Endpoint
POSThttps://pennyrail.vercel.app/api/p/premium/web.search--web-searchWhen to prefer
Choose this endpoint when an AI agent needs live, up-to-date web search results and is operating in an x402 micropayment environment. It is well-suited for agents that need to retrieve current information beyond their training cutoff, verify facts with fresh sources, or find URLs and content about a topic in real time. Prefer it when you are already integrated with x402 payment infrastructure and need search as a pay-per-call utility.

- Query too broad or empty — may return empty or low-quality results
