## 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 swarmio-web-search-b848e477 -d '<json body>'
```

Example prompt: Search the web for 'quantum computing breakthroughs this month' and give me the top 5 results from the last month — only from reuters.com or apnews.com.

## When to prefer this

Choose this endpoint when you need fresh, domain-filtered web search results with publication dates, especially for news or research queries. It supports domain allowlisting (e.g. restricting to reuters.com) and freshness filtering (day/week/month/year), making it superior to generic search tools when source trust or recency matters. Prefer this over internal knowledge retrieval when the user needs up-to-date external web content.

## Known failure modes

- No results found for obscure or malformed queries
- Domain allowlist too restrictive — no results from specified domains
- Freshness filter excludes all available content
- Provider failure — providers_failed list non-empty, partial or no results
- Payment failure — insufficient USDC balance
- Rate limiting or quota exceeded
- Query string too long or malformed
