Manual Installation

1. Download or clone this repository
2. Install dependencies: pip install requests
3. Import the library

from src import FcsApi

Quick Start

from src import FcsApi

fcsapi = FcsApi()

# Forex
response = fcsapi.forex.get_latest_price('EURUSD')

# Crypto
response = fcsapi.crypto.get_latest_price('BINANCE:BTCUSDT')

# Stock
response = fcsapi.stock.get_latest_price('NASDAQ:AAPL')

Usage Examples

Example 1: Simple Price Check

from src import FcsApi

fcsapi = FcsApi()

# Get EUR/USD price
response = fcsapi.forex.get_latest_price('EURUSD')

if fcsapi.is_success():
    data = response['response'][0]
    print(f"EUR/USD: {data['active']['c']}")
    print(f"Change: {data['active']['chp']}%")
else:
    print(f"Error: {fcsapi.get_error()}")

Example 2: Currency Converter

from src import FcsApi

fcsapi = FcsApi()

# Forex: Convert 1000 EUR to USD
response = fcsapi.forex.convert('EUR', 'USD', 1000)
if fcsapi.is_success():
    data = response['response']
    print(f"1000 EUR = {data['total']} USD")

# Crypto: Convert 1 BTC to USD
response = fcsapi.crypto.convert('BTC', 'USD', 1)
if fcsapi.is_success():
    data = response['response']
    print(f"1 BTC = ${data['total']:,.2f} USD")

Example 3: Multiple Symbols with Error Handling

from src import FcsApi

fcsapi = FcsApi()

# Get multiple forex pairs
symbols = ['EURUSD', 'GBPUSD', 'USDJPY']
response = fcsapi.forex.get_latest_price(','.join(symbols))

if fcsapi.is_success():
    for item in response['response']:
        symbol = item['ticker']
        price = item['active']['c']
        change = item['active']['chp']
        print(f"{symbol}: {price} ({change}%)")
else:
    print(f"Error: {fcsapi.get_error()}")

Authentication Methods

The library supports 4 authentication methods for different security needs:

Method 1: Default Configuration (Recommended)

Set your API key once in src/fcs_config.py:

self.access_key = 'YOUR_API_KEY_HERE'

Then simply use:

fcsapi = FcsApi()

Method 2: Direct API Key

Pass API key directly (overrides config):

fcsapi = FcsApi('YOUR_API_KEY')

Method 3: IP Whitelist (No Key Required)

Whitelist your server IP at FCS Dashboard:

from src import FcsConfig

config = FcsConfig.with_ip_whitelist()
fcsapi = FcsApi(config)

Method 4: Token-Based Authentication (Secure for Frontend)

Generate secure tokens on backend, use on frontend without exposing API key:

from src import FcsConfig

# Backend: Generate token
config = FcsConfig.with_token('YOUR_API_KEY', 'YOUR_PUBLIC_KEY', 3600)
fcsapi = FcsApi(config)
token_data = fcsapi.generate_token()
# Returns: {'_token': '...', '_expiry': 1234567890, '_public_key': '...'}

# Send token_data to frontend for secure API calls

Token Expiry Options:
