# API reference

> The exhaustive, dry index of every public Smithers export, its signature, params, returns, source, and tests.

This is the API reference: the complete, dry catalog of everything Smithers
exports. Every public function, component, type, and RPC has a page here with its
signature, parameters, return shape, the source and tests that back it, and a
runnable example. Where the **For Humans** and **For Agents** tabs explain why
and walk you through tasks, this tab is the lookup you reach for when you already
know what you want and need the exact shape of it.

## Import map

Almost everything lives behind one facade. Import components, agents, tools,
scorers, memory, openapi, observability, the server/gateway, db, time-travel, and
errors from `smithers-orchestrator`.

```ts theme={null}
import { createSmithers, Task } from "smithers-orchestrator";
```

The browser/React Gateway SDK is the exception: it is published as subpaths so it
can ship independently of the engine and stay client-safe.

* `smithers-orchestrator/gateway-client` · the framework-free RPC/WS client.
* `smithers-orchestrator/gateway-react` · the React hooks and provider built on it.

## How to read a page

Every export follows the same layout, so once you can read one you can read all
of them:

* A one-line summary of what the export does.
* A `ts` signature block - the exact type you call against.
* `ParamField` rows for each parameter and `ResponseField` rows for the return
  shape, with nested `Expandable` blocks for object members.
* A **Throws** note linking the relevant error in [Errors](/reference/errors)
  when the export can fail loud.
* A short, runnable example.
* A footer line: `**Source** · **Tests** · **See also**`, linking the GitHub
  source file, the test file that pins its behavior, and related guides.
