## 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 superhighway-web-search-for-ai-agents-71f4ea0c
```

Example prompt: Search the live web for the latest news about OpenAI's new model releases and return 5 results as clean markdown so I can read them.

## When to prefer this

Choose this endpoint when an AI agent needs real-time web data, recent news, or needs to read the content of a specific URL as clean markdown — especially in agentic workflows where up-to-date information is required and the x402 pay-per-call model is acceptable. Prefer over static datasets or cached search APIs when freshness matters.

## Known failure modes

- Invalid or unreachable URL returns an error or empty content
- Search query returns zero results for very niche or obscure topics
- Rate limiting if call volume exceeds free tier or paid quota
- Paywalled or bot-blocked pages may return incomplete or no content
- Count parameter outside 1–100 range may return a validation error
