Api Endpoint

Superhighway

One-call web research for AI agents: searches the live web AND reads the top result pages as clean markdown — content, not just links. Give a question, get ranked results plus the full readable text of the best pages. Optional ?domains=nih.gov,pubmed.ncbi.nlm.nih.gov to restrict page reading to specific sources. Pay-per-call in USDC via x402 — no signup, no API key. Use for answering questions from fresh sources, research, and RAG.
