How this service works
Compare two semantic versions for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns a comparison result indicating whether the first version is greater than, less than, or equal to the second version, based on standard semantic versioning (SemVer) precedence rules.
Example use cases
Dependency upgrade decision
“Is version 4.2.1 of this library greater than, less than, or equal to 4.2.0? I need to know if there's actually a newer release before I push an upgrade.”
CI pipeline version gate
“My build produced version 1.15.0 and the last released version is 1.14.9 — compare those two semver strings and tell me which is greater so I can decide whether to publish.”
Changelog ordering check
“I have two release tags: v3.0.0-beta.2 and v3.0.0-beta.11 — which one comes later according to semver rules?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/semver-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a reliable, standards-compliant semver comparison without implementing the logic yourself — especially in agent pipelines doing dependency resolution, release gating, or version ordering where correctness of pre-release and patch ordering matters.
Side effects
- Malformed version string (non-semver input) returns an error
- Missing one or both version parameters returns a validation error
- Pre-release and build metadata edge cases may produce unexpected results if inputs are not valid semver
- Payment of $0.001 USDC required per call via x402; missing or failed payment returns 402 status
