Financial Modeling Prep (FMP) API Integration

Comprehensive financial data API specializing in fundamental analysis, SEC filings, institutional holdings (13F), congressional trading data, and pre-computed valuations.

Quick Start

Authentication

# Environment variable (recommended)
export FMP_API_KEY="your_api_key"

# Or in .env file
FMP_API_KEY=your_api_key

Basic Usage (Python)

import requests
import os

API_KEY = os.getenv("FMP_API_KEY")
BASE_URL = "https://financialmodelingprep.com/stable"

def get_quote(symbol: str) -> dict:
    """Get real-time quote for a symbol."""
    response = requests.get(
        f"{BASE_URL}/quote",
        params={"symbol": symbol, "apikey": API_KEY}
    )
    data = response.json()
    return data[0] if data else {}

# Example
quote = get_quote("AAPL")
print(f"AAPL: ${quote['price']:.2f} ({quote['changePercentage']:+.2f}%)")

Important: New Endpoint Format

FMP migrated to /stable/ endpoints. Legacy /api/v3/ endpoints require existing subscriptions.

# NEW format (use this)
BASE_URL = "https://financialmodelingprep.com/stable"

# OLD format (legacy only)
# BASE_URL = "https://financialmodelingprep.com/api/v3"
