How this service works
New releases of tracked Java/Maven packages (spring-boot, guava, commons-lang3, jackson-databind, and more) on Maven Central (Java) since a timestamp — each tagged new_release or breaking_change (major-version bump) with a 1-10 significance score. Answers "did a dependency in my pom.xml / build.gradle ship a new or breaking version I should pin or upgrade?" Pass ?package=<name> for ANY Java/Maven package on demand.
Output
A JSON object with a count, source identifier, and an array of change records — each containing a type (new_release or breaking_change), title, summary, significance score (1-10), entityId, detectedAt timestamp, effectiveDate, and a sourceUrl for verification.
Example use cases
Example prompt
“Show me all new releases and breaking changes for org.springframework.boot:spring-boot-starter since 2025-01-01T00:00:00Z, and only include ones with a significance score of at least 7.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/maven/changesWhen to prefer
Use this endpoint when you need to monitor Java/Maven ecosystem packages for new releases or breaking changes (major version bumps) with a structured significance score, especially when you want on-demand lookup of any Maven Central package by name. Prefer over generic RSS feeds or GitHub watch notifications when you need machine-readable change metadata with severity scoring.
Side effects
- Unknown or misspelled package name returns empty changes array
- Missing or malformed 'since' timestamp causes a 400 Bad Request
- Package not yet tracked may trigger a live fetch with added latency
- min_significance filter too high returns zero results
- Rate limiting or upstream Maven Central unavailability may cause 5xx errors
- Payment not provided or invalid results in 402 Payment Required
