## Machine discovery

Agents and tooling can bootstrap from:

## Auth at a glance

Authenticated endpoints accept an organization API key as a bearer token:

```http theme={null}
Authorization: Bearer $OMNI_API_KEY
```

See [Authentication](/authentication) for scopes, OAuth client credentials, and session rules.
