How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
Clean markdown content extracted from the top web pages matching the query, including recent news and live web results, limited to 1–3 pages as specified
Example use cases
Example prompt
“Search the live web for the latest news on OpenAI's GPT-5 release — read the top 3 results and give me the content as clean text, focusing only on pages from techcrunch.com and theverge.com.”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/research?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs live, up-to-date web information that is not available in a training dataset — especially for recent news, current events, or domain-restricted research. Prefer this over static knowledge bases when freshness matters, and over general scraping tools when you want clean markdown output ready for LLM consumption at a low per-call cost.
Side effects
- No results found for the query — empty or minimal response
- Requested domains in allowlist have no matching results, falls back to all results
- Query parameter missing — returns 400 error
- Rate limit or payment failure — returns 402 payment required
- Target page is paywalled or inaccessible — partial or no content returned
- Pages value out of range (less than 1 or greater than 3) — returns validation error
