✨ Feature Highlights

Capability	Details
yfinance-style download()	Mirrors yfinance.download semantics including period, interval, metrics, threads, group_by, and progress hooks.
Multi-metric alias registry	Built-in alias table for price, OHLC, marketcap, and other endpoints, plus support for custom endpoint dictionaries.
Request resilience	Injects API keys automatically, supports proxy-aware requests.Session, and retries with exponential backoff on 429/50x responses.
Pandas-native output	DateTime index + MultiIndex columns flow directly into NumPy, pandas, polars, or backtesting engines.
Visualization ready	Bundled Plotly script launches a TradingView-style ETH/SOL dashboard with one command.

📦 Installation

pip install glassnode-python           # coming soon on PyPI
pip install -e .[test]                 # developer setup
pip install -e .[viz]                  # Plotly dashboard extras

Until the project is on PyPI you can install straight from the repository root:

pip install .

⚡ Quickstart (30 seconds)

from glassnode_python import download
from dotenv import load_dotenv
import os

load_dotenv()
api_key = os.environ["GLASSNODE_API_KEY"]

btc = download("BTC", period="3mo", metrics=["price"], api_key=api_key)
print(btc.tail())

The helper returns a pandas dataframe with a DateTime index and a column MultiIndex of (Attribute, Ticker) by default.

🧰 Essential Recipes

Multi-asset OHLC (yfinance style)

rich = download(
	["BTC", "ETH", "SOL"],
	period="1y",
	interval="24h",
	metrics=["ohlc"],
	group_by="ticker",   # switch to (Ticker, Attribute)
	threads=True,
	api_key=api_key,
)

Mix & match metrics

matrix = download(
	"BTC",
	metrics=["price", "marketcap", "mvrv"],
	period="6mo",
	rounding=2,
	dropna=True,
	api_key=api_key,
)

Custom endpoint mapping

download(
	"ETH",
	metrics={
		"sopr": {"endpoint": "/v1/metrics/market/sopr"},
		"ohlc": {"endpoint": "/v1/metrics/market/price_usd_ohlc", "multi": True},
		"fees": {
			"endpoint": "/v1/metrics/transactions/transfers_volume_sum",
			"column": "TransferVolume",
		},
	},
	api_key=api_key,
)

Full-control client

from glassnode_python import GlassnodeClient
import requests

session = requests.Session()
session.headers.update({"User-Agent": "glassnode-python/0.2"})

client = GlassnodeClient(
	api_key=api_key,
	session=session,
	proxies={"https": "http://127.0.0.1:7890"},
	max_retries=5,
	retry_backoff=1.5,
)

df = client.download(
	["BTC", "SOL"],
	start="2025-01-01",
	end="2025-12-31",
	metrics=["price", "volume"],
	progress=False,
)

📊 Metric Alias Catalog

Alias	Endpoint	Columns
ohlc	/v1/metrics/market/price_usd_ohlc	Open, High, Low, Close
price	/v1/metrics/market/price_usd_close	Price
marketcap	/v1/metrics/market/marketcap_usd	Marketcap
volume	/v1/metrics/market/spot_volume_daily_sum	Volume
mvrv	/v1/metrics/market/mvrv	Mvrv
realizedcap	/v1/metrics/market/realizedcap_usd	RealizedCap

Aliases respect group_by, rounding, and fill methods so the dataframe layout stays predictable.

📺 TradingView-like Dashboard

pip install -e .[viz]
python scripts/eth_sol_tradingview.py

• Fetches one year of daily OHLC candles for ETH and SOL (sequential mode to stay within rate limits).
• Adds EMA20/EMA50 overlays plus Plotly dark theme, linked hover, and full zoom/pan controls.
• Customize via the EMA_WINDOWS constant or export HTML with fig.write_html().

---

🔐 API Keys & Environment

echo "GLASSNODE_API_KEY=your-secret" >> .env

• If api_key is omitted, the module lazily loads .env on first use.
• Pass api_key= for one-off calls or client= to reuse a configured GlassnodeClient.

🧪 Testing & Release Flow

pip install -e .[test]
pytest

python -m build
twine upload dist/*

Update __version__ inside src/glassnode_python/__init__.py and the project.version in pyproject.toml before cutting a release.
