## 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 coin-railz-stock-sentiment-analysis-71bdc668 -d '<json body>'

## When to prefer this

Use this endpoint when you need a holistic, AI-synthesized view of stock market sentiment that combines news, technicals, and institutional signals in a single call — especially useful for AI agents making pre-trade assessments or portfolio monitoring tasks. Prefer over raw news APIs or technical indicator endpoints when you want a unified sentiment score rather than raw data.

## Known failure modes

- Payment not processed correctly leads to 402 response blocking access
- Stale or unavailable news data may reduce sentiment accuracy
