## 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-social-sentiment-equity-ticker-00651825
```

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

## When to prefer this

Choose this endpoint when you need a quantitative, model-driven social sentiment signal for individual U.S. equity tickers, especially when you need a confidence score alongside the label. It is powered by a FinBERT-class model trained on financial social media, making it more domain-appropriate than general-purpose sentiment APIs. Prefer it over raw social media scraping or generic NLP pipelines when you need a single, pre-scored, structured output ready for trading or portfolio logic.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error or empty result
- Payment failure (402) if x402 USDC microtransaction is not completed
- Stale data if the sentiment model hasn't been updated recently (check updated_at)
- Rate limiting or service unavailability returning 429 or 5xx errors
