# Cactus Docs and agent formats

> Verified against the product on 2026-10-06

## What Cactus does

Cactus's public site brings together Docs, What's New, AI-client instructions, pricing, company information, and legal and trust pages.

## Read Cactus Docs

Browse Cactus's public Docs at `https://heycactus.ai/docs`. The catalogue groups published pages, and each page opens from the catalogue.

## Read Docs with an agent

Cactus's public Docs are available without a sign-in, so an AI agent can read the same published pages.

## Get Markdown pages

Cactus's home page is available at `/md`. For another public Cactus page, append `/md` to its address. The Docs catalogue is at `/docs/md`, and each published Docs page is at `/docs/<slug>/md`.
