5-minute Quickstart

From signup to your first API call in five minutes.

1. Sign up on RapidAPI

Visit our RapidAPI organization and create a free account if you don't already have one. RapidAPI handles authentication and billing for all 20 Helix-APIs through a single dashboard.

2. Subscribe to an API

Pick any API from our catalog (let's use QR Code as the simplest). Click the Subscribe button on the Basic plan — it's free, no credit card required.

3. Copy your API key

Your X-RapidAPI-Key appears on the right side of the API listing page. Copy it — you'll need it in step 4.

4. Make your first request

Open a terminal and run the curl command below. You should get a healthy response in under a second.

bash

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

5. Try a real endpoint

Replace /health with /generate?data=hello to actually generate a QR code. The same pattern works for every endpoint across every Helix-API service.
