Bio Pages API
There is no bio pages API. Bio pages are created, edited, themed and published in the dashboard only.
What does not exist
/api/v1/bio-pages is not a route, in any method. Neither are its blocks, themes or view counts. An earlier version of this page documented a full CRUD interface for them; none of it was ever reachable, and requests against those paths return 404.
The pages:read and pages:write scopes are real and can be granted to an API key, but no endpoint requires either one, so granting them adds nothing today.
What the API does cover
The whole of /api/v1 is six endpoints: short links, QR codes, goals and conversions. Start from the API overview for the base URL, authentication, rate limits and error format.
One rule worth knowing if you create links programmatically: a short link on the default distribution domain may not point at a MASK bio page. The create call refuses it. Use a custom domain if you need a short link that resolves to your own bio page.
Working with bio pages
Build and publish pages in the dashboard, where the block library, the built-in templates and the theming controls live. The Bio Pages guide covers that workflow. Page view analytics are read in the analytics dashboard and in its CSV export on Growth plans and above.
