How this service works
New releases of tracked Elixir/Erlang Hex packages (phoenix, ecto, plug, phoenix_live_view, and more) on Hex.pm (Elixir) 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 mix.exs ship a new or breaking version I should pin or upgrade?" Pass ?package=<name> for ANY Elixir/Erlang Hex package on demand.
Output
A JSON object containing a count, source label, and an array of change records — each with a type (new_release or breaking_change), title, summary, significance score (1–10), entityId, detectedAt timestamp, effectiveDate, and a sourceUrl link to the original release or changelog.
Example use cases
Audit mix.exs for breaking changes
“Look through my mix.exs dependencies and tell me if any of them — especially Ecto, Plug, or Phoenix LiveView — have had breaking changes or major version bumps since last Monday. Flag anything with a significance score of 7 or higher so I know what to prioritize.”
Weekly Hex package release digest
“Give me a summary of all new releases across the phoenix, ecto, plug, and nx Hex packages from the past 7 days. I want to see what shipped, whether anything is a breaking change, and how significant each update is so I can decide what to upgrade this sprint.”
Monitor Cowboy major version bumps
“Has the cowboy Erlang package on Hex.pm released any new major versions or breaking changes since 2024-06-01T00:00:00Z? I want to know if we need to update our pinned version before it causes compatibility issues downstream.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/hex/changesWhen to prefer
Use this endpoint when you need structured, significance-scored release and breaking-change data for any Elixir or Erlang package on Hex.pm, especially when you need to filter by recency (since timestamp) or severity (min_significance). Prefer this over manually scraping Hex.pm or GitHub releases when you want machine-readable change metadata with breaking-change detection already done.
Side effects
- Unknown or misspelled package name returns empty changes array or error
- Invalid ISO-8601 format for 'since' parameter returns a 400 validation error
- Package not yet tracked and live fetch fails returns empty result or timeout
- min_significance out of 1–10 range causes schema validation error
- limit out of 1–500 range causes schema validation error
