The Query API is now available on Aura across all tiers and cloud providers for production workloads, allowing users to query Neo4j databases via HTTPS. The new feature uses secure HTTP(S) communications to make Cypher requests with a JSON document response, eliminating the need for drivers or custom libraries. Users can submit simple queries, such as retrieving data from an instance using CURL, and parameterized queries to load bulk data in a single request. The Query API also supports advanced features like transaction management, secure JWT authentication, and performance improvements. With its ease of use, security, and efficiency, the Query API is designed to be an accessible method for working with Neo4j Aura databases.
