## 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 coin-railz-token-sentiment-analysis-45ee5030 -d '<json body>'
```

Example prompt: What's the current social sentiment and momentum for PEPE on Ethereum right now — is it bullish, bearish, or neutral and what's the sentiment score?

## When to prefer this

Use this endpoint when an agent needs real-time social sentiment signals for a specific crypto token, especially for trading decisions, market mood checks, or when incorporating sentiment momentum into portfolio or trading strategies. Prefer this over general news APIs when you need a quantified -100 to 100 score and directional momentum classification specific to crypto tokens.

## Known failure modes

- Unknown or unsupported token symbol returns error or null data
- Unsupported chain value may fall back to Ethereum default or return an error
- Low social activity tokens may return neutral score with limited signal confidence
- Missing required tokenSymbol field returns validation error
- Service unavailable or rate limited returns HTTP 402 or 5xx error
