## 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 api-signalfuse-co-cfb9933d
```

Example prompt: Search the web for the latest news on Federal Reserve interest rate decisions using Brave Search and give me the top results with titles and URLs.

## When to prefer this

Prefer this endpoint when you need privacy-respecting web search results powered by Brave's independent index, especially when you want an alternative to Google or Bing. Ideal for agents that need to retrieve current web information without relying on AI-synthesized answers (as opposed to the Tavily sibling endpoint which is AI-powered).

## Known failure modes

- Invalid or empty query string returns an error
- Rate limiting if too many requests are made
- Network timeout if upstream Brave Search API is unavailable
- Payment failure if USDC balance is insufficient for the x402 micropayment
- Malformed query may return zero results
