paket.halowerk.com/v1/package-versions

Returns the full version history of a package from a single normalised schema that covers seven ecosystems. Versions are ordered by semantic version, not alphabetically and not in registry order, so 1.10.0 sorts after 1.9.0 — the mistake that quietly breaks naive comparisons. For each version you get the publication timestamp, whether it is the registry default, whether it is deprecated and the deprecation reason as the registry states it.
