Global Exchange Rates

A Python client library for interacting with the Global Exchange Rates API.

It provides a set of methods for retrieving exchange rates, currency and providers information, and converting amounts between currencies.

Global Exchange Rates API

The Global Exchange Rates API provides a simple and reliable way to download official exchange rates from central banks and tax authorities (providers) worldwide.

You can check the updated list from the official website.

Daily exchange rates of all the available currencies are also provided, calculated using a proprietary algorithm blending the official data from central banks and the market rate from commercial institutions.

Ideal for accounting, CRM and ERP systems, business intelligence, auditing, tax compliance and reporting.

Getting Started

• Sign up to the Developer API Portal and start the 30 day free trial.
• Get your API key.
• Install:

Usage

Synchronous API

from global_exchange_rates import GlobalExchangeRates, ApiException

# Initialize the client
client = GlobalExchangeRates(api_key="your_api_key")

try:
    # Get all currencies
    currencies = client.get_currencies()
    print(f"Got {len(currencies)} currencies")
    
    # Get specific currencies
    eur_usd = client.get_currencies(codes=["EUR", "USD"])
    print(f"EUR: {eur_usd[0].name}, USD: {eur_usd[1].name}")
    
    # Get latest exchange rates
    rates = client.get_latest(
        base_currency="EUR", 
        currencies=["USD", "GBP", "JPY"]
    )
    print(f"1 EUR = {rates.exchange_rates['USD']} USD")
    
    # Get historical exchange rates
    from datetime import date
    historical = client.get_historical(
        date_value=date(2025, 1, 1),
        base_currency="EUR",
        currencies=["USD", "GBP"]
    )
    print(f"1 EUR = {historical.exchange_rates['USD']} USD on Jan 1, 2025")
    
    # Convert currency
    conversion = client.convert(
        amount=100.0,
        base_currency="EUR",
        to_currencies=["USD", "GBP"]
    )
    print(f"€100 = ${conversion.conversions['USD']:.2f}")
    
    # Get providers
    providers = client.get_providers()
    for provider in providers:
        print(f"Provider: {provider.code} ({provider.description})")
    
except ApiException as e:
    print(f"API Error: {e}")

Asynchronous API

import asyncio
from global_exchange_rates import GlobalExchangeRates, ApiException

async def main():
    # Use as async context manager
    async with GlobalExchangeRates(api_key="your_api_key") as client:
        try:
            # Get all currencies
            currencies = await client._get_currencies_async()
            print(f"Got {len(currencies)} currencies")
            
            # Get latest exchange rates
            rates = await client._get_latest_async(
                base_currency="EUR", 
                currencies=["USD", "GBP", "JPY"]
            )
            print(f"1 EUR = {rates.exchange_rates['USD']} USD")
            
            # Get historical exchange rates
            from datetime import date
            historical = await client._get_historical_async(
                date_value=date(2025, 1, 1),
                base_currency="EUR",
                currencies=["USD", "GBP"]
            )
            print(f"1 EUR = {historical.exchange_rates['USD']} USD on Jan 1, 2025")
            
            # Convert currency
            conversion = await client._convert_async(
                amount=100.0,
                base_currency="EUR",
                to_currencies=["USD"]
            )
            print(f"€100 = ${conversion.conversions['USD']:.2f}")
            
        except ApiException as e:
            print(f"API Error: {e}")

# Run the async function
asyncio.run(main())

Error Handling

The client raises ApiException when an API error occurs. This exception contains:

• status_code: HTTP status code
• error_code: API-specific error code (if available from the API)
• api_message: Error message from the API (if available)

try:
    currencies = client.get_currencies()
except ApiException as e:
    print(f"Error message: {str(e)}")
    print(f"HTTP Status: {e.status_code}")
    if e.error_code:
        print(f"Error Code: {e.error_code}")
    if e.api_message:
        print(f"API Message: {e.api_message}")
