## 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 pennyrail-live-web-search-be821e5c -d '<json body>'
```

Example prompt: Search the web right now for the latest news about OpenAI's new model releases and give me the top results.

## When to prefer this

Choose this endpoint when your agent needs real-time, live web search results and is operating in an x402-enabled payment environment with USDC. It is particularly useful when freshness of information matters (e.g., current events, recent product launches, live news) and when a micro-payment per search ($0.02 USDC) model is acceptable. Prefer over static knowledge bases when you need results from the open web right now.

## Known failure modes

- Payment failure if USDC balance is insufficient (x402 payment required)
- Empty or no results if query is too obscure or malformed
- Rate limiting if too many requests are made in quick succession
- Vague input object causes broad or irrelevant results
- Service unavailability if the underlying search provider is down
