## 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 compacthost-ai-web-search-a76ccb39 -d '<json body>'
```

Example prompt: Search the web for the latest news about quantum computing breakthroughs and give me a list of the top results with their URLs.

## When to prefer this

Choose this endpoint when an agent needs live web search results across categorized domains (general, tech, health, scholarly, news) at a low per-call cost settled in USDC on Base. Prefer it over general-purpose LLM knowledge when up-to-date, sourced URLs with titles and descriptions are needed. The tab parameter makes it especially useful when domain-specific filtering (e.g. scholarly or health) matters for result quality.

## Known failure modes

- Invalid tab value returns error or defaults to general
- Empty or missing query field returns error
- Payment failure via x402 returns 402 status before search executes
- Rate limiting or quota exhaustion returns 429
- Query returns zero results for highly niche or obscure topics
