## 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-620ebb4d -d '<json body>'
```

Example prompt: Compare NVDA, AMD, and INTC side by side — I want to see their technical indicators, sentiment scores, and risk profiles to figure out which one looks strongest right now.

## When to prefer this

Choose this endpoint when you need to evaluate multiple stocks simultaneously against each other rather than analyzing a single stock in isolation. It is ideal for portfolio construction, sector comparisons, or investment decision support where relative ranking and cross-stock sentiment and technical signal comparison matters. Prefer this over single-stock endpoints when the user explicitly wants to pit two or more tickers against each other.

## Known failure modes

- Empty or missing symbols array returns validation error
- Invalid ticker symbols may return empty data or partial results
- More than a supported number of symbols may cause truncation or error
- Network timeout if upstream data providers are slow
- Payment failure via x402 on Base chain if insufficient USDC balance
