# OpenAI Node SDK with Zurelay

> Official OpenAI library for TypeScript and JS. Made by OpenAI.

Source: https://zurelay.com/docs/integrations/openai-node

The examples use `claude-opus-5-5`. Any model ID from [the models page](https://zurelay.com/docs/models) works.

## Set it up

1. Install the SDK: `npm install openai`.
2. Create the client with Zurelay’s base URL and your key.
3. Call any chat model in the catalog by its ID. Streaming, tools and JSON mode work as usual.

## Configuration

**Chat** (`app.ts`):

```typescript
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.zurelay.com/v1",
  apiKey: process.env.ZURELAY_API_KEY,
});

const completion = await client.chat.completions.create({
  model: "claude-opus-5-5",
  messages: [{ role: "user", content: "Hello" }],
});

console.log(completion.choices[0]?.message.content);
```

**Images** (`image.ts`):

```typescript
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.zurelay.com/v1",
  apiKey: process.env.ZURELAY_API_KEY,
});

const result = await client.images.generate({
  model: "nano-banana-pro",
  prompt: "A glass prism splitting white light into a rainbow",
  n: 1,
});

console.log(result.data?.[0]?.url);
```

> **Note:** The SDK also reads `OPENAI_BASE_URL` and `OPENAI_API_KEY`, so existing code can switch with two environment variables.
