Semantic Version Tools (semver-tools)
x402
Semantic Version Tools (semver-tools) is a paid API for AI agents from api.24klabs.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Parses, compares, validates, and bumps semantic version strings, including range testing with operators like ^, ~, >=, and <.

How this service works
Parse a semantic version, compare two versions, test a version against a range (^, ~, >=, <, exact), and compute the next major/minor/patch bump.
Output
Returns parsed version components (major, minor, patch, pre-release, build metadata), a boolean indicating whether a version satisfies a given range, a comparison result indicating which version is greater, and the computed next version string after a major/minor/patch bump.
Example use cases
Dependency compatibility check
“Check if version 4.2.1 of a package satisfies the version range >=4.0.0 <5.0.0 — I need to know if it's safe to use before I update my lockfile.”
Automated release version bump
“I just shipped a minor feature release from version 1.8.3 — what should the next version number be, and can you parse out the major, minor, and patch components of the result?”
Compare two package versions
“I have two versions of the same library: 3.11.0-rc.1 and 3.10.5 — which one is newer and by how much?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/semver-toolsWhen to prefer
Choose this endpoint when you need reliable, standards-compliant semver parsing, comparison, or range checking in an automated pipeline — especially when your agent must make release decisions, validate dependency compatibility, or compute next versions without relying on a local runtime like Node.js or a semver library.
Side effects
- Invalid semver string returns a parse error
- Unsupported range operator causes a validation failure
- Missing required input fields returns a 400 bad request
- Malformed range expression (e.g. unclosed bracket) causes parsing rejection
