## Chapter 18. REST API

The Neo4j REST API is designed with discoverability in mind, so that you can start with a `GET` on the Section 18.1, “Service root” and from there discover URIs to perform other requests. The examples below uses URIs in the examples; they are subject to change in the future, so for future-proofness discover URIs where possible, instead of relying on the current layout. The default representation is json, both for responses and for data sent with `POST`/`PUT` requests.

Below follows a listing of ways to interact with the REST API. For language bindings to the REST API, see Chapter 5, Neo4j Remote Client Libraries.

To interact with the JSON interface you must explicitly set the request header `Accept:application/json` for those requests that responds with data. You should also set the header `Content-Type:application/json` if your request sends data, for example when you’re creating a relationship. The examples include the relevant request and response headers.

The server supports streaming results, with better performance and lower memory overhead. See Section 18.2, “Streaming” for more information.
