OpenAI SDKs

Unless you have a specific requirement, we recommend using the OpenAI request format for every model on Omrouter. It is the easiest format to add to existing applications and makes switching models simpler.

Configuration

Setting	Value
API key	OMROUTER_API_KEY
Base URL	https://omrouter.com/v1
Model	Model name shown on the Pricing page

Python

python -m pip install openai

example.py

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["OMROUTER_API_KEY"],
    base_url="https://omrouter.com/v1",
)

response = client.chat.completions.create(
    model=os.environ["OMROUTER_MODEL_ID"],
    messages=[
        {"role": "user", "content": "Explain what an API gateway does."},
    ],
)

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

JavaScript

npm install openai

example.mjs

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.OMROUTER_API_KEY,
  baseURL: 'https://omrouter.com/v1',
});

const response = await client.chat.completions.create({
  model: process.env.OMROUTER_MODEL_ID,
  messages: [
    { role: 'user', content: 'Explain what an API gateway does.' },
  ],
});

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

Add more features

Start with the simple request above. After it works, add streaming, tools, image input, or JSON output as needed. Model features vary, so test after adding each feature.

If you use an existing client instead of writing code, see Configure existing applications and tools.
