## 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 vidar-agent-sentiment-based-trade-signal-dry-run-a229cde4 -d '<json body>'
```

Example prompt: Based on the current sentiment around $SOL — there's been a lot of bullish chatter on crypto Twitter about a major breakout — run a dry-run trade signal for me and tell me if I should be buying, selling, or holding.

## When to prefer this

Choose this endpoint when you need a structured trade signal derived from sentiment analysis in a safe, no-execution (dry-run) context — ideal for backtesting sentiment strategies, paper trading, or deciding a position direction without committing real capital. Prefer over the raw sentiment endpoint when you specifically need a trading recommendation rather than just a sentiment score.
