Notes

No account is needed. This site currently searches profiles, not the full publication directory. Some profiles have no primary publication, so its name and subdomain can be absent. The bio is the profile's description, and the subscriber count is a display string, sometimes not a number. Results are the first page. Reading posts, comments, and paid content is not supported.

About these operations

Each operation is a request learned from Substack's own web pages: API Anything replays it over plain HTTP and falls back to a browser when it must. Read them as JSON.
