How this service works
New releases of tracked Dart/Flutter pub packages (http, provider, dio, riverpod, and more) on pub.dev (Dart/Flutter) 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 pubspec.yaml ship a new or breaking version I should pin or upgrade?" Pass ?package=<name> for ANY Dart/Flutter pub package on demand.
Output
A JSON array of change events, each with: entity ID, change type (new_release or breaking_change), a human-readable title and summary, a significance score from 1 to 10, a source URL for verification, and timestamps for detection and effective date. Also includes a top-level count and source field.
Example use cases
Example prompt
“Check for any new releases or breaking changes in the 'riverpod' pub package since 2025-01-01T00:00:00Z, and only show me changes with a significance score of at least 7.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/pub/changesWhen to prefer
Use this endpoint when you need to monitor Dart or Flutter pub.dev packages for new releases or breaking (major) version bumps, especially when you want significance-scored results. It supports on-demand lookup of any pub.dev package via the ?package= param, making it more flexible than polling pub.dev directly. Prefer it over generic RSS/changelog scraping when you need structured, scored change events for automation or alerting.
Side effects
- Package name not found on pub.dev — returns empty changes array or error
- Invalid ISO-8601 timestamp in 'since' — returns 400 validation error
- Payment not included or insufficient — returns 402 Payment Required
- limit or min_significance out of allowed range — returns 400 validation error
- Package not yet tracked and live-fetch fails — may return empty results or timeout
