j Query API
The Neo4j Query API enables the execution of Cypher statements against a Neo4j server through HTTP requests. It provides a streamlined interface for running graph database queries, supporting both self-managed and cloud-hosted Neo4j instances. The Query API is designed for applications that need to interact with Neo4j programmatically and is particularly useful for languages where a dedicated Neo4j driver is not available.
