# Installation

> Install the typed Syvon client SDK. Zero runtime dependencies, runs on Node 18+, browsers, Deno, Bun, and Cloudflare Workers.

```bash theme={null}
npm install @syvon/sdk
```

Or with pnpm / yarn / bun:

```bash theme={null}
pnpm add @syvon/sdk
```

## Requirements

* A `fetch` implementation. Node 18+, all modern browsers, Deno, Bun, and Cloudflare Workers ship one. On older Node, pass a polyfill via `fetchImpl`.
* One or both credentials, depending on which surfaces you use (see [Authentication](/authentication)).

## Verify

```ts theme={null}
import { SyvonClient } from '@syvon/sdk';

const client = new SyvonClient({ workspaceKey: process.env.SYVON_WS_KEY! });
console.log(await client.brain.whoami());
```

## TypeScript

The package ships its own `.d.ts` types. All response types are exported from the package root, so you can type your own state directly:

```ts theme={null}
import type { FeedPost, AgentItem } from '@syvon/sdk';
```

See [Types](/sdk/types) for the full export list.
