Installation

pip install alpha-vantage-client

Quick Start

from alpha_vantage_client import AlphaVantageClient

# Initialize with your API key
client = AlphaVantageClient(
    api_key="YOUR_API_KEY",
    default_symbol="AAPL",
    default_datatype="json"
)

# Get stock data
data = client.query("time_series_daily", symbol="AAPL")

# Get technical indicators
sma_data = client.query("sma", symbol="AAPL", interval="daily", series_type="close", time_period=20)

# Get economic data
gdp_data = client.query("real_gdp", interval="quarterly")

# Get news sentiment
news_data = client.query("news_sentiment", tickers="AAPL,TSLA", topics="technology")

Advanced Usage

Setting Defaults

client = AlphaVantageClient(
    api_key="YOUR_API_KEY",
    default_symbol="AAPL",
    default_datatype="json",
    default_interval="daily",
    default_series_type="close",
    default_time_period=20
)

# Now you can call methods without specifying common parameters
sma_data = client.query("sma")  # Uses defaults
rsi_data = client.query("rsi")  # Uses defaults

Discovering Endpoints

# Get all available endpoints
all_endpoints = client.get_available_endpoints()

# Get endpoints by category
economic_endpoints = client.get_available_endpoints(category="economic")
tech_indicators = client.get_available_endpoints(category="technical_indicators")

# Search for specific endpoints
gdp_endpoints = client.get_available_endpoints(filter_by="gdp")

# Get detailed information
detailed_info = client.get_available_endpoints(detailed=True, category="economic")

Advanced Analytics

# Fixed window analytics
analytics = client.query("analytics_fixed_window",
                        SYMBOLS="AAPL,MSFT,IBM",
                        RANGE="2023-07-01",
                        INTERVAL="DAILY",
                        CALCULATIONS="MEAN,STDDEV,CORRELATION")

# Sliding window analytics
sliding_analytics = client.query("analytics_sliding_window",
                                SYMBOLS="AAPL,IBM",
                                RANGE="2month",
                                INTERVAL="DAILY",
                                WINDOW_SIZE=20,
                                CALCULATIONS="MEAN,STDDEV(annualized=True)")

Configuration

The client supports extensive configuration options:

client = AlphaVantageClient(
    api_key="YOUR_API_KEY",
    # Time series defaults
    default_symbol="AAPL",
    default_interval="daily",
    default_outputsize="compact",
    default_datatype="json",
    
    # Technical indicator defaults
    default_series_type="close",
    default_time_period=20,
    
    # Other defaults
    default_adjusted=True,
    default_extended_hours=False
)

Error Handling

The client provides clear error messages and validation:

try:
    data = client.query("sma", symbol="INVALID", interval="invalid")
except ValueError as e:
    print(f"Validation error: {e}")
except RuntimeError as e:
