## 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 sentiment-analysis-api-web-news-blogs-42cf2367 -d '<json body>'
```

Example prompt: What's the current sentiment around Bitcoin across news and blogs — give me the polarity breakdown and the overall sentiment score?

## When to prefer this

Choose this endpoint when you need multi-source aggregated sentiment (news + blogs + web) with both polarity counts AND emotional connotations in a single call. Ideal for crypto/market sentiment, brand monitoring, and opinion-mining agents that need a composite [-1,1] score rather than raw article text. Prefer over raw news search when you need quantified sentiment rather than article content.

## Known failure modes

- Empty or overly broad query returns noisy or null sentiment data
- Query with no web coverage returns null score fields
- Invalid pageTypes enum value causes request rejection
- Query exceeds 300 character limit returns validation error
- Upstream data source unavailable may return null upstream cost and degraded results

## Output

Returns a sentiment score between -1 and 1, polarity counts (positive, negative, neutral citations), and emotional connotation scores (anger, happiness, love, sadness, fun, share) aggregated from web, news, blogs, message boards, and/or ecommerce sources matching the query.
