Getting Started with FinanceFlowAPI

To get started, you'll need:

Step 1: Fetching Commodity Data

Fetching real-time commodity data is useful for traders and analysts who need up-to-date pricing information. Check out our Commodities Data API for more details.

Endpoint: /commodity-spot

This endpoint retrieves the latest price of a specific commodity.

Request Example:

GET https://financeflowapi.com/api/v1/commodity-spot?api_key=YOUR_API_KEY&name=Coal

Response Example:

{
    "success": true,
    "code": 200,
    "message": "OK",
    "meta": {
        "timestamp": 1740775729,
        "request_id": "67c221313880a"
    },

print(data)

Step 2: Accessing Historical Commodity Data

For trend analysis, you might need historical data. FinanceFlowAPI provides this through the /commodity-history endpoint.

Endpoint: /commodity-history

This endpoint retrieves historical price data for a specific commodity over a given period.

Request Example:

GET https://financeflowapi.com/api/v1/commodity-history?api_key=YOUR_API_KEY&name=Gold&interval=day&date_from=2025-01-01&date_to=2025-01-31

    "code": 200,
    "message": "OK",
    "meta": {
        "timestamp": 1740776956,

response = requests.get(url)
data = response.json()

df = pd.DataFrame(data['data'])
print(df)

Step 3: Tracking Government Bond Yields

Government bond yields matter to investors and analysts. FinanceFlowAPI provides real-time and historical data on government bonds. Learn more about types of government bonds.

Endpoint: /bonds-spot

data = response.json()

print(data)

Step 5: Working with Stock Tickers via FinanceFlowAPI

FinanceFlowAPI gives you access to real-time stock ticker data across 511,000+ global tickers. Our Stock Ticker API works for traders, developers, and analysts who need financial market data. Check our Stock Index API for index-related data.

With the same Stock Ticker API, you can retrieve both metadata and live prices for companies like AAPL, TSLA, and GOOGL. It has two endpoints:

Endpoint: /tickers-catalog (Tickers Data API)

This endpoint returns structured metadata for thousands of tickers. Use it to explore available instruments filtered by exchange or ticker symbol, a good starting point for building your own ticker database with the FinanceFlowAPI Ticker API.

Request Examples:

GET https://financeflowapi.com/api/v1/tickers-catalog?api_key=YOUR_API_KEY
GET https://financeflowapi.com/api/v1/tickers-catalog?api_key=YOUR_API_KEY&exchange=NYSE
GET https://financeflowapi.com/api/v1/tickers-catalog?api_key=YOUR_API_KEY&ticker=GOOGL

Response Example:

{
    "success": true,
    "code": 200,
    "message": "OK",
    "meta": {
        "page": 1,
        "total_pages": 2,
        "total_items": 425,
        "tickers_per_page": 300,
        "timestamp": 1745423861,
        "request_id": "68090df504b96"
    },
    "data": [
        {
            "ticker": "TOPS",
            "company_name": "Top Ships Inc.",
            "exchange": "ASE",
            "full_exchange_name": "NYSE American",
            "currency": "USD",
            "market": "us_market",
            "first_trade_date": "2004-08-02 13:30:00",
            "timezone": "America/New_York"
        }
    ]
}

Python Example:

import requests

API_KEY = 'your_api_key_here'
url = f'https://financeflowapi.com/api/v1/tickers-catalog?api_key={API_KEY}&exchange=NASDAQ'

response = requests.get(url)
data = response.json()

for ticker in data['data']:
    print(ticker['ticker'], ticker['company_name'])

Endpoint: /ticker-spot (Real-Time Stock Ticker API)

This endpoint provides real-time stock ticker data for a single symbol. It's a core feature of our financial data API that powers dashboards, trading bots, and mobile finance apps.

Request Example:

GET https://financeflowapi.com/api/v1/ticker-spot?api_key=YOUR_API_KEY&ticker=AAPL

Response Example:

{
    "success": true,
    "code": 200,
    "message": "OK",
    "meta": {
        "timestamp": 1745427151,
        "request_id": "68091acfb967b"
    },
    "data": {
        "ticker": "AAPL",
        "price": "203.890000",
        "change": "4.149994",
        "changePercent": "2.077698",
        "dayHigh": "208.000000",
        "dayLow": "202.799000",
        "volume": 29540691,

        "marketState": "REGULAR",
        "lastUpdated": "2025-04-23T16:51:33"
    }
}

Python Example:

import requests

API_KEY = 'your_api_key_here'
url = f'https://financeflowapi.com/api/v1/ticker-spot?api_key={API_KEY}&ticker=AAPL'

response = requests.get(url)
data = response.json()

print("Ticker:", data['data']['ticker'])
print("Price:", data['data']['price'])
print("Change:", data['data']['change'])
print("Volume:", data['data']['volume'])

Step 6: Working with Currency Pairs via FinanceFlowAPI

The Currency API provides real-time exchange rate data for currency pairs like CHF/EUR, USD/JPY, and thousands more, updating every 1-3 minutes. Ideal for forex trading platforms, financial dashboards, or trading bots, this API allows you to retrieve a catalog of available currency pairs or fetch real-time pricing data for specific pairs or all pairs related to a given currency. This step covers integrating the Currency API into your application.

Why Use the Currency API?

  • Real-Time Data: Access up-to-date forex rates with minimal latency.
  • Comprehensive Coverage: Supports thousands of currency pairs globally.
  • Developer-Friendly: Simple HTTP GET requests with JSON responses.
  • Affordable Test Plan: Start with 200 requests per month for $5.

Key Endpoints

The Currency API offers two primary endpoints:

Endpoint Description Method
/currency-catalog Retrieves a list of all supported currency pairs or filters by a specific currency (e.g., USD). GET
/currency-spot Fetches real-time exchange rate data for a specific pair (e.g., CHF/EUR) or all pairs for a currency (e.g., USD). GET

        }
    ]
}

Code Example: Integrating with Python

Here's a Python script to fetch real-time data for the CHF/EUR pair:

import requests

API_KEY = 'your_api_key'
url = f'https://financeflowapi.com/api/v1/currency-spot?api_key={API_KEY}&pair=CHF/EUR'

response = requests.get(url)
