Endpoint
POSThttps://x402.srch.best/search?utm_source=zero.xyzWhen to prefer
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.

- Invalid country code — must be 2-letter ISO format
- Invalid date-time format for date range filters
