Portrix Quickstart: Make Your First AI API Request

This page walks you through sending your first AI request via Portrix. By the end, you’ll have a working API call that routes through the Portrix gateway to any model in the catalog — all using the same OpenAI SDK you may already have installed.

Prerequisites

Before you start, make sure you have:

A Portrix account — sign up for free at app.portrix.ai
Basic familiarity with REST APIs or the OpenAI SDK in Python or TypeScript

Your existing OpenAI code works — just change the base URL and use a Portrix API key.

Steps

Create your account

Go to app.portrix.ai and sign up for a free account. After you verify your email and complete onboarding, you’ll land in the Portrix dashboard. Your API keys are under Settings → API Keys in the left sidebar.

Get your API key

In the dashboard, navigate to Settings → API Keys and click Create new key. Give your key a descriptive label (for example, development or my-app-prod), then click Create. Copy the key immediately — it’s shown only once. Store it somewhere safe, such as a password manager or secrets vault.

Install the SDK

Portrix is OpenAI-compatible, so you use the standard openai package. Install it with your preferred package manager:

npm install openai

yarn add openai

pnpm add openai

pip install openai

Send your first request

Point the OpenAI SDK at the Portrix base URL and use your Portrix API key. Then choose any model from the catalog using the provider/model-name format.

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_PORTRIX_API_KEY",
    base_url="https://api.portrix.ai/v1",
)

response = client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[
        {"role": "user", "content": "Explain what Portrix does in one sentence."}
    ],
)

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

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_PORTRIX_API_KEY",
  baseURL: "https://api.portrix.ai/v1",
});

const response = await client.chat.completions.create({
  model: "openai/gpt-4o",
  messages: [
    { role: "user", content: "Explain what Portrix does in one sentence." },
  ],
});

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

Run the code and you should see a response printed to your terminal. That request traveled through the Portrix gateway and was routed to OpenAI’s GPT-4o on your behalf.

Explore models

Now that your integration is working, try swapping the model field to any other model in the Portrix catalog. The rest of your code stays exactly the same.

Python

# Try any of these models — just change the model field
model = "anthropic/claude-3-5-sonnet"
model = "google/gemini-2.0-flash"
model = "mistral/mistral-large-latest"
