Getting Started with Helix-API: Your First API Call in 60 Seconds

Welcome to Helix-API. This guide will get you from zero to your first successful API call in about a minute.

Step 1: Get an API key

Head to our RapidAPI organization and pick any API. Click Subscribe on the Basic tier — it's free, no credit card required.

Your API key appears in the right sidebar. Copy it; you'll need it in step 3.

Step 2: Pick an endpoint

Every Helix-API service has a /health endpoint that returns instantly. We'll use that for the quickest possible "hello world".

For the QR Code API, the URL is: https://qr-code-by-helix-api.p.rapidapi.com/health

Step 3: Make the call

Open a terminal and run:

curl -X GET "https://qr-code-by-helix-api.p.rapidapi.com/health" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: qr-code-by-helix-api.p.rapidapi.com"

You should see:

{
  "status": "ok",
  "service": "qr-code",
  "brand": "Helix-API"
}

That's it. The pattern is the same for all 20 APIs — just change the host and endpoint.
