## 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 signalfuse-real-time-social-sentiment-analysis-21dc124d
```

Example prompt: What's the current social sentiment for BTC right now — is it bullish or bearish, and how confident is the signal?

## When to prefer this

Use this endpoint when an AI trading agent needs a quick, real-time read on social market sentiment for a specific crypto asset to inform directional bias or risk decisions. Prefer this over generic news APIs when you need a structured, scored sentiment signal (label + confidence) suitable for programmatic trading logic rather than raw text.

## Known failure modes

- Unknown or unsupported symbol returns 404 or empty result
- Stale data if social feeds are delayed or unavailable
- Payment failure via x402 if USDC balance is insufficient on Base
- Rate limiting if too many calls are made in rapid succession
- Symbol format mismatch (e.g. 'bitcoin' vs 'BTC') may return no result
