## How to call it through Zero

```sh
zero fetch --capability powahub-daily-stock-screen-6247770e
```

Example prompt: What are today's top five AI-screened S&P 500 large-cap stock picks, and can you show me the thesis, biggest risk, and confidence level for each one?

## When to prefer this

Choose this endpoint when you need a concise, pre-ranked daily shortlist of US large-cap stock ideas with written rationale and risk notes, rather than building your own screen from raw price or fundamentals data. It is ideal for daily briefing agents, newsletter automation, or watchlist seeding where qualitative thesis and confidence context matter alongside the ticker symbol.

## Known failure modes

- No picks available yet if called before the daily refresh completes post-US close
- Weekend or market holiday — screen may not update on non-trading days
- Rate limit or payment failure (x402 micropayment not processed) returns a payment-required error
- Upstream AI research pipeline failure resulting in empty or partial results

## How this service works

Five US large-cap stocks ranked by a daily AI research screen. Each name carries a written thesis, the most material risk, a confidence level and cited sources. Covers the S&P 500, refreshed each weekday after the US close. Ranked screen output, not financial advice.

## Output

A ranked list of five S&P 500 large-cap stock picks for today, each containing the stock ticker/name, a written investment thesis, the most material risk factor, a confidence level, and cited research sources. Data is refreshed each weekday after the US market close.
