## 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-screener-6235c403 -d '<json body>'
```

Example prompt: Can you screen AAPL, MSFT, NVDA, and TSLA through AlphaLens and tell me which ones are looking strongest right now based on AI signals?

## When to prefer this

Use this endpoint when you need to screen or rank multiple stock tickers simultaneously using AI-powered signals, and want to pay per request without a subscription. Best when comparing a watchlist or basket of equities for relative strength or opportunity.

## Known failure modes

- Missing required symbols array returns validation error
- Empty symbols array may return empty data
- Invalid ticker symbols may return no data or error for those symbols
- Payment failure on Base chain results in 402 response
