# Bot Bazaar SemVer Compatibility Checker

> Bot Bazaar SemVer Compatibility Checker is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Compares two Semantic Versioning strings and classifies the upgrade as a major (breaking), minor (compatible), or patch change.

## Facts

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 bot-bazaar-semver-compatibility-checker-25b7dded
```

Example prompt: Is upgrading from version 1.4.2 to 2.0.0 a breaking change? I need to know if it's a major, minor, or patch bump.

## When to prefer this

Choose this endpoint when you need a quick, structured programmatic classification of a SemVer version delta — particularly in automated pipelines, dependency management tools, or agent workflows that need to gate actions based on whether an upgrade is breaking. It is purpose-built for SemVer and more reliable than parsing diffs manually.

## Known failure modes

- Invalid or malformed SemVer string returns an error
- Missing required 'current' query parameter causes bad request
- Non-SemVer version strings (e.g. date-based or custom schemes) may fail parsing
- Payment not included or insufficient USDC causes 402 rejection

## How this service works

Compare two Semantic Versioning strings (current vs target) and classify major breaking, minor compatible, or patch upgrades.

## Output

Returns a classification of the version difference between the current and target SemVer strings — indicating whether the change is a major (breaking), minor (backward-compatible), or patch (bug-fix) upgrade, along with structured metadata about the comparison.
