# Core concepts

The Live API is built around a small set of ideas that appear in every resource you create. If you'd rather start hands-on, the [live event walkthrough](/api-guides/how-to/live/walkthrough) covers the same concepts in the context of a working example, and links back here wherever more depth is useful.

## Guides

- [Resource types and lifecycle](/api-guides/how-to/live/core-concepts/resource-types): The four resource types, billing models, the desired state model, and sites.
- [Inputs](/api-guides/how-to/live/core-concepts/inputs): Connecting a live resource to a stream: `sourceName`, `contentName`, `flowName`, refiners, and transform pins.
- [Outputs](/api-guides/how-to/live/core-concepts/outputs): Where encoded output goes: destinations, internal outputs, and the archive asset.
- [Templates](/api-guides/how-to/live/core-concepts/templates): How encoding templates connect to live resources, and the `configValues`/`configOverrides` model.
- [Resource states](/api-guides/how-to/live/core-concepts/resource-states): `spec.state` vs. `status.state`, and what the 13 reported values mean.

## What the Live API depends on

The Live API references two other APIs by name but doesn't manage them directly:

- **Media API**: sources, content, destinations, and assets. See [Content, sources, and destinations](/api-guides/how-to/media/content-and-sources).
- **Templates API**: the encoding and composition templates referenced from your live resources. See [Build with the Templates API](/api-guides/how-to/templates).

## What comes next

- [Live event walkthrough](/api-guides/how-to/live/walkthrough): a complete end-to-end example.
- [Manage live channels and events](/api-guides/how-to/live/manage-live): create and operate liveChannels and liveEvents.
- [Multiview](/api-guides/how-to/live/multiview): compose multiple live inputs into a single output.
