## 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 crawl-web-search-api-3df45cdf -d '<json body>'
```

Example prompt: Search the web for the latest headlines about renewable energy policy and give me 5 results.

## When to prefer this

Choose this endpoint when you need live web search or scraping without API keys, subscriptions, or rate-limit agreements — especially in autonomous agent workflows where pay-per-request USDC billing via x402 is preferred over monthly subscription models. Good for ad-hoc lookups where you don't want to manage credentials.

## Known failure modes

- Payment failure if USDC balance is insufficient for x402 transaction
- Empty or irrelevant results if query is too vague
- Query parameter missing returns validation error
- Rate limiting or timeouts for very broad queries
- num parameter out of range may cause unexpected result counts
