Installation

# Using pip
pip install fmp-data

# Using poetry
poetry add fmp-data

Quick Start

from fmp_data import FMPDataClient, ClientConfig, LoggingConfig
from fmp_data.exceptions import FMPError, RateLimitError, AuthenticationError

# Method 1: Initialize with direct API key
client = FMPDataClient(api_key="your_api_key_here") # pragma: allowlist secret

# Method 2: Initialize from environment variable (FMP_API_KEY)
client = FMPDataClient.from_env()

# Method 3: Initialize with custom configuration
config = ClientConfig(
    api_key="your_api_key_here", #pragma: allowlist secret
    timeout=30,
    max_retries=3,
    base_url="https://financialmodelingprep.com/api",
    logging=LoggingConfig(level="INFO")
)
client = FMPDataClient(config=config)

# Using with context manager (recommended)
with FMPDataClient(api_key="your_api_key_here") as client: # pragma: allowlist secret
    try:
        # Get company profile
        profile = client.company.get_profile("AAPL")
        print(f"Company: {profile.company_name}")
        print(f"Industry: {profile.industry}")
        print(f"Market Cap: ${profile.mkt_cap:,.2f}")

        # Search companies
        results = client.company.search("Tesla", limit=5)
        for company in results:
            print(f"{company.symbol}: {company.name}")

    except RateLimitError as e:
        print(f"Rate limit exceeded. Wait {e.retry_after} seconds")
    except AuthenticationError:
        print("Invalid API key")
    except FMPError as e:
        print(f"API error: {e}")

# Client is automatically closed after the with block

Key Components

1. Company Information

from fmp_data import FMPDataClient

with FMPDataClient.from_env() as client:
    # Get company profile
    profile = client.company.get_profile("AAPL")

    # Get company executives
    executives = client.company.get_executives("AAPL")

    # Search companies
    results = client.company.search("Tesla", limit=5)

    # Get employee count history
    employees = client.company.get_employee_count("AAPL")

2. Financial Statements

from fmp_data import FMPDataClient

with FMPDataClient.from_env() as client:
    # Get income statements
    income_stmt = client.fundamental.get_income_statement(
        "AAPL",
        period="quarter",  # or "annual"
        limit=4
    )

    # Get balance sheets
    balance_sheet = client.fundamental.get_balance_sheet(
        "AAPL",
        period="annual"
    )

    # Get cash flow statements
    cash_flow = client.fundamental.get_cash_flow_statement("AAPL")

3. Market Data

from fmp_data import FMPDataClient

with FMPDataClient.from_env() as client:
    # Get real-time quote
    quote = client.market.get_quote("TSLA")

    # Get historical prices
    history = client.market.get_historical_price(
        "TSLA",
        from_date="2023-01-01",
        to_date="2023-12-31"
    )

4. Async Support

import asyncio
from fmp_data import FMPDataClient

async def get_multiple_profiles(symbols):
    async with FMPDataClient.from_env() as client:
        tasks = [client.company.get_profile_async(symbol)
                for symbol in symbols]
        return await asyncio.gather(*tasks)

# Run async function
symbols = ["AAPL", "MSFT", "GOOGL"]
profiles = asyncio.run(get_multiple_profiles(symbols))
