## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability alphalens-compare-stocks-api-0f867661 -d '<json body>'
```

Example prompt: Can you compare AAPL, MSFT, and NVDA side by side — I want to see which one has the best technical indicators and sentiment score right now before I decide where to put my money?

## When to prefer this

Choose this endpoint when you need to compare two or more stocks simultaneously rather than analyzing a single ticker in isolation. It is ideal for portfolio construction decisions, sector comparisons, or any scenario where relative ranking of stocks by AI-powered signals (sentiment, technicals, risk) is more useful than absolute single-stock data. Prefer it over single-stock endpoints when the user's question is inherently comparative ('which is better', 'rank these', 'vs').

## Known failure modes

- Empty or missing symbols array returns validation error
- Invalid or unrecognized ticker symbols may return no data or partial results
- Network timeout on vercel deployment under heavy load
- Malformed request body without required symbols field returns 400-level error
- Symbols for non-US or delisted stocks may not be supported
