Obtaining an API Key
Obtaining an API key is the first step in using the Fixer.io forex rates API. For this, let’s sign up for one of the paid plans it offers. We can view the API key we obtained from the ‘Dashboard’ page with API usage information.
Code
In this section, we will write the code for an application that pulls the exchange rates of certain currencies using the Fixer.io API with Python and prints the response to the console.
For this application, we will use the requests library. This library allows us to make HTTP requests easily. To install the library, let’s run the following command in the terminal:
|
1 |
pip install requests |
Then, let’s put the Python code that sends a request to the Fixer.io API, processes the response, and prints the results to the console into a Python file:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |
import requests import json # Enter your API access key here API_KEY = 'YOUR_API_KEY' # API endpoint and parameters url = 'https://data.fixer.io/api/latest' params = { 'access_key': API_KEY, 'base': 'USD', 'symbols': 'GBP,JPY,EUR' } # Make the API request response = requests.get(url, params=params) # Parse the response in JSON format data = response.json() # Print the fields in the JSON response to the console if data['success']: print(f"Success: {data['success']}") print(f"Timestamp: {data['timestamp']}") print(f"Base: {data['base']}") print(f"Date: {data['date']}") print("Rates:") for currency, rate in data['rates'].items(): print(f" {currency}: {rate}") else: print("Failed to fetch data") print(f"Error: {data['error']['info']}") |
Before running the application, let’s enter our Fixer.io API key into the API_KEY variable.
Test
To run the code, let’s save our file (for example, as fixer_api.py) and run the following command in the terminal:
|
1 |
python fixer_api.py |
When we follow these steps, we will create an application that gets the exchange rates of the currencies we specify from the Fixer.io API and prints them to the console. The response we get after running the application is as follows:
|
1 2 3 4 5 6 7 8 |
Success: true Timestamp: 1519296206 Base: USD Date: 2024-07-18 Rates: GBP: 0.72007 JPY: 107.346001 EUR: 0.813399 |
Advanced API Usage
Accessing Historical Exchange Rates
Fixer.io API provides features that allow you to retrieve exchange rate data for a specific date. This feature is very useful for analyzing exchange rate trends or financial reporting. To query historical data, we can use the historical endpoint to retrieve exchange rates for a specific date.
Sample code snippet:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
import requests import json # Enter your API access key here API_KEY = 'YOUR_API_KEY' # Getting exchange rate data for a specific date date = '2023-07-01' url = f'https://data.fixer.io/api/{date}' params = { 'access_key': API_KEY, 'base': 'USD', 'symbols': 'GBP,JPY,EUR' } response = requests.get(url, params=params) data = response.json() if data['success']: print(f"Success: {data['success']}") print(f"Base: {data['base']}") print(f"Date: {data['date']}") print("Rates:") for currency, rate in data['rates'].items(): print(f" {currency}: {rate}") else: print("Failed to fetch data") print(f"Error: {data['error']['info']}") |
Processing Large Datasets
Efficiently processing large volumes of exchange rate data is important for performance and data integrity. One of the best ways to process data is to divide it into chunks and make the processing asynchronous. We can process large datasets efficiently using the pandas and asyncio libraries in Python.
Sample code snippet:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
import requests import pandas as pd import asyncio import aiohttp API_KEY = 'YOUR_API_KEY' BASE_URL = 'https://data.fixer.io/api/' CURRENCIES = 'GBP,JPY,EUR' async def fetch_rate(session, date): url = f'{BASE_URL}{date}' params = { 'access_key': API_KEY, 'base': 'USD', 'symbols': CURRENCIES } async with session.get(url, params=params) as response: return await response.json() async def main(dates): async with aiohttp.ClientSession() as session: tasks = [fetch_rate(session, date) for date in dates] return await asyncio.gather(*tasks) dates = ['2023-07-01', '2023-07-02', '2023-07-03'] loop = asyncio.get_event_loop() results = loop.run_until_complete(main(dates)) df = pd.DataFrame(results) print(df) |
Automate Currency Conversion
Automating currency conversion using the Fixer.io API is pretty straightforward. We can use the convert endpoint to convert a specific amount to the desired currency. Below is a sample code to automate currency conversion.
Sample code snippet:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
import requests API_KEY = 'YOUR_API_KEY' BASE_URL = 'https://data.fixer.io/api/convert' def convert_currency(amount, from_currency, to_currency): params = { 'access_key': API_KEY, 'from': from_currency, 'to': to_currency, 'amount': amount } response = requests.get(BASE_URL, params=params) data = response.json() if data['success']: return data['result'] else: print(f"Error: {data['error']['info']}") return None amount = 100 from_currency = 'USD' to_currency = 'EUR' result = convert_currency(amount, from_currency, to_currency) if result: print(f"{amount} {from_currency} is equal to {result} {to_currency}") |
This code converts a given amount from one currency to another and prints the result to the console. We can use the schedule library to schedule automatic conversions.
Example schedule:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import schedule import time def job(): result = convert_currency(100, 'USD', 'EUR') if result: print(f"Scheduled Conversion: 100 USD is equal to {result} EUR") schedule.every().day.at("10:30").do(job) while True: schedule.run_pending() time.sleep(1) |

Best Practices for Using Fixer.io API
Security Considerations
When using the Fixer.io API, it is very important to secure your API keys and data. API keys should be kept secret to prevent unauthorized access. These keys should only be accessible by authorized users and applications. We can use secure online storage services or encryption techniques to store keys. For example, instead of storing API keys directly in the source code, we can increase their security by using environment variables or secure configuration files.
Optimizing API Calls
There are some tips to reduce latency and improve response times when using the Fixer.io API. First, to avoid unnecessary API calls, we should specify the data we need in advance and send requests only with the necessary parameters. For example, when querying exchange rates for specific currencies, we should throttle our request by specifying only the currencies we need, not all currencies.
Rate limiting is another important aspect of optimizing API usage and maintaining quality of service. API providers usually limit the maximum number of requests that can be made in a given time period. To meet these limits, we need to schedule our requests and control the frequency of requests. Additionally, caching response data can improve performance by reducing the number of repeated requests.
We can also use asynchronous programming techniques for efficient API usage. This can help reduce response times by making multiple API requests at the same time.
