SDKs and libraries

The simplest LLM.kiwi clients are the OpenAI Python and JavaScript packages configured with the custom chat completions base URL.

Compatibility applies to the endpoints and fields documented by LLM.kiwi. A library may expose additional OpenAI features that LLM.kiwi does not support.

Python

Install:

python -m pip install openai

Configure:

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.llm.kiwi/v1",
    api_key=os.environ["LLM_KIWI_API_KEY"],
)

response = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "Hello!"}],
)

print(response.choices[0].message.content)

JavaScript and TypeScript

Install:

npm install openai

Configure in server-side code:

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.llm.kiwi/v1",
  apiKey: process.env.LLM_KIWI_API_KEY,
});

const response = await client.chat.completions.create({
  model: "auto",
  messages: [{ role: "user", content: "Hello!" }],
});

console.log(response.choices[0].message.content);

Do not initialize a private API client in browser-side React, Vue, Svelte, or plain JavaScript. Send browser requests to your own backend, then call LLM.kiwi from that backend.

Direct HTTP

You do not need an SDK. Any server-side HTTP client can call the API.

curl "https://api.llm.kiwi/v1/chat/completions" \
  -H "Authorization: Bearer $LLM_KIWI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "auto",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

A direct HTTP client is useful when:

Your language has no maintained OpenAI-compatible SDK.
You want minimal dependencies.
You need precise control over timeouts, retries, or streaming.

Other clients and frameworks

Before using a community library, confirm that it lets you configure all three items:

Base URL: https://api.llm.kiwi/v1
Bearer API key
Chat completions model name such as auto

Frameworks may change their configuration names between versions. Follow the framework’s current documentation and verify the generated request against the API reference.

Which option should I choose?

Your project	Recommended starting point
Python backend or script	OpenAI Python package
Node.js or TypeScript backend	OpenAI JavaScript package
Another server-side language	Maintained OpenAI-compatible client or direct HTTP
Browser or mobile interface	Your own backend proxy; never embed the key
Learning the API itself	cURL or direct HTTP
