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.

Neo4j Query API is one of 12 APIs that Neo4j publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Graph Database, Cypher, Query, HTTP, and Database. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

This API exposes 1 operation across 1 path, and defines 9 schemas. It is described by OpenAPI 3.2.0, at version 5.0.

Requests are made against 2 base URLs: http://localhost:7474, https://localhost:7473.

Where this information came from

This is an independent, third-party profile of Neo4j Query API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
