hn = HackerNewsSource()
top = hn.get_top_stories(limit=10)
for story in top:
    print(f"[{story.score:4d}] {story.title[:70]}")

RSS / Atom Feed Parsing

ts = TrendScout()

# Preset categories: tech | ai | business | python | startup
tech_news = ts.get_rss_trends(category="tech", limit=15)
ai_news   = ts.get_rss_trends(category="ai", limit=10)

    ],
    limit=20,
)

Trend Velocity Scoring

velocity = ts.get_trend_velocity("quantum computing")
print(velocity)
# Trend   : quantum computing
# Velocity: [████████░░░░░░░░░░░░] 0.42
# Status  : PEAK
# Articles: 12  |  Avg engagement: 156
# → Trending now — maximise exposure before it plateaus

# Status meanings:
# emerging  (0.70–1.00) — fast-growing, act now
# peak      (0.40–0.70) — trending, maximise reach
# stable    (0.15–0.40) — evergreen, good for long-form
# declining (0.00–0.15) — losing momentum, pivot keywords

Multi-Topic Comparison

report = ts.analyze_topics(
    ["AI agents", "blockchain", "quantum computing", "WebAssembly", "Rust"],
    source="hackernews",
)
print(report.to_string(index=False))
