Public API

JavaMaster Pro provides a public API for release metadata, changelog entries, installer redirects, and Velopack update compatibility.

Base URL

https://dl.javamasterpro.com

Requests

Endpoints accept GET and HEAD. Download endpoints also accept a consented website form POST and return a 303 redirect. Other methods return 405.

Endpoint	Response
`/api/healthz`	200 JSON health status.
`/api/changelog`	Public stable-release changelog as JSON.
`/api/releases/latest?platform=win-x64`	Latest public release metadata as JSON.
`/api/releases/{version}?platform=win-x64`	Versioned public release metadata as JSON.
`/api/downloads/latest?platform=win-x64`	GET returns 302; a consented website POST returns 303. Both select the latest installer or checksum.
`/api/downloads/{version}?platform=win-x64`	GET returns 302; a consented website POST returns 303 for the selected version.
`/api/updates/velopack/stable/win-x64/{fileName}`	302 redirect only for `releases.win.json` or a package referenced by that feed.

Parameters

channel is optional and currently supports stable.
platform is required for release and download endpoints: win-x64 or win-arm64.
kind applies to download endpoints and defaults to setup. Supported values: setup and checksum.
version uses semantic-version syntax.

Responses and caching

Release metadata responses include version, channel, runtime, publication date, update-feed URL, optional release notes URL, and public artifact URLs with SHA-256 checksums and byte sizes. The changelog response includes versioned desktop release summaries and categorized change lists.

Invalid requests return sanitized JSON errors. Latest responses can be cached briefly; versioned metadata and versioned GET redirects are immutable. POST download redirects are private and never cached.
