## 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 social-sentiment-c0120bde
```

Example prompt: What's the current bull/bear sentiment for SOL — break it down by source (Farcaster, news, and GDELT) and tell me how it's changed over the last 24 hours and 7 days, plus how confident the signal is.

## When to prefer this

Use this endpoint when you need a multi-source, fused crypto sentiment signal that goes beyond a single social platform — especially when you want to see which source (on-chain social, news sentiment, or global event tone) is driving the signal and how fresh/reliable the underlying data is. Prefer it over single-source sentiment APIs when cross-validation and confidence transparency matter.

## Known failure modes

- Neither sym nor query provided — returns 400 or empty result
- Unknown or very obscure ticker with insufficient data — low confidence score returned
- GDELT or Farcaster data temporarily unavailable — partial breakdown returned with reduced confidence
- Rate limit or payment failure — 402 payment required or 429 response

## How this service works

Composite bull/bear sentiment for a crypto ticker or topic, fused across three ToS-clean sources: Farcaster cast sentiment (open-protocol hub), our crypto-news + Fear&Greed composite, and GDELT world-tone. Returns a normalized score, a per-source breakdown, 24h/7d deltas and a confidence (how much data is under the signal) — so you see which source drives it and how thin the signal is.

## Output

A normalized composite sentiment score (bull/bear), a per-source breakdown showing contributions from Farcaster cast sentiment, crypto-news/Fear&Greed composite, and GDELT world-tone, 24-hour and 7-day deltas showing directional change, and a confidence value indicating data volume behind the signal.
