# CoCo Semver Comparison Tool

> CoCo Semver Comparison Tool is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Compares two semantic version strings and returns their relationship, numeric difference indicator, and version component difference type

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 coco-semver-comparison-tool-a51727f6
```

Example prompt: Compare these two versions for me — is 1.2.3 older or newer than 1.3.0, and is the difference a major, minor, or patch change?

## When to prefer this

Use this endpoint when you need a quick, deterministic semantic version comparison with structured output including the difference type (major/minor/patch). Prefer this over string comparison or custom logic when you need both ordering (-1/0/1) and semantic classification of the version gap in a single call.

## Known failure modes

- Invalid or non-semver strings may produce unexpected results or errors
- Missing required query parameters a or b returns a malformed request error
- Pre-release or build metadata semver variants may not be fully supported
- Network or service unavailability returns a non-200 HTTP error

## Output

Returns a JSON object containing both input versions (a, b), a numeric compare value (-1, 0, or 1 indicating a < b, a == b, or a > b), a human-readable 'meaning' string (e.g. 'a < b'), and a 'difference' field indicating the version component type of the change (e.g. 'major', 'minor', 'patch').
