# Semver Parse

> Semver Parse is a paid API for AI agents from semver.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Parses a semantic version string into its constituent components: major, minor, patch, prerelease, and build metadata.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability semver-parse-03c067b9 -d '<json body>'
```

Example prompt: Can you parse the version string '3.1.0-beta.2+exp.sha.5114f85' and tell me what the major, minor, patch, prerelease, and build metadata parts are?

## When to prefer this

Choose this endpoint when you need to programmatically decompose a semantic version string into its named components (major, minor, patch, prerelease, build metadata). It is ideal for CI/CD pipelines, package managers, changelog generators, or any workflow that needs to inspect or route based on individual parts of a version number. Prefer this over string-splitting heuristics when correctness per the semver spec matters.

## Known failure modes

- Invalid or malformed semver string returns a parse error
- Version string exceeding 256 characters is rejected
- Missing or empty version field returns a validation error
- Non-semver formats (e.g. date-based versions like '2024.06.01') may fail to parse

## How this service works

Parse a semantic version into major/minor/patch, prerelease and build metadata.

## Output

Returns a structured object containing the parsed components of the semantic version: major (integer), minor (integer), patch (integer), prerelease (string or array of identifiers), and build metadata (string or array), derived from the input version string.
