## 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 brave-search-via-locus-x402-80da5ddc -d '<json body>'
```

Example prompt: Search Brave for the latest news on quantum computing breakthroughs from the past 7 days — give me 10 results with a summary, filtered to news only, in English.

## When to prefer this

Choose this endpoint when you need privacy-respecting, independent web search results that aren't filtered through Google or Bing's indexes. It is especially valuable when you need fresh news (with freshness filters), regional results (country-specific), or an AI-generated summary alongside raw links. Prefer it over general scraping tools when structured result types (news, video, discussions) are needed in a single call, and when paying per-query via x402 micropayments is acceptable.

## Known failure modes

- Query exceeds 400 characters or 50 words — request rejected
- Invalid country code or language code — may return default or error
- Offset out of range (>9) — no results returned
- Payment failure via x402 protocol — request not processed
- Empty results for highly niche or very recent queries not yet indexed
- Rate limiting if too many requests are made in rapid succession

## How this service works

Independent web search — web, news, images, videos, AI answers, and LLM context. Privacy-first search from a large independent index.

## Output

Returns a JSON object containing web search results from Brave's independent index, which may include web page listings, news articles, video results, discussion threads, FAQs, infoboxes, and an optional AI-generated summary. Also includes payment settlement details (USDC amount) and a request tracking ID with a status URL.
