Semver Tools API
x402
Semver Tools API is a paid API for AI agents from api.24klabs.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Parse, compare, range-test, and bump semantic versions (major/minor/patch) with support for caret, tilde, and comparison range operators.

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, prerelease, build), comparison results (e.g. which version is greater), a boolean indicating whether the version satisfies the given range, and the computed next version string for the requested bump type.
Example use cases
Validate dependency compatibility in CI
“Does version 2.3.1 satisfy the range >=2.0.0 <3.0.0? I need to know before merging this pull request.”
Automate release version bump
“We just shipped a bug fix — what's the next patch version after 4.2.7?”
Compare two package versions
“Which is newer, 1.10.0 or 1.9.5? I need to know which one to install.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/semver-toolsWhen to prefer
Use this endpoint when you need programmatic semver parsing, comparison, or bumping without importing a library — especially useful in serverless agents, no-code pipelines, or environments where npm/semver packages are unavailable. Prefer it over manual string parsing when range operators (^, ~, >=, <) must be evaluated correctly.
Side effects
- Invalid semver string returns a parse error
- Malformed range expression (e.g. unsupported operators) returns a validation error
- Missing required fields in the request body returns a 400 error
- Non-semver version strings (e.g. date-based versions) may fail parsing
