## 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 scriptmasterlabs-semver-compare-api-40246ecf
```

Example prompt: Can you compare version 1.4.2 and 1.10.0 using semver rules and tell me which one is greater?

## When to prefer this

Choose this endpoint when you need a reliable, pay-per-call semver comparison without self-hosting logic, especially in agentic pipelines that already use x402/USDC micropayments on Base and need to determine version precedence programmatically.

## Known failure modes

- Malformed or non-semver version strings return an error or unexpected result
- Missing version parameters cause bad request responses
- Service unavailability on the Render-hosted instance leads to timeout or 5xx errors
- Pre-release label edge cases (e.g. 1.0.0-alpha vs 1.0.0-alpha.1) may not be handled correctly if not well-specified

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a comparison result indicating whether version A is greater than, less than, or equal to version B according to semantic versioning (semver) specification rules, including handling of pre-release identifiers and build metadata.
