## 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-api-f2821271 -d '<json body>'
```

Example prompt: Screen AAPL, MSFT, NVDA, and TSLA for me — I want to see technical indicators, sentiment scores, and any risk flags so I can decide which ones to hold.

## When to prefer this

Choose this endpoint when you need to screen multiple stock tickers simultaneously for a blend of AI-powered technical analysis, sentiment scoring, and risk metrics in a single call. Prefer it over single-stock quote APIs when you need comparative analysis across a basket of equities, or when you want AI-synthesized signals rather than raw price data.

## Known failure modes

- Missing or empty symbols array returns validation error
- Invalid ticker symbols may return empty or null data per symbol
- Payment failure via x402/Base chain results in 402 response blocking the request
- Rate limiting or service unavailability on Vercel serverless may return 503
- Malformed request body returns 400 bad request
