AgentsToolsHub SemVer Checker
x402
AgentsToolsHub SemVer Checker is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).
Parses a semantic version string, tests it against a SemVer range, and compares two versions to determine the upgrade class (major/minor/patch/prerelease) — deterministically, no LLM approximation.

How this service works
Parse a semantic version into major/minor/patch/prerelease, test it against a SemVer range (^, ~, >=, *) and compare two versions with the exact upgrade class (major/minor/patch/prerelease). Deterministic — no approximating precedence rules from memory. Use this when an agent needs to parse, compare and range-test versions.
Output
Returns the parsed components (major, minor, patch, prerelease) of the given version, a boolean indicating whether it satisfies the provided range expression, and if a compareTo version is supplied, the exact upgrade class (major/minor/patch/prerelease) between the two versions.
Example use cases
Dependency range check in CI pipeline
“Does version 3.1.4 satisfy the semver range ~3.1.0? I need to know before merging this dependency update.”
Classify upgrade type between releases
“Compare 1.5.0 to 2.0.0 and tell me whether that's a major, minor, or patch upgrade so I know if it could break our app.”
Parse prerelease version for display
“Break down the version string '4.0.0-alpha.3' into its major, minor, patch, and prerelease parts for me.”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/dev/semver-checker?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, rule-correct SemVer parsing and range matching — especially when you cannot trust an LLM to correctly apply SemVer precedence rules (e.g. prerelease ordering, caret vs tilde semantics). Prefer it over asking an LLM directly for any version comparison where correctness is critical, such as CI/CD gates, dependency resolution checks, or release automation.
Side effects
- Invalid version string returns a parse error
- Malformed range expression (e.g. unsupported operator) returns a range parsing error
- Missing required 'version' query parameter returns a 400-level error
- Version strings that don't conform to SemVer spec may fail to parse
