Stop building a web stack.

Over 4.4 billion pages across more than 176.2 million domains.
Give your AI broad web coverage without building and maintaining the infrastructure yourself. For agents, assistants, pipelines and knowledge bases.
Free while you build, paid when you grow.
One call per page. Answers in milliseconds from the index, and up to 99.4% fewer input tokens than raw HTML on measured pages.
We run the web index.
You ship your product.
Every page is read into the index once and served from it. Most pages you request have already been read, so yours comes back in milliseconds and the site is never touched again. The more people read through Lyrenth, the more of the web is already waiting when you arrive. When freshness matters, force_refresh re-indexes on demand.
One canonical AIDocument per URL. Written once, read by everyone: the work happens on our side, the call happens on yours.
We crawl the open web and render the pages that need a browser. It runs without you, around the clock.
One standing index in the middle: cleaned, normalized, held, and shared by every reader.
Your side is one request. Send a URL, get the document back in milliseconds. Done.

What famous pages cost,
raw vs indexed.
Every row is a real page read through the index, with token economics reported by the API itself. Reproducible with one call.
The same shape,
for every URL.
Send any public URL, get one AIDocument back: the same grouped JSON envelope every time, versioned forever. Validate against the public JSON Schema.

actually read you?
AI cannot recommend what it cannot read. Paste your URL and see exactly what an agent receives from your page: how much of it is real content, what is missing, and what to fix. Most sites have never been checked.
Try a page
your application needs to read.
No account for the first reads. Paste a URL, watch it resolve, and see what your model would receive: the same grouped JSON envelope every time, with the tokens it saved.
