## 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`):

Example prompt: Can you pull up to 10 recent market signals and news summaries about 'generative AI' in English? I want a quick digest of what's happening in that space right now.

## When to prefer this

Choose this endpoint when you need a fast, automated digest of recent news and market signals for a specific topic keyword, especially for tracking industry trends, brand updates, or business intelligence without manual searching. Prefer this over generic web search when you want concise, aggregated summaries rather than raw links, and when the x402 micropayment model is acceptable. Best for recurring topic monitoring or quick-turnaround briefings on evolving market themes.

## Known failure modes

- No news found for an obscure or misspelled tag — returns empty results or minimal content
- Language enum value not matching 'en-US' or 'zh-CN' — validation error
- Limit exceeds maximum of 10 — capped or rejected
- Payment not completed via x402 protocol — 402 Payment Required response
- Timeout if external news sources are slow to respond

Based on a user-specified topic, it automatically collects related information and turns scattered news into concise, focused summaries. It is suitable for tracking industry trends, market changes, brand updates, or business topics, allowing users to quickly access key information without manually searching.

## Output

A structured set of up to 10 recent news items or market signals related to the specified topic tag, returned as concise summaries in either English (en-US) or Chinese (zh-CN), suitable for quickly understanding current trends and developments.
