## 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-for-equity-tickers-e2df73af
```

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

## When to prefer this

Choose this endpoint when you need a fast, NLP-derived social sentiment signal for an individual equity ticker — especially when building trading agents, screening pipelines, or research tools that require a machine-readable bullish/bearish/neutral label with a quantified confidence score. Prefer this over raw social data scrapers when you need a pre-computed, normalized FinBERT score rather than raw text. It is well-suited for agentic workflows that gate trade decisions on sentiment thresholds.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty result
- Stale data if sentiment hasn't been refreshed recently (check updated_at field)
- Payment failure (x402) if USDC balance is insufficient — endpoint returns 402 status
- Rate limiting if calls are made too frequently
- Low confidence scores may indicate ambiguous or thin social signal for less-discussed tickers
