## 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 agentrxi-cited-web-answer-4c33e096
```

Example prompt: What are the main causes of the 2024 global semiconductor shortage? Search the web and give me a cited answer reading 5 sources.

## When to prefer this

Choose this endpoint when you need a grounded, verifiable answer with traceable citations from live web pages — not just a language model's internal knowledge. Ideal for current events, factual lookups, and any situation where the user needs to verify sources. Prefer over a plain web search when you want a synthesized, readable answer rather than a list of links. Prefer over a raw LLM completion when recency, accuracy, and citations matter.

## Known failure modes

- Question parameter 'q' missing — returns 400 error
- Web pages for topic are unavailable or blocked — answer may be incomplete or fallback response returned
- Sources parameter outside 2-6 range may be rejected or clamped
- Payment failure (x402) if USDC balance insufficient — returns 402
- Very recent events may not yet be indexed or readable by crawler
- Ambiguous or very broad questions may yield low-quality synthesized answers

## How this service works

Cited answers: ask a question, get a concise answer written from live web pages with numbered [n] citations and the source list. Searches the web, reads the top pages and writes only from what they say (gpt-oss-120b).

## Output

A concise natural-language answer to the question, with numbered [n] inline citations linking each claim to its source, followed by a numbered list of source URLs from the live web pages that were read.
