## 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 srch-best-live-web-search-2ba4dac6 -d '<json body>'
```

Example prompt: Search the web for the latest news about OpenAI's GPT-5 release — use the 'deep' search type, filter to 'news' category, limit to results published after January 1 2025, and return 10 results.

## When to prefer this

Choose this endpoint when you need live, real-time web search results with fine-grained control over result depth, category (news, company, research paper, people, financial report, personal site), domain filtering, and date ranges. Prefer it over static knowledge bases when freshness matters. The x402 micropayment model ($0.0035/call) makes it cost-effective for high-frequency agent workflows needing current web data without a subscription.

## Known failure modes

- Query too short or empty — minimum 1 character required
- numResults exceeds maximum of 100
- Invalid country code — must be 2-letter ISO format
- Invalid date-time format for date range filters
- Payment failure via x402 protocol — insufficient USDC balance
- Invalid search type enum value
- Stream mode errors if real-time connection is dropped
