epsilab 0.1.1

Python SDK for Epsilab live portfolio data (signals, weights, trades).

Epsilab Python SDK

Minimal Python client and CLI for the Epsilab Website API (pass-through to Strategy-Engine). Auth uses an API key.

Install

pip install epsilab

Install from source

cd /home/matthew/Epsilab/Epsilab-API
python -m venv .venv && source .venv/bin/activate
pip install --upgrade pip
pip install .
# or for development
pip install -e .

Environment

Set these variables or pass explicitly to the client:

• EPSILAB_API_BASE (default https://www.epsilab.ai/api/ext/v1)
• EPSILAB_API_KEY (a user API key created in Account Settings)

Note:

• API access requires an active Pro subscription. Requests from accounts without Pro will be rejected.
• Live endpoints are rate limited (e.g., ~1 request/second sustained with small bursts). Excessive requests will receive HTTP 429.
• Use nextEtaMin from get_live_status() to poll intelligently. For example, if nextEtaMin=80.07, you can sleep ~80 minutes before the next refresh instead of tight-loop polling. The results will be the same.

Python Usage

from epsilab import Epsilab

client = Epsilab(api_base="https://www.epsilab.ai/api/ext/v1", api_key="<epsk_live_...>")

# Note: Running the portfolio via API key is disabled. Use the website to initiate runs.

# Fetch live data (typed models)
latest = client.get_live_latest(return_results_if_fresh=True)          # epsilab.models.LiveLatest
status = client.get_live_status()                                      # epsilab.models.LiveStatus
signals = client.get_portfolio_signals(limit=500)                      # List[epsilab.models.PortfolioSignal]
weights = client.get_portfolio_weights(limit=500)                      # List[epsilab.models.PortfolioWeight]
trades = client.get_live_trades(status="PENDING,EXECUTED", include_positions=True)  # List[epsilab.models.PortfolioTrade]
equity = client.get_live_equity(limit=200)                             # List[epsilab.models.EquityPoint]

print(latest)

CLI Usage

# Set API key in env
export EPSILAB_API_KEY="<epsk_live_...>"

Data models

• get_live_latest() → LiveLatest with fields:

  • run_id: Optional[str]
  • timeframe: Optional[str]
  • signals: List[PortfolioSignal]
  • weights: List[PortfolioWeight]
  • fresh: Optional[bool]
  • recomputed: Optional[bool]

• get_live_status() → LiveStatus with fields:

  • latest_run_id: Optional[str]
  • timeframe: Optional[str]
  • next_eta_minutes: Optional[float]
  • counts: Dict[str, int]

• get_portfolio_signals() → List[PortfolioSignal] with fields:

  • symbol: str, signal_type: str, strength: Optional[float], timestamp: Optional[str], date: Optional[str]

• get_portfolio_weights() → List[PortfolioWeight] with fields:

  • symbol: str, final_weight: Optional[float], raw_weight: Optional[float], timestamp: Optional[str], date: Optional[str]

• get_live_trades() → List[PortfolioTrade] with fields:

  • id: str, symbol: str, side: str, qty: Optional[float], planned_price: Optional[float], planned_at: Optional[str], status: str, reasoning: Optional[str]

• get_live_members() → List[PortfolioMember] with fields:

  • strategy_id: str, effective_weight: Optional[float], name: Optional[str], visibility: Optional[str]

• get_live_equity() → List[EquityPoint] with fields:

  • date: str, value: float

All models expose to_dict(), to_json(), and log() helpers for convenient logging.
