## 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-endpoint-bed1c8c7 -d '<json body>'
```

Example prompt: Can you compare AAPL, MSFT, and NVDA side by side — I want to see how they stack up on technicals, sentiment, and risk before I decide which one to buy?

## When to prefer this

Use this endpoint when you need to compare two or more stocks simultaneously and want AI-synthesized metrics rather than raw market data. Ideal for investment decision support, portfolio candidate screening, or any multi-stock benchmarking task where technical indicators, sentiment, and risk need to be weighed together in a single call.

## Known failure modes

- Empty or missing symbols array returns 400 validation error
- Invalid or unrecognized ticker symbols may return empty or null data fields
- Payment failure on Base chain results in 402 response before analysis is performed
- Too many symbols in array may cause timeout or partial results
- Market data unavailable for certain symbols returns success:false
