---
## Web Add-ons (Optional)
### A) News search (DuckDuckGo via `ddgs`)
This skill vendors a helper script (`scripts/ddg_search.py`).
Dependency:
```bash
pip3 install -U ddgs
```
Run:
```bash
python3 scripts/news.py NVDA --max 8
# or
python3 scripts/ddg_search.py "NVDA earnings guidance" --kind news --max 8 --out md
```
### B) Options / Flow (browser-first)
Unusual Whales frequently blocks scraping/headless access.
So the recommended approach is: **open the pages in a browser and summarize what you can see**.
Quick link helper:
```bash
python3 scripts/options_links.py NVDA
```
Common URLs:
- `https://unusualwhales.com/stock/{TICKER}/overview`
- `https://unusualwhales.com/live-options-flow?ticker_symbol={TICKER}`
- `https://unusualwhales.com/stock/{TICKER}/options-flow-history`

`yf.py` supports:
- `price`
- `fundamentals`
- `history`
- `pro`
- `chart` (alias)
- `report`
- `option` (best-effort; browser fallback recommended)
Check:
```bash
python3 scripts/yf.py --help
```
