edge-sdk 0.1.0

Python SDK for accessing Edge's agricultural commodity data including CME timeseries, USDA, CFTC, and market data

Edge SDK

Python SDK for accessing Edge's agricultural commodity data API. Get real-time and historical CME futures data, USDA market reports, and more.

Installation

pip install edge-sdk

Quick Start

from edge import Edge

# Initialize the client with your API key
edge = Edge(api_key="your-api-key")

# Get CME futures data
corn_data = edge.cme.get_futures_prices(
    symbol="ZCH5",
    start_date="2025-01-01",
    end_date="2025-01-31"
)

print(corn_data.head())

Authentication

API Key Required: All API endpoints require a valid API key. Get your API key from the Edge platform.

Configuration Options

Option 1: Pass API key directly

from edge import Edge

edge = Edge(api_key="edge_your_api_key_here")

Option 2: Use environment variables

export EDGE_API_KEY="edge_your_api_key_here"
export EDGE_API_BASE_URL="https://edge-api-730192956959.us-east4.run.app"  # optional

from edge import Edge

edge = Edge()  # Automatically uses EDGE_API_KEY from environment

Option 3: Use .env file

# .env file
EDGE_API_KEY=edge_your_api_key_here
EDGE_API_BASE_URL=https://edge-api-730192956959.us-east4.run.app

from edge import Edge

edge = Edge()  # Automatically loads from .env

Usage Examples

Complete Workflow Example

from edge import Edge
import pandas as pd

# Initialize client
edge = Edge(api_key="your-api-key")

# 1. Discover available symbols
symbols = edge.cme.list_symbols()
print(f"Found {len(symbols)} CME symbols")

# 2. Get futures data for corn
corn = edge.cme.get_futures_prices(
    symbol="ZCZ5",
    start_date="2025-01-01",
    end_date="2025-01-31"
)

# 3. Calculate statistics
print(f"Average Close: ${corn['close'].mean():.2f}")
print(f"High: ${corn['high'].max():.2f}")
print(f"Low: ${corn['low'].min():.2f}")

# 4. Get spread data
spread = edge.cme.get_spread_data(
    spread_symbol="ZCZ5-ZCH6",
    start_date="2025-01-01"
)

print(f"Current Spread: ${spread.iloc[-1]['close']:.2f}")

# Close the client
edge.close()

Working with DataFrames

All data is returned as pandas DataFrames for easy analysis:

import matplotlib.pyplot as plt

# Get CME data
data = edge.cme.get_futures_prices("ZCH5", start_date="2025-01-01")

# Plot OHLC
data.plot(x="observation_datetime", y=["open", "high", "low", "close"], figsize=(12, 6))
plt.title("Corn Futures - March 2025")
plt.show()

# Calculate statistics
print(data[["open", "high", "low", "close"]].describe())

# Resample to weekly
weekly = data.set_index("observation_datetime")["close"].resample("W").mean()

Error Handling

from edge import Edge
from edge.exceptions import EdgeAPIError, DataNotFoundError, AuthenticationError

try:
    edge = Edge(api_key="your-api-key")
    data = edge.cme.get_futures_prices("INVALID_SYMBOL")
except AuthenticationError as e:
    print(f"Authentication failed: {e}")
except DataNotFoundError as e:
    print(f"Data not found: {e}")
except EdgeAPIError as e:
    print(f"API error: {e}")

Context Manager

Use the client as a context manager for automatic cleanup:

with Edge(api_key="your-key") as edge:
    data = edge.cme.get_futures_prices("ZCH5")
    print(data.head())
    # Client automatically closes when done

Advanced Configuration

# Custom base URL and timeout
edge = Edge(
    api_key="your-api-key",
    base_url="http://localhost:8000",  # for local development
    timeout=60  # 60 second timeout
)

# Get limited results for performance
data = edge.cme.get_futures_prices(
    symbol="ZCH5",
    limit=100  # Only get 100 most recent records
)
