## 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 ghost77-sentiment-alpha-a0b8632c -d '<json body>'
```

Example prompt: What's the current sentiment and any directional alpha on $ARB right now? Include X/Twitter results in the analysis.

## When to prefer this

Choose this endpoint when you need a synthesized directional signal — not just raw social data — combining sentiment assessment with identified catalysts and source attribution for a specific crypto asset or topic. Prefer over generic sentiment APIs when you want crypto-native alpha framing and optional X/Twitter inclusion, paid per-call with no account setup required.

## Known failure modes

- Empty or too-short query string (minLength:1 violation) returns validation error
- Unknown token symbol or niche project with insufficient social data may return thin or low-confidence results
- X/Twitter search may be rate-limited or unavailable, reducing source coverage
- $2.20 USDC payment on Base must succeed via x402 protocol before data is returned; failed payment returns 402
- Truncated or ambiguous query (e.g. single letter) may return irrelevant sentiment
