Getting package data

Using the Composer v1 metadata

This is the preferred way to access the data as it is always up to date, and dumped to static files so it is very efficient on our end.

You can also send If-Modified-Since headers to limit your bandwidth usage and cache the files on your end with the proper filemtime set according to our Last-Modified header.

There are a few gotchas though with using this method:

• It only provides you with the package metadata but not information about the maintainers, download stats or github info.
• It contains providers information which must be ignored but can appear confusing at first. This will disappear in the future though.

GET https://repo.packagist.org/p/[vendor]/[package].json

{
  "packages": {
    "[vendor]/[package]": {
      "[version1]": {
        "name": "[vendor]/[package],
        "description": [description],
        // ...
      },
      "[version2]": {
        // ...
      }
      // ...
    }
  }
}

Working example: https://repo.packagist.org/p/monolog/monolog.json

Using the API

The JSON API for packages gives you all the infos we have including downloads, dependents count, github info, etc. However it is generated dynamically so for performance reason we cache the responses for twelve hours. As such if the static file endpoint described above is enough please use it instead.

GET https://packagist.org/packages/[vendor]/[package].json

{
  "package": {
    "name": "[vendor]/[package],
    "description": [description],
    "time": [packagist package creation datetime],
    "maintainers": [list of maintainers],
    "versions": [list of versions and their dependencies, the same data of composer.json]
    "type": [package type],
    "repository": [repository url],
    "downloads": {
      "total": [numbers of download],
      "monthly": [numbers of download per month],
      "daily": [numbers of download per day]
    },
    "favers": [number of favers]
  }
}

Working example: https://packagist.org/packages/monolog/monolog.json
