# Overview

> Detailed API reference map for ByteKit public modules.

## What this tab covers

This tab breaks down the public ByteKit API by module family.

* Core HTTP and request types
* Resilience and request control primitives
* Async utilities
* Observability modules
* Helper modules exposed through focused entrypoints

## How to use this section

* Start with [HTTP client](/api-reference/http-client) if your app centers around API requests.
* Start with [Resilience](/api-reference/resilience) if you need retries, caching, or throttling.
* Start with [Async](/api-reference/async) if you only need flow-control utilities.
* Start with [Helpers](/api-reference/helpers) if you need the rest of the utility surface.

  This section documents public package modules and the intended purpose of each export. It is not generated from TypeDoc, so examples stay editorial and task-focused.
