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.
Example use cases
Dependency upgrade safety check
“I need to know if version 2.3.1 is actually newer than 2.3.0-rc.2 according to proper semver rules — can you compare them for me?”
CI pipeline version gate
“In my build pipeline I have the current release at 4.1.0 and a candidate at 4.1.1-beta.3 — which one ranks higher under semantic versioning?”
Package registry version ordering
“Can you tell me the correct semver ordering between 0.9.11 and 0.9.9 so I know which should be considered the latest?”
Technical details
Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/semver-compareWhen to prefer
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.
Side effects
- 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
