2.Subscribe to the Currency Exchange API (free tier available)
3.Copy your X-RapidAPI-Key from the dashboard

Complete Ruby Example

helix-currency-exchange.rb

require "httparty"
require "json"

url = "https://currency-exchange-by-helix-api.p.rapidapi.com/latest?base=USD"
headers = {
  "X-RapidAPI-Key" => "YOUR_API_KEY",
  "X-RapidAPI-Host" => "currency-exchange-by-helix-api.p.rapidapi.com"
}

response = HTTParty.get(url, headers: headers)
data = JSON.parse(response.body)

puts "Status: #{data['status']}"
puts "Result: #{data['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
