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 delx-commerce-semver-compare-abed129c -d '<json body>'
```

Example prompt: Compare semver versions 1.9.3 and 2.0.1 and tell me which one is greater.

## When to prefer this

Choose this endpoint when you need a correct, spec-compliant semver comparison without installing a library or running local code — especially useful in agent workflows where you need a trustless, pay-per-result microcomputation at $0.001 USDC with no account setup required. Prefer it over rolling your own string comparison logic, which commonly fails on cases like 1.10.0 vs 1.9.0.

## Known failure modes

- Malformed semver strings (e.g. missing patch component) may cause a 400 or unexpected result
- Pre-release identifiers (e.g. 1.0.0-alpha vs 1.0.0) may not be handled correctly if spec deviates from semver 2.0
- Payment failure via x402 protocol results in 402 response and no computation
- Empty or null version fields will likely cause a validation error
- Non-standard version formats like 'v1.2.3' with prefix may be rejected

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object indicating the ordering relationship between the two provided semantic version strings — typically whether version A is greater than, less than, or equal to version B.
