Authority-ranked, fresh results across multiple indexes — built for context windows, not browsers.
One key, one endpoint. Search the open web, pull any URL to clean Markdown, or go paper-deep on arXiv.
Search across any index we cover. Ninelayer returns authority-ranked, typed evidence packets — extracted and ready for a context window.
Point it at any page. No cookie banners, no nav bars, no ad scripts — just the content.
Built for agents doing literature review — not casual browsing.
All three run over MCP (mcp.ninelayer.in) or a single stateless HTTP call. Markdown by default — JSON is available too, if your pipeline prefers it.
Four things a raw search API can't give an agent — shown, not claimed.
Every result is scored and tiered by source authority — official docs before forum threads, every time.
You pay for the answer, not the ad scripts and nav bars your agent would otherwise tokenize.
Indexes refresh continuously, so agents reason over what's true right now.
Compact Markdown your agent can act on. No browser rendering, no scraping loop.
"Dynamic APIs opt routes out of the full route cache by default."
The same authority-ranked results, wherever your agent runs.
Turn a broad question into a sourced brief — primary sources first, citations attached.
Check current docs and migration notes before an agent edits code. Fewer hallucinated APIs.
Watch docs, changelogs, and release notes for material changes. Skip the noise.
Ground a support agent in current documentation before it answers.
Evaluate tools or vendors using official sources, not marketing pages.
One layer,
every workflow.
Same evidence packets, from research to support.
Two indexes are online now. Here's exactly what they cover.
Official documentation and package registries (PyPI, npm, and more) across major frameworks and vendors.
arXiv papers, searchable at the paper level — abstracts, authors, and citation counts included.
Tell us what you need indexed — we'll evaluate it for the next release.
