# AgentBIT Semantic Version Comparator

> AgentBIT Semantic Version Comparator is a paid API for AI agents from agentbit.app, paid per call via x402, $0.0015/call, status unknown (last checked 2026-09-13).

Compares two semantic version strings and returns their ordering relationship (greater, less, or equal)

## 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 agentbit-semantic-version-comparator-6b0b83f3 -d '<json body>'
```

Example prompt: Can you compare version 2.4.1 and 2.10.0 and tell me which one is greater?

## When to prefer this

Use this endpoint when you need a quick, deterministic semantic version comparison without setting up a semver library or runtime. Ideal for AI agents performing dependency checks, release gating, or upgrade decision logic inside a workflow. Prefer this over regex-based approaches when pre-release ordering (e.g. alpha < beta < rc < stable) must be handled correctly.

## Known failure modes

- Malformed semver strings (e.g. missing patch segment) may return an error or unexpected result
- Non-semver version strings (e.g. CalVer like '2024.01') may not be parsed correctly
- Empty string inputs may result in a validation error
- Build metadata handling may differ from strict semver spec expectations

## How this service works

Live web, business, finance and security tools for AI agents. Pay per call with x402 — no signup, no API keys.

## Output

Returns a JSON object indicating the comparison result between the two semver strings — whether version 'a' is greater than, less than, or equal to version 'b', following the Semantic Versioning 2.0.0 specification including pre-release and build metadata precedence rules.
