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 the first version is less than, equal to, or greater than the second version, following semantic versioning precedence rules (major, minor, patch, and pre-release identifiers).
Example use cases
Dependency upgrade decision check
“I need to know if version 3.2.0 of a library is newer than 3.1.11 — can you compare those two semver strings and tell me which is higher?”
Release pipeline gating
“Before we cut a release, check whether our build version 1.4.0-beta.2 is greater than, less than, or equal to the last published version 1.4.0-alpha.9.”
Package version audit
“We're auditing our dependencies — compare semver 0.9.99 against 1.0.0 and tell me which one takes precedence.”
Technical details
Endpoint
GEThttps://acp-x402-scriptmasterlabs.onrender.com/x402/semver-compare?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a pay-per-call, zero-infrastructure semver comparison without deploying your own logic, especially in agentic workflows that already use x402 USDC micropayments on Base. It is ideal when comparing versions programmatically as part of a release pipeline, dependency audit, or package management workflow and you want a reliable, standards-compliant result without importing a semver library.
Side effects
- Invalid or malformed version string returns an error response
- Missing required version parameters returns a 400-style error
- Payment not settled via x402 results in a 402 Payment Required response before the comparison is processed
- Ambiguous pre-release label formats may yield unexpected ordering results
