## 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 agent402-tools-article-digest-9de00a89 -d '<json body>'
```

Example prompt: Give me a quick research brief on the x402 payment protocol — I want web search results, a news summary, and an AI-generated explanation all in one shot.

## When to prefer this

Choose this endpoint when you need a fast, all-in-one research brief on a topic and want web search results, an AI-synthesized answer, and recent news in a single paid call rather than orchestrating three separate tool calls yourself. Prefer it over standalone search APIs when you want AI synthesis included, and over general LLM prompts when you need live web and news data grounding.

## Known failure modes

- Topic string is missing or empty — request rejected
- One or more sub-tools (search, answer, search-news) fails while others succeed — partial result returned with step-level status
- Payment not received or x402 handshake fails — 402 Payment Required returned
- Network timeout on underlying search or answer providers — partial or empty result for affected steps
- Topic is too vague or unsupported — low-quality or empty results from underlying tools

## How this service works

Bundled execution of the Article digest workflow - Quick research brief on any topic - web search results plus an AI-generated answer in one pass. One x402 payment runs 3 underlying tools (search, answer, search-news); partial-success per step.

## Output

A bundled research brief containing: web search results for the topic, an AI-generated synthesized answer, and recent news search results. Results are returned per-step with partial-success supported, so some steps may succeed even if others fail.
