financial-news-scraper 0.1.0

Multi-source financial news library with quality scoring and ticker extraction

finews

The financial news data library for Python.

pip install financial-news-scraper

---

Fetch, extract, and score financial news articles from 13 sources in one call. Returns clean Article objects with full text, extracted tickers, and a quality score — no database required.

What gap does this fill? Existing options are either single-source (newsapi-python, feedparser), return no article body (yfinance), or have no quality layer at all. finews covers multiple sources, runs full-text extraction via trafilatura, deduplicates across sources, and scores every article on a 0–1 quality scale.

---

Install

pip install financial-news-scraper

Python 3.9+ required. For PostgreSQL persistence add the optional extra:

pip install "financial-news-scraper[postgres]"

---

Quickstart

from finews import Scraper

scraper = Scraper(sources=["yahoofinance", "cnbc"])
articles = scraper.fetch(days_back=1)

for a in articles:
    print(a.title, a.tickers, a.quality_score)

---

Examples

Filter by ticker

scraper = Scraper(sources=["yahoofinance", "benzinga", "cnbc"])
articles = scraper.fetch(tickers=["AAPL", "MSFT"], days_back=7)

for a in articles:
    print(f"[{', '.join(a.tickers)}] {a.title}")
    print(f"  source={a.source_name}  quality={a.quality_score:.2f}  words={a.word_count}")

Use API sources

scraper = Scraper(
    sources=["newsapi", "finnhub"],
    newsapi_key="YOUR_KEY",
    finnhub_api_key="YOUR_KEY",
)
articles = scraper.fetch(tickers=["NVDA"], days_back=3, min_quality=0.8)

API keys can also be set via environment variables — see Configuration.

Persist to a database

# SQLite
articles = scraper.fetch(save_to="sqlite:///./financial_news.db")

# PostgreSQL
articles = scraper.fetch(save_to="postgresql://user:pw@localhost/mydb")

Tables are created automatically if they don't exist. fetch() always returns the Article list regardless.

Custom source

Subclass BaseFetcher to add any source the pipeline doesn't cover.

from finews import Scraper, BaseFetcher, SourceConfig
from scraper.models.article import RawArticle
from datetime import datetime, timezone

class MySource(BaseFetcher):
    def __init__(self, api_key: str):
        super().__init__(SourceConfig(name="my_source", type="api", rate_limit_rps=2.0))
        self._api_key = api_key

    def fetch(self, from_dt=None, to_dt=None, ticker=None, **kwargs) -> list[RawArticle]:
        resp = self._get(
            "https://api.example.com/news",
            params={"key": self._api_key, "symbol": ticker},
        )
        return [
            RawArticle(
                url=item["url"],
                title=item["title"],
                published_at=datetime.fromisoformat(item["published_at"]),
                source_name=self.config.name,
                summary=item.get("summary"),
            )
            for item in resp.json()["articles"]
        ]

# Mix custom and built-in sources freely
scraper = Scraper(sources=[MySource(api_key="secret"), "cnbc", "yahoofinance"])
articles = scraper.fetch(tickers=["AAPL"])

BaseFetcher provides _get() and _post() with automatic rate limiting and exponential-backoff retries. The rest of the pipeline (extraction, dedup, quality scoring, ticker extraction) runs automatically.

Configuration

Set these in a .env file or as environment variables. Only the API keys for sources you actually use are required.

# Required for Scraper(sources=["newsapi"])
NEWSAPI_KEY=

# Required for Scraper(sources=["finnhub"])
FINNHUB_API_KEY=

# Optional — defaults shown
DATABASE_URL=sqlite:///./financial_news.db
MIN_WORD_COUNT=150
LANGUAGE_CONFIDENCE_THRESHOLD=0.95
REQUEST_TIMEOUT_SECONDS=30
MAX_RETRIES=3
LOG_LEVEL=INFO

Copy .env.example to get started:

cp .env.example .env

CLI

A command-line interface ships alongside the Python API for ops tasks:

# One-time setup
scraper db init

# Run sources
scraper scrape --all
scraper scrape --source cnbc_rss

# Historical backfill (GDELT and Wayback Machine)
scraper backfill --source gdelt --start 2020-01-01 --end 2025-01-01 --workers 4

# Query stored articles
scraper query --ticker AAPL --min-quality 0.8 --format csv

# Real-time daemon
scraper scheduler start --daemon
