## 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 sol-blockrun-ai-ceded163 -d '<json body>'
```

Example prompt: Search the web for recent news about OpenAI's latest model releases, limit to 15 results and only look at news sources.

## When to prefer this

Use this endpoint when you need both neural (semantic/meaning-based) and keyword web search with structured category filtering. It is especially valuable when you want to restrict results to a specific content type like research papers, financial reports, tweets, LinkedIn profiles, or GitHub repositories — categories not typically available in generic search APIs.

## Known failure modes

- Invalid category filter value returns an error
- Query string missing causes 400 bad request
- numResults exceeding 100 returns an error
- Payment not provided or insufficient USDC causes 402 payment required
- includeDomains and excludeDomains conflict may return empty results
