## 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

Example prompt: What topics or assets are trending with the strongest sentiment signals right now — show me what the crowd is feeling most bullish or bearish about across DeFi and governance.

## When to prefer this

Choose this endpoint when you need a real-time snapshot of what topics or assets are emotionally resonating most strongly with the crowd, particularly in crypto, DeFi, or governance contexts. It is preferable over single-asset sentiment endpoints when you want a ranked trending view rather than sentiment for a specific known asset.

## Known failure modes

- No trending data available for the requested time window — returns empty list
- Invalid input parameters cause a 400 error
- Service unavailable or Vercel cold-start timeout returns 500
- Payment not received or x402 payment header missing/invalid causing 402 rejection
- Rate limiting if too many calls are made in quick succession

## How this service works
