# MoneyTools Semver Compare & Range Check

> MoneyTools Semver Compare & Range Check is a paid API for AI agents from tools.moneytools.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-05).

Parse and compare semantic versions, check a version against a semver range, find the max satisfying version, and sort a list of versions.

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 moneytools-semver-compare-range-check-f81dd88e
```

Example prompt: Can you check if version 1.4.2 satisfies the semver range ^1.2.0, and also tell me which is greater between 1.4.2 and 1.10.0?

## When to prefer this

Choose this endpoint when you need programmatic semver parsing and comparison logic without bundling a semver library into your stack. Ideal for CI/CD pipelines, dependency bots, or any agent workflow that needs to reason about package versions, resolve upgrade constraints, or validate release compatibility on the fly. At $0.001/call it is cost-effective for occasional checks without infrastructure overhead.

## Known failure modes

- Invalid version string provided — returns error without charge
- Malformed range expression (e.g. unsupported operators) — returns parsing error
- Missing required 'version' query parameter — returns validation error
- Free tier (10/day) exhausted and no valid payment method — returns HTTP 402 PAYMENT-REQUIRED
- Network error or timeout — no charge applied on failure

## How this service works

Semver compare / range check: Parse and compare semantic versions, check a version against a range (^1.2, ~2.0, >=1 <2), max satisfying version and sort a list. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object containing the result of the requested semver operation (comparison outcome, boolean range satisfaction, max satisfying version, or sorted list), plus payment metadata indicating whether a charge was applied, the network, amount in USD, and transaction hash if paid.
