How this service works
Parse a semantic version, or compare two (a vs b → -1/0/1, with greater/lesser flags).
Output
Returns parsed components of the version string (major, minor, patch, pre-release, etc.) and, when two versions are provided, a comparison integer (-1, 0, or 1) along with boolean greater/lesser flags indicating the ordering relationship between version a and version b.
Example use cases
Example prompt
“Can you compare these two version strings for me — is 2.4.1 greater than, equal to, or less than 2.10.0?”
Technical details
Endpoint
POSThttps://agent402.tools/api/semverWhen to prefer
Use this endpoint when you need to programmatically parse a semantic version string into structured components or compare two semver strings according to semver spec ordering rules — particularly useful in CI/CD pipelines, package managers, update checkers, or any workflow needing version ordering logic.
Side effects
- Malformed version string (e.g. 'abc' or '1.x.y') may return a parse error
- Missing required field 'a' returns a validation error
- Non-semver format strings may fail to parse correctly
- Network or payment authorization failure returns HTTP 402 or 5xx
