Quickstart

Create an API key and make your first request in a few minutes.

CLI

Install the terminal client, sign in and run Nebula against an authorized target.

Security

How keys, tenants, stored data and streams are protected.

Changelog

Dated changes to the API, the documentation and the version lifecycle.

Your first request

The LLM API speaks the OpenAI wire format, so existing SDKs work by changing the base URL. Keep the key in an environment variable, never in code.
