Developer & agent resources
Units (units.school) is an AI-native online high school for earning accredited Ontario OSSD credits. This page lists everything on the site built for machines: crawlers, AI agents, and developers.
Machine-readable endpoints
llms.txt
Curated overview of Units for LLMs and AI agents — what the product is, pricing, and the pages worth reading, per the llmstxt.org convention.
sitemap.xml
Every indexable URL on units.school, including individual course pages.
robots.txt
Crawler allow/disallow rules. All public marketing and course pages are crawlable.
Markdown content negotiation
Every public page on units.school supports the Accept: text/markdown convention. Send an Accept: text/markdownheader to any public URL and you'll get a clean markdown rendition of that page with Content-Type: text/markdown; charset=utf-8 and Vary: Accept. Nonexistent paths return a real HTTP 404 with a markdown body that points back to this page, the sitemap, and llms.txt.
Public API
Units does not offer a public API, webhooks, or an MCP server yet. If you are building on top of Units — an agent, a counselor tool, a school integration — email support@units.school and tell us what you need.
