Create an account and get keys

Before making any API requests, you must register for a Hirak Exchange Rates account and obtain an API key. This key serves as your primary authentication credential for accessing the API endpoints.

Account Registration

  1. Navigate to the Hirak Exchange Rates official website.
  2. Click on the "Sign Up" or "Get Started Free" button.
  3. Provide the required registration details, typically including an email address and password.
  4. Verify your email address if prompted, which completes the account creation process.

Obtaining Your API Key

After successful registration and login, your API key will be available in your personal dashboard.

  1. Log in to your Hirak Exchange Rates account.
  2. Locate the "API Keys" or "Dashboard" section.
  3. Your unique API key should be displayed. Copy this key, as it will be required for every API request you make.

API keys are sensitive credentials. It is a security best practice to manage them carefully, avoiding exposure in public repositories or client-side code. For server-side applications, environment variables or secure configuration management systems are recommended for storing API keys. The AWS Key Management Service documentation provides an example of secure key management strategies.

Your first request

Once you have an API key, you can make your first request to fetch real-time exchange rates. This example uses the /latest endpoint to retrieve current cryptocurrency to fiat currency rates. The API is RESTful, returning JSON responses.

API Endpoint Structure

The base URL for the Hirak Exchange Rates API is typically https://api.hirak.exchange/. Endpoints are appended to this base URL.

A common endpoint for real-time rates might look like this:

GET https://api.hirak.exchange/latest?access_key=YOUR_API_KEY&symbols=BTC,ETH&base=USD
  • access_key: Your unique API key.
  • symbols: A comma-separated list of cryptocurrency symbols (e.g., BTC, ETH).
  • base: The base currency for the conversion (e.g., USD, EUR).

Example in Python

This Python example uses the requests library to query the /latest endpoint. Ensure you have the requests library installed (pip install requests).

import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.hirak.exchange/"

def get_latest_rates(api_key, symbols, base_currency):
    endpoint = f"{BASE_URL}latest"
    params = {
        "access_key": api_key,
        "symbols": ",".join(symbols),
        "base": base_currency
    }
    try:
        response = requests.get(endpoint, params=params)
        response.raise_for_status()  # Raise an exception for HTTP errors (4xx or 5xx)
        data = response.json()
        print("Successfully fetched rates:")
        print(data)
        return data
    except requests.exceptions.RequestException as e:
        print(f"An error occurred: {e}")
        return None

# Example usage:
symbols_to_fetch = ["BTC", "ETH"]
base = "USD"
latest_rates = get_latest_rates(API_KEY, symbols_to_fetch, base)

if latest_rates and "rates" in latest_rates:
    print(f"Bitcoin (BTC) rate in USD: {latest_rates['rates']['BTC']}")
    print(f"Ethereum (ETH) rate in USD: {latest_rates['rates']['ETH']}")

Example in Node.js

This Node.js example uses the built-in node-fetch (or axios, if preferred and installed) for HTTP requests. For modern Node.js environments, you might need to install node-fetch (npm install node-fetch).

const fetch = require('node-fetch'); // Use require for CommonJS, import for ES Modules

const API_KEY = 'YOUR_API_KEY';
const BASE_URL = 'https://api.hirak.exchange/';

async function getLatestRates(apiKey, symbols, baseCurrency) {
    const symbolsString = symbols.join(',');
    const endpoint = `${BASE_URL}latest?access_key=${apiKey}&symbols=${symbolsString}&base=${baseCurrency}`;

    try {
        const response = await fetch(endpoint);
        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }
        const data = await response.json();
        console.log('Successfully fetched rates:');
        console.log(data);
        return data;
    } catch (error) {
        console.error(`An error occurred: ${error}`);
        return null;
    }
}

// Example usage:
const symbolsToFetch = ['BTC', 'ETH'];
const base = 'USD';
getLatestRates(API_KEY, symbolsToFetch, base).then(latestRates => {
    if (latestRates && latestRates.rates) {
        console.log(`Bitcoin (BTC) rate in USD: ${latestRates.rates.BTC}`);
        console.log(`Ethereum (ETH) rate in USD: ${latestRates.rates.ETH}`);
    }
});

After executing either of these code snippets with a valid API key, you should receive a JSON response containing the requested exchange rates. The structure of the JSON response is detailed in the Hirak Exchange Rates API documentation.

Common next steps

After successfully making your first request, several common next steps can enhance your integration with Hirak Exchange Rates:

  • Explore Additional Endpoints: Beyond real-time rates, Hirak Exchange Rates offers endpoints for historical data and currency conversion. For instance, to retrieve historical data for a specific date, you might use an endpoint like /YYYY-MM-DD.
  • Implement Error Handling: Implement robust error handling to manage rate limits, invalid API keys, and other potential issues that can arise during API calls. The API typically returns HTTP status codes (e.g., 400 for bad request, 401 for unauthorized) and error messages in the JSON response.
  • Integrate SDKs: While the examples above use direct HTTP requests, Hirak Exchange Rates provides official SDKs for Python, Node.js, PHP, Ruby, and Go. These SDKs can simplify integration by abstracting away HTTP request details and providing client libraries tailored to specific languages.
  • Monitor Usage and Upgrade: Keep track of your API usage through your Hirak Exchange Rates dashboard. If your application's demand exceeds the free tier limits (5,000 requests/month), consider upgrading to a paid plan, such as the Starter Plan at $9/month for 50,000 requests/month.
  • Review Security Best Practices: Ensure your API key is kept confidential. Avoid hardcoding it directly into client-side code. For production environments, consider using environment variables or a secrets management service to handle API keys securely. The Google Cloud Secret Manager overview provides insight into managing sensitive data securely.
  • Webhooks for Events: For certain types of financial data, real-time updates via webhooks can be more efficient than polling. While not explicitly stated for all Hirak Exchange Rates features, checking the official documentation for webhook support for specific events is advisable if your use case requires push notifications.

Troubleshooting the first call

If your initial API call to Hirak Exchange Rates fails, consider the following common issues and troubleshooting steps:

  • Invalid API Key: Double-check that you have copied your API key correctly from your Hirak Exchange Rates dashboard. Even minor typos can lead to authentication failures. The API will typically return a 401 Unauthorized status code and an error message indicating an invalid or missing key.
  • Missing Parameters: Ensure all required parameters (e.g., access_key, symbols, base) are included in your request URL and correctly formatted. Consult the specific endpoint documentation to confirm mandatory parameters.
  • Incorrect Endpoint URL: Verify that the base URL and the endpoint path are accurate. For example, ensure you are using https://api.hirak.exchange/latest and not an incorrect variant.
  • Rate Limit Exceeded: If you are on the free tier, you might quickly hit the 5,000 requests/month limit during rapid testing. The API will respond with a 429 Too Many Requests status code. Check your Hirak Exchange Rates dashboard for current usage statistics.
  • Network Issues: Confirm that your development environment has a stable internet connection and no firewall rules are blocking outgoing HTTP requests to api.hirak.exchange. Tools like curl or Postman can help isolate network-related problems outside your code.
  • JSON Parsing Errors: If the API returns a response but your application fails to process it, verify that your JSON parsing logic is correct. Inspect the raw JSON response to ensure it matches the expected structure as described in the Hirak Exchange Rates API documentation. An online JSON validator can help identify syntax issues if you copy the raw response.
  • HTTP Method Mismatch: Most Hirak Exchange Rates data retrieval endpoints use the GET HTTP method. Ensure your client is making a GET request, not POST or another method, unless otherwise specified in the documentation. The HTTP/1.1 Semantics and Content RFC for GET describes its use for data retrieval.
  • Unsupported Symbols or Base Currencies: Check if the cryptocurrency symbols (e.g., BTC, ETH) and base currencies (e.g., USD, EUR) you are requesting are supported by the API. The API documentation typically includes a list of supported currencies.

By systematically checking these points, you can often diagnose and resolve issues with your initial Hirak Exchange Rates API integration efficiently.
