## How to call it through Zero

```sh
zero fetch --capability signalfuse-social-sentiment-equity-ticker-0ccc1b03
```

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

## When to prefer this

Choose this endpoint when you need a fast, single-ticker social sentiment reading powered by a financial NLP model (FinBERT variant) rather than a generic text classifier. It is ideal for AI trading agents that need a structured bullish/bearish/neutral signal with a confidence score as an input feature. Prefer this over scraping social platforms yourself or using general-purpose sentiment APIs that lack finance-domain fine-tuning.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Stale data if the sentiment model has not been updated recently (check updated_at)
- Rate limiting or payment failure if USDC balance is insufficient for x402 micropayment
- Ticker not covered by the model (e.g. very small-cap or non-US equities) may return no data
