parse_version
Validate a version against SemVer 2.0.0 and split it into major, minor, patch, prerelease identifiers and build metadata, with isPrerelease/isStable flags. Read-only. Same engine as GET /api/parse.
compare_versions
Compare a and b by SemVer precedence (prereleases sort before the release, build metadata ignored). Returns -1, 0 or 1 and the change type from the lower to the higher version (major, minor, patch, premajor, preminor, prepatch, prerelease) exactly like semver.diff. Read-only. Same engine as GET /api
check_range
Does a version satisfy an npm-style range (^, ~, x-ranges, hyphen ranges, comparators, || alternatives)? Returns the answer and the range desugared into plain comparators (e.g. ^0.2.3 → >=0.2.3 <0.3.0-0), with a note when npm's prerelease rule is why it fails. Read-only. Same engine as GET /api/sati
resolve_versions
Sort 1 to 200 versions by SemVer precedence (duplicates removed, invalid ones listed separately) and, if a range is given, return the matching versions plus maxSatisfying / minSatisfying (what npm would install from that list) and the latest stable version. Read-only. Same engine as GET /api/resolve
bump_version
Compute the next version for a release type (major, minor, patch, premajor, preminor, prepatch, prerelease, release), with an optional prerelease id such as alpha, beta or rc, exactly like npm version / semver.inc. Read-only: nothing is published. Same engine as GET /api/bump.
