Firmament Sky API
The public JSON service behind Firmament Sky, a free Bible reading and study application.
About this service
Firmament Sky is a Bible reading web app. This host serves the data the app runs on: the text of Scripture, structured daily reading plans, cross-references between passages, and the personal reading data (bookmarks, prayer lists, reading position) belonging to signed-in users. It is a religious and reference service. It hosts no advertising, no user-uploaded content, no file sharing, and no third-party redirects.
What it provides
- Bible books, chapters and verses, and full-text search across them
- Daily reading plans, including the M'Cheyne one-year plan
- A verse of the day
- Cross-references between related passages
- Bookmarks, reading ribbons and prayer lists for signed-in users
- Questions answered from the articles published on the Firmament Sky blog
Using it
Endpoints live under /api/ and return JSON. Endpoints that touch personal reading
data require an authenticated account; the rest are open. The API is intended for the Firmament
Sky web app rather than for general third-party use, so browser access is limited to the
application's own origins.
A liveness check is available at /api/health.
