## 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 x402-gateway-production-up-railway-app-27f82682 -d '<json body>'
```

Example prompt: Search the web for the latest trends in renewable energy in 2024 and return the top 5 results with highlighted snippets.

## When to prefer this

Use this endpoint when you need live, current web search results with highlighted snippets — especially for news, recent events, or research queries. Prefer it over static knowledge bases when freshness matters or when you need sourced URLs from real web pages.

## Known failure modes

- Query too vague or empty — returns no results or error
- Limit parameter out of allowed range — validation error
- Upstream search provider unavailable — 5xx error
- Payment not provided or invalid — 402 payment required
- Rate limit exceeded — throttling error
