# API Reference

> Getting started with SafeDep API

SafeDep supports a [gRPC](https://grpc.io/) API with
a [ConnectRPC](https://connectrpc.com/) facade allowing clients to use both
gRPC over HTTP/2 and JSON over HTTP/1.1 based clients.

Authentication uses [OAuth 2.0](https://oauth.net/2/) or API keys, depending on the plane:

* Control plane APIs (e.g. creating policy) require OAuth 2.0 authentication.
* Data plane APIs (e.g. getting policy data) accept API keys.

Control plane APIs are for management tooling; data plane APIs are for security tools that use or integrate with SafeDep.
