# OpenAI SDK (Node.js)

[Markdown](https://ailoot.ai/docs/en/integrations/openai-node-js-sdk/index.md)

SDK · OpenAI Chat, OpenAI Responses

| Format | Where to set it up |
| --- | --- |
| OpenAI Chat, OpenAI Responses | Constructor option new OpenAI({ baseURL, apiKey }); the SDK reads OPENAI\_BASE\_URL by default |

## [](https://ailoot.ai/docs/en/integrations/openai-node-js-sdk/#setup)Setup

Copy the configuration and replace `sk-...` with your key from the Ailoot Dashboard. Prefer storing the key in the environment variable `AILOOT_API_KEY`, if the application supports it.

Before starting, request GET /v1/models with your Ailoot key. Choose an exact model ID whose methods include POST /v1/chat/completions, POST /v1/responses, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.

```js
import OpenAI from "openai";
const client = new OpenAI({maxRetries: 0,
  baseURL: "https://api.ailoot.ai/v1",
  apiKey: process.env.AILOOT_API_KEY // sk-...
});
const r = await client.chat.completions.create({
  model: "claude-sonnet-5-5",
  messages: [{ role: "user", content: "Hello" }]
});
console.log(r.choices[0].message.content);
```

This configuration reads the key from the environment variable `AILOOT_API_KEY`. Set it before starting the application:

```bash
export AILOOT_API_KEY="sk-..."   # add to ~/.zshrc or ~/.bashrc
```

```powershell
setx AILOOT_API_KEY "sk-..."   # then restart the terminal
```

Example model: `claude-sonnet-5-5, gpt-6.1-sol, grok-4.7`. Choose any other model from the [catalog](https://ailoot.ai/models/en/) — check that it supports the format you need.

## [](https://ailoot.ai/docs/en/integrations/openai-node-js-sdk/#notes)Good to know

The README shows baseURL. Reading OPENAI\_BASE\_URL is visible in the client source, src/client.ts; its default is https://api.openai.com/v1. Include /v1 in the Ailoot URL. Both chat.completions and responses are available.

## [](https://ailoot.ai/docs/en/integrations/openai-node-js-sdk/#check)Test

- For the OpenAI format, the URL is `https://api.ailoot.ai/v1` (or the full path if the application asks for a full URL).
- Ask a short question. If you get an error, check the code and Request ID, then consult [Errors and limits](https://ailoot.ai/docs/en/errors/).
- 404 immediately after setup almost always means the URL is wrong: an extra or missing `/v1`.
- 402 — insufficient balance for the reserve. Agents reserve more than chat: [why](https://ailoot.ai/docs/en/billing/reserve/).
