## When to prefer this

Choose this endpoint when you need to evaluate multiple stock tickers simultaneously with a combined view of technical indicators and AI sentiment scoring — particularly useful for watchlist scans, pre-trade research, or portfolio rebalancing workflows where you want a fast multi-stock snapshot rather than deep single-stock analysis.

## Known failure modes

- Empty or missing symbols array returns validation error
- Invalid or unrecognized ticker symbols may return null or missing data for those entries
- Network or payment failure on Base chain causes request to not process
- Rate limiting or quota exhaustion returns an error response
- Service unavailability on Vercel hosting returns 5xx errors
