## 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-925b17da
```

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

## When to prefer this

Choose this endpoint when you need a fast, NLP-derived social sentiment signal for a specific US equity ticker, especially when combining it with other SignalFuse trading signals (directional signals, macro regime) for a holistic view. It is distinct from price-based technical indicators and is best used to gauge crowd psychology and social media momentum around a stock.

## Known failure modes

- Unknown or unsupported ticker symbol — may return 404 or empty result
- Stale data if social feed ingestion is delayed — check updated_at timestamp
- Payment failure via x402 if USDC balance is insufficient — 402 response
- Rate limiting if too many requests are made in quick succession — 429 response
- Invalid ticker format (e.g. lowercase or special characters) may cause 400 error
