How this service works
Hex package info - latest Elixir or Erlang package version, licenses, downloads, owners, retirements and mix.exs dependency snippet
Output
A JSON object containing the package's latest version string, list of licenses, total and recent download counts, list of owner handles, retirement status and reason if applicable, and a ready-to-paste mix.exs dependency snippet.
Example use cases
Add dependency to Elixir project
“I'm starting a new Elixir project and want to add Ecto as a database wrapper — can you look up the latest version on Hex and give me the exact mix.exs snippet to paste in?”
Check if a package is retired
“Before I use the Poison JSON library in my Elixir app, can you check on Hex if it's been retired or deprecated and what license it's under?”
Audit package ownership and downloads
“Can you pull up the Hex registry info for Oban — I want to know who the owners are and how many total downloads it has to gauge how widely used it is?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/registry/hex/:name?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative Hex.pm package metadata for Elixir or Erlang libraries — especially when you need the exact mix.exs snippet, retirement status, or owner information that generic search engines won't surface. Prefer this over scraping hex.pm directly or using npm/PyPI lookup endpoints which cover different ecosystems.
Side effects
- Package name not found on Hex — returns 404 or empty result
- Typo in package name yields no match
- Package exists but has no published releases — incomplete data returned
- Rate limiting or payment failure returns error before data is delivered
