Go Modules API

healthy 3,063 Subscribers

The Go package ecosystem as an API. Look up any Go module by its import path for its latest version, license, source repository, total version count and known security advisories; read a module's full version history with publication dates; and get a module's declared dependencies — direct and indirect — parsed straight from its go.mod, with the required Go version. Covers the entire public Go module graph, from github.com/gin-gonic/gin, github.com/spf13/cobra and golang.org/x/text to gorm.io/gorm and k8s.io/client-go. Live from the official Go module proxy (proxy.golang.org) and Google's deps.dev. Ideal for dependency and supply-chain tooling, SBOM generation, package dashboards and Go developer portals. Modules are addressed by full import path. Open data.
