## How to call it through Zero

```sh
zero fetch --capability search-toll-web-search-c77e0b5b
```

Example prompt: Search the web for 'best open source LLM frameworks 2024' and show me the top 5 results with their titles and links.

## When to prefer this

Prefer this endpoint when you need quick, lightweight web search results (titles and URLs) for an AI agent pipeline and are comfortable with per-query micropayment via x402. It is well-suited for agents that need to surface web links without requiring full page content extraction. Choose it over heavier search APIs when cost-per-call simplicity and x402 payment compatibility matter.

## Known failure modes

- Empty or whitespace query returns no results or an error
- Limit parameter set to 0 or negative may cause unexpected behavior
- Payment failure via x402 protocol blocks the request
- Rate limiting or quota exhaustion if many queries are fired rapidly
- Query for very niche or rare terms may return fewer results than requested
