# API Reference

> Base URL, authentication, and endpoint reference for the Noonum REST API.

The Noonum REST API lets you build, submit, and manage [thematic investment strategies](/base/concepts/overview), browse [premade strategies](/v1/guides/overview), run semantic search, and [back-test](/v1/guides/rest-integration) portfolios.

## Base URL

All endpoints are served under:

```text theme={null}
https://api.noonum.ai/v1
```

## Authentication

Every request must include a bearer token:

```text theme={null}
Authorization: Bearer <token>
```

The token is your Noonum API key. See [Authentication](/v1/getting-started/authentication) for how to request a key.

## Using this reference

The endpoints in the sidebar are generated from the live OpenAPI spec. Each page documents the request and response schema and includes an interactive console.

Open any endpoint to send a request from the console, or start with the Strategies endpoints to build and back-test your first strategy.
