GET /search
live
Real-time web search API for AI agents. Returns ranked organic results (title, link, snippet) as JSON from a resilient multi-engine metasearch (Bing, Brave, DuckDuckGo, Wikipedia, Mojeek). Pay-per-query in USDC via x402 — no signup, no API key, no rate limits. Built for agent grounding, research, RAG, fact-checking, and fresh real-world information.
Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
