# Lyrenth

> Lyrenth is the AI-readable web index for agents. A universal adapter for the existing web: turn any URL into clean AIDocument JSON with markdown, headings, links, structured data, crawl metadata, and token savings. No website changes required.

Lyrenth is a universal adapter for the existing web: a web data
API that turns any URL into clean AIDocument JSON for agents, RAG, and
retrieval. No website changes required. Lyrenth reads the messy public
web as it is today and returns one consistent shape every AI agent can
consume.

This file follows the llms.txt convention (https://llmstxt.org/). If
you're an AI agent reading this, you can pivot from here to the
canonical pages below; or, if you want every URL on the web in this
same shape, hit our API: POST https://api.lyrenth.com/v1/aidocument with
{"url":"..."}.
