## 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 losbeto-research-brief-ai-synthesized-web-research-54fdc01d
```

Example prompt: Can you pull together a research brief on the current state of Brazil's inflation and central bank policy — I need key points and sources?

## When to prefer this

Choose this endpoint when you need a synthesized, cited research brief from live web sources on any topic — especially useful for market research, macro economic questions, financial news, or general knowledge queries where you want AI-curated key points rather than raw search results. It is well-suited for conversational agents and research bots that need to answer open-ended questions without managing their own web search pipeline. Prefer it over raw market data endpoints when narrative synthesis and source attribution matter more than raw numbers.

## Known failure modes

- Query parameter 'q' missing — returns 400 or error response
- Payment not completed via x402 — returns 402 Payment Required before content is served
- No relevant web sources found for the query — may return empty or low-quality brief
- Ambiguous or very short queries may yield generic or unfocused results
- Rate limits or upstream web crawl failures could cause timeouts
