Hermes

Universal data acquisition and feature engineering SDK for intelligence, finance, and defense applications.

Hermes fetches data from 40+ free global sources, normalizes it, engineers intelligence-ready features, and exposes everything through a clean Python interface (with CLI and TUI). It is not an API server — it is an SDK you import, run, and own.

pip install hermes-plt
# or
uv add hermes-plt

Quickstart

from hermes import Hermes

hr = Hermes()

# FRED — US macro data (free key required)
hr.fred.connect("YOUR_API_KEY")
gdp = hr.fred.get_series("GDP")

# FRED — search by keyword
results = hr.fred.search_series("inflation")

# FRED — multiple series in one DataFrame
multi = hr.fred.get_multiple_series(["GDP", "UNRATE", "CPIAUCSL"])

# World Bank — no key needed
china_gdp = hr.world_bank.get_data("NY.GDP.MKTP.CD", country="CHN")

# World Bank — browse indicators
hr.world_bank.search_indicators("gdp")

# Feature engineering
from hermes.features import FeatureEngineer
fe = FeatureEngineer()
risk = fe.build_country_risk_features(country="UKR", date="2026-07-14")

Every connector returns a pandas DataFrame. Optional export=True saves to JSON, CSV, Parquet, or Pickle.
