Can an AI agent reach the API docs from a product's home page?

101 of 119 products (85%) link their docs in the home page's HTML, one link from home for an AI agent. At 8 of 119, an agent that follows links finds no way to the docs: no link on the home page and no llms.txt that lists them.

How an agent reaches the API docs. Docs linked on the home page: 101 of 119, llms.txt lists the docs: 93 of 119, An API reference page: 100 of 119, llms.txt lists the API reference: 80 of 119, No link and no llms.txt: 8 of 119.

What to do.

For product owners

Put a plain docs link in the home page's HTML, not only in a menu a script builds.
Publish an llms.txt that lists your docs pages and your API reference.
Serve the docs at docs.yourdomain.com or yourdomain.com/docs too.

For agent builders

Read the home page's links first, then llms.txt, then try docs.<domain>, developers.<domain> and /docs.
Don't stop at a home page with no docs link: 10 of 119 products list their docs only in llms.txt.
Use llms.txt to go straight to the API reference: 80 of 119 products list it there.

Method and limits.

How we tested

On 12–13 Oct 2026 we read the home pages of the 119 products we drove, without a browser, and looked for a link to docs, developers or an API reference that opened a page.
Each product's newest drive (1 Oct 2026 to 1 Nov 2026) read its docs: the pages the home page links, docs.<domain>, developers.<domain>, /docs, llms.txt and the sitemaps.
A page counts as the API reference when its title, headings or address name it.

Limits

A docs link that a script adds after the page loads isn't in the HTML, so it counts as no link.
Each home page as it was on the day we read it; each product's docs on the day of its newest drive.
