GENESIS Agent Tools — Semantic Version Comparison
x402
GENESIS Agent Tools — Semantic Version Comparison is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).
Compares two semantic version strings and returns a comparison result indicating their relationship

How this service works
Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.
Output
Returns a JSON object with a 'comparison' string field indicating the relationship between the two versions — typically values like 'greater', 'less', or 'equal', describing how version A relates to version B.
Example use cases
Dependency upgrade decision check
“I need to know whether version 3.0.0-beta.1 is ahead of or behind 2.9.9 in semver ordering — can you compare them?”
CI pipeline version gate
“My pipeline needs to confirm that the newly built release 1.12.0 is strictly greater than the last published version 1.11.5. Can you run that semver comparison?”
Package compatibility triage
“I'm looking at two versions of a library — 4.0.0-alpha.3 and 3.99.100 — which one is considered higher according to semver rules?”
Technical details
Endpoint
POSThttps://genesis-agent-tools.genesisagenttools.workers.dev/api/tools/semver-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs programmatic, pay-per-call semver comparison without spinning up its own parsing logic — especially within automated workflows on Base USDC using the x402 payment protocol. Prefer it over rolling custom semver logic when working in agentic pipelines that already use GENESIS Agent Tools for other API compatibility or readiness checks.
Side effects
- Malformed semver strings (e.g. missing patch segment) may return an error or unexpected comparison
- Non-semver version strings (e.g. calendar versions like '2024.01') may not parse correctly
- Missing required fields 'a' or 'b' will cause a 400-level error
- Payment failure via x402 protocol will block the request before processing
