Starko developer portal

Everything you need to build against starko.one: a public OpenAPI spec, machine-readable content access, and the files AI agents use to crawl and understand this site.

API reference

This site's marketing/content endpoints are public and unauthenticated. They're documented in full, request and response shapes included, in the OpenAPI spec.

Method	Path	Description
GET	/api/md	Homepage content as Markdown. Equivalent to `GET /` with an `Accept: text/markdown` header.
GET	/api/blog-md/{slug}	A blog post's raw Markdown body with a metadata header. Equivalent to `/blog/{slug}.md`.
POST	/api/contact	Submit the contact form: `{ email, message }` as JSON.

Looking for the Starko product API (used inside the app at chat.starko.one)? That API requires a workspace and is documented separately for signed-in customers — contact us for access.
