# pub.dev API > The pub.dev registry — home of the Dart and Flutter package ecosystem — as an API. Look up any package for its description, latest version, repository, documentation and homepage links, Dart SDK constraint, whether it is a Flutter package, its dependencies and recent version history; search the registry by keyword (sorted by relevance, popularity, likes, points, downloads or recency); and read a package's popularity score — its like count, pub points out of the maximum, popularity percentage and 30-day download count. Live from the official pub.dev API. Ideal for package dashboards, dependency and supply-chain tooling, Flutter developer portals and ecosystem analytics. Open data from pub.dev. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
