Maven Central

Returns component versions that Central has classified under one of its topic categories, ranked by how widely the publishing group is used, with coordinates, publish time, licenses and popularity counts.

Looks up the SHA-1 hash of a published file in the Solr index and returns the exact groupId, artifactId, version, packaging and publish timestamp it belongs to.

Returns Central's summary record for a groupId:artifactId without pinning a version: latest version and its publish time and licenses, project name and description, topic categories, packaging, the file extensions published alongside the jar, upstream project/SCM/issue-tracker/CI URLs, a quality score, and how many applications and organisations use the group.

Returns the published component versions that declare a dependency on one exact artifact version, ranked by how widely the depending group is itself used, each row carrying its coordinates, publish time, licenses and popularity counts.

Returns a page of Maven Central namespaces (groupIds) ordered by the number of applications that depend on them, each with its topic categories, named contributors with their email addresses, how many artifacts the namespace publishes, and the count of applications and organisations using it. Namespace rows carry no publish date, version or licence - those fields come back null.

Returns an artifact's versions in descending version order from Central's browse index, each with its publish time in epoch milliseconds, declared licenses and project name.

Searches the Maven Central Solr index and returns matching artifacts with groupId, artifactId, latest version, packaging, available classifiers and the last publish timestamp.

Returns the full record for one exact published version: POM description and properties, parent POM coordinates, declared licenses, packaging, the classifiers and file extensions that were published, the complete list of fully-qualified class names inside the jar, named contributors, how many other components depend on it, a Sonatype quality score, and the repo1.maven.org directory URL for that version.

Returns one Solr document per published version of a single groupId:artifactId, each with its version string, packaging, bundled classifiers and publish timestamp.
