## 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 content-hugen-tokyo-a838891b
```

Example prompt: Can you fully analyze this article for me — https://example.com/article — I want to know its sentiment score, what type of content it is (news, blog, tutorial, etc.), the main topics, any named entities like people or organizations, and how credible it seems?

## When to prefer this

Choose this endpoint when you need a multi-dimensional content analysis in a single call — specifically when you need sentiment, topic, entities, content type, and credibility all at once without setting up your own LLM pipeline or prompt engineering. Ideal for content moderation pipelines, news feed analysis, research aggregation, or any workflow that needs to quickly classify and evaluate web content at scale. Prefer this over general-purpose LLM calls when you want structured, consistently formatted output at low cost ($0.02/call).

## Known failure modes

- URL is inaccessible or returns non-200 status — analysis cannot be performed
- URL points to non-text content (e.g. PDF, image) — extraction may fail or return empty results
- Page content is too short or lacks meaningful text — low-confidence or empty analysis returned
- Payment not included or invalid — 402 Payment Required response
- Rate limit exceeded — too many requests in a short period

## How this service works

Comprehensive AI content analysis — sentiment scoring (-1.0 to 1.0), topic classification, named entity extraction, content type detection (news/blog/docs/tutorial), and credibility assessment. Returns structured analysis ready for immediate use. No LLM integration needed. Accepts USDC payments on Base and Solana

## Output

Returns a structured analysis object including: a sentiment score between -1.0 (most negative) and 1.0 (most positive), topic classification labels, named entities (people, organizations, locations, products, events), content type detection (news, blog, documentation, tutorial), and a credibility assessment score — all ready for immediate downstream use without additional LLM processing.
