[x402 catalog slot #286] Build x402 Web Search API behind pay-gate

Highest-frequency paid endpoint in the catalog: web search (text/image/video/news/site-restricted) with real ranked results. Wrap any upstream (Brave/Serper/Tavily/own crawl) — x402 interface IS the value-add.

WHY: $5 bounty is setup. Real reward = you OWN the deployed API. Every x402 agent calling your endpoint pays YOUR Base wallet in USDC. No revenue share with us.

Submission: HTTPS URL of your API + your Base wallet address + one paid round-trip showing 402 -> 200 with real data. Verifier checks pay request returns 402, paid request returns real data, pay discover finds it, info blocks filled, no fake/static responses.

settlement: "tab" required (micropayments).
