# Infra — SDK quickstart

07 / INFRA · SDK QUICKSTART

The SDK (`@signum-tech/sdk`) is generated from the Clossir OpenAPI spec. Commands return
`202 Accepted` (processed asynchronously); reads return `200`. All calls are
authenticated with an org-scoped API key.

## Install

```bash title="Install"
npm install @signum-tech/sdk
```

## First call

```ts title="quickstart.ts"
import { SignumClient } from "@signum-tech/sdk";

const signum = new SignumClient({ apiKey: process.env.SIGNUM_API_KEY });

// Reads return 200
const asset = await signum.assets.get({ id: "ast_123" });

// Commands return 202 — poll the GET endpoint for the result
await signum.identity.parties.create({ /* … */ });
```

The exact client shape is generated from the OpenAPI specification once it's wired.
