## 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-stock-compare-api-e40c8d3d -d '<json body>'
```

Example prompt: Can you compare AAPL, MSFT, and NVDA side by side — I want to see their technical indicators, sentiment scores, and risk profiles so I can decide which one to buy?

## When to prefer this

Choose this endpoint when you need a direct multi-stock comparison rather than analyzing a single stock in isolation. It is ideal for investment decision-making scenarios where a user has narrowed down to 2-5 candidates and wants a structured head-to-head view of technicals, sentiment, and risk. Prefer this over single-stock analysis endpoints when the core question is 'which one is better' rather than 'tell me about this one.'

## Known failure modes

- Invalid or unrecognized ticker symbols return an error or empty data
- Too many symbols in the array may hit rate or processing limits
- Symbols for non-US or OTC equities may return incomplete data
- Network timeout on the Vercel serverless function during market hours under load
- Payment failure on Base chain (insufficient USDC) blocks the request
