🐍 Python ⚡ JavaScript 🔗 cURL 🐘 PHP 💎 Ruby 🔵 Go ☕ Java 🟣 C#

Prerequisites

1.Sign up for a free account on RapidAPI
2.Subscribe to the URL Shortener API (free tier available)
3.Copy your X-RapidAPI-Key from the dashboard
4.Install the dependency: npm install node-fetch

Complete JavaScript Example

helix-url-shortener.js

const url = "https://url-shortener-by-helix-api.p.rapidapi.com/shorten";

const response = await fetch(url, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-RapidAPI-Key": "YOUR_API_KEY",
    "X-RapidAPI-Host": "url-shortener-by-helix-api.p.rapidapi.com"
  },
  body: JSON.stringify({"url": "https://helix-api.com/apis"})
});

const { status, data } = await response.json();
console.log("Status:", status);
console.log("Result:", data);

Response Format

All Helix-API endpoints return a consistent JSON envelope:

{
  "status": "ok",
  "data": { ... },
  "meta": {
    "request_id": "req_abc123",
    "latency_ms": 42
  }
}

On errors, status becomes "error" and a message field explains what went wrong.

Error Handling

Status	Meaning	Action
`200`	Success	Parse the response body normally
`400`	Bad request	Check your request parameters
`401`	Unauthorized	Verify your X-RapidAPI-Key header
`429`	Rate limited	Wait and retry with exponential backoff
`500`	Server error	Retry after a short delay

JavaScript Best Practices

Works in Node.js and the browser

The fetch API works everywhere. In Node.js 18+, fetch is built-in — no packages needed to call the URL Shortener API.

TypeScript types for safety

Define an interface for the API response. This gives you autocomplete and catches bugs at compile time.

AbortController for timeouts

Wrap your fetch call with an AbortController to set a timeout. This prevents your app from hanging on slow responses.

Cache responses when possible

Use a Map or Redis to cache responses for deterministic endpoints. This reduces API calls and speeds up your app.
