About Substack API
from our crawl and measurement
"Welcome to Substack API, the unofficial open-source API for Substack publications." That is how Substack API introduces itself. To AI engines like ChatGPT and Perplexity it is partially visible, scoring 5.1 out of 10, readable in places, missing in others.
On the page, the fundamentals are in place: structured data on the page (WebSite, Organization, WebPage), an llms.txt file for AI models, a sitemap.
AI crawlers have visited the site once in our tracking, so the engines are already looking.
