## 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 blockrun-ai-2e8b2a9a
```

Example prompt: Search the web for the latest news and information about Solana's recent network upgrades — pull results from crypto sources.

## When to prefer this

Use this endpoint when you need web search results specifically filtered or optimized for cryptocurrency, blockchain, and DeFi sources, rather than a general-purpose web search. Prefer it over general search APIs when the topic is crypto-specific and you want domain-relevant results without noise from unrelated industries.

## Known failure modes

- Missing required query parameter 'q' returns a 400 error
- Empty or ambiguous query may return low-relevance results
- Payment not provided or insufficient USDC causes 402 Payment Required
- Rate limiting may occur for high-frequency requests
- Niche queries with little crypto coverage may return sparse results
