yukka 0.2.5

Wrapper around Yukka APIs for getting easy access to quantitative insights

yukka

A Python client for YUKKA Lab's sentiment and financial data APIs. Pull news sentiment, entity resolution, and market data directly into your Python environment.

from yukka import Session, Asset
from yukka.data import stoxx600

with Session() as session:  # reads YUKKA_TOKEN from environment
    bmw = Asset.from_isin("DE0005190003", session.resolver)
    df = session.sentiment(bmw, date_from="2026-01-01")

Installation

pip install yukka

Requires Python 3.13+.

Authentication

Contact YUKKA Lab to request API token access.

Set the token as an environment variable:

export YUKKA_TOKEN="eyJ..."

Or pass it explicitly:

from yukka import Session

session = Session(token="eyJ...")

Quick Start

Using a pre-validated universe

The package ships with pre-resolved constituent lists for major indices. No entity resolution needed.

from yukka import Session, Asset
from yukka.data import stoxx600, sp500, ftse100, nasdaq100

# Load STOXX 600 constituents (isin, ric, name, yukka_id, ...)
universe = stoxx600()

# Create assets from YUKKA IDs and fetch sentiment
assets = Asset.from_yukka_id(universe["yukka_id"].to_list())

with Session() as session:
    df = session.sentiment(assets, date_from="2026-01-01", date_to="2026-02-01")

Creating assets from different identifier types

from yukka import Session, Asset

with Session() as session:
    # From YUKKA ID (no API call needed)
    bmw = Asset.from_yukka_id("company:bmw")

    # From ISIN (resolves via Metadata API)
    siemens = Asset.from_isin("DE0007236101", session.resolver)

    # From RIC code (resolves via bundled master file)
    sap = Asset.from_ric("SAPG.DE")

    df = session.sentiment([bmw, siemens, sap], date_from="2026-01-01")

Batch requests

Large entity lists are automatically batched (default 50 per request):

with Session() as session:
    assets = Asset.from_ric(universe["constituent_ric"].to_list())
    df = session.sentiment(assets, date_from="2025-01-01", batch_size=50)

Sentiment

Fetch daily sentiment counts (positive / neutral / negative) for one or more assets:

from yukka import Session, Asset

with Session() as session:
    bmw = Asset.from_yukka_id("company:bmw")
    siemens = Asset.from_isin("DE0007236101", session.resolver)

    df = session.sentiment([bmw, siemens], date_from="2026-01-01", date_to="2026-02-01")

Returns a Polars DataFrame with columns: date, entity, positive, neutral, negative.

Events

Fetch event data for assets. The raw response uses numeric event IDs — call .map() to translate them to human-readable names.

from yukka import Session, Asset

with Session() as session:
    bmw = Asset.from_yukka_id("company:bmw")
    siemens = Asset.from_isin("DE0007236101", session.resolver)

    # Raw events — numeric event IDs, factuality codes, and time codes
    events = session.events([bmw, siemens], date_from="2026-01-01", date_to="2026-02-01")

    # Mapped events — human-readable event names, roles, factuality, and temporality
    mapped = events.map()

The .map() method translates numeric codes to human-readable labels:

factuality codes

0	fact
1	counterfact
2	possible
3	counterpossible
4	probable
5	counterprobable

API Reference

Session

High-level entry point. Reads YUKKA_TOKEN from the environment automatically.

Method	Description
session.sentiment(assets, date_from, date_to)	Fetch daily sentiment counts (positive / neutral / negative)
session.events(assets, date_from, date_to)	Fetch events; returns EventsFrame — call .map() for human-readable labels
session.event_names()	Dict of event ID → name (e.g. {"E6_B": "Acquisition"})
session.resolver	EntityResolver for ISIN → YUKKA ID lookups
session.today	Today's date

Asset

Immutable representation of a YUKKA entity.

Factory	Description
Asset.from_yukka_id(id)	From a YUKKA compound key, e.g. "company:bmw"
Asset.from_isin(isin, resolver)	From an ISIN via Metadata API lookup
Asset.from_ric(ric)	From a RIC code via bundled master file

All factory methods accept a single value or a list.

YukkaClient

Low-level client for direct API access, if you need more control than Session provides.

from yukka import YukkaClient

with YukkaClient.from_token("eyJ...") as client:
    df = client.sentiment(["company:bmw", "company:siemens"], "2026-01-01", "2026-01-31")

Pre-validated universes

from yukka.data import stoxx600, sp500, ftse100, nasdaq100

df = stoxx600()   # STOXX Europe 600
df = sp500()      # S&P 500
df = ftse100()    # FTSE 100
df = nasdaq100()  # NASDAQ 100

Each returns a Polars DataFrame with isin, constituent_ric, constituent_name, and yukka_id columns.
