How this service works
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.
Output
A normalized, semantically-sorted list of all released versions of the specified package, each entry containing: version string, publication timestamp, whether it is the registry default, whether it is deprecated, and the deprecation reason if applicable. Covers seven package ecosystems under a single unified schema.
Example use cases
Auditing deprecated package versions
“Can you pull the complete version history for 'requests' on PyPI and highlight every version that's been marked as deprecated, including the reason the registry gave?”
Finding the canonical default release
“I need to know which version of the 'lodash' npm package is currently the registry default — can you fetch the full version list sorted properly by semver so I can see it in context?”
Checking publication timeline for a NuGet package
“Get me the release history for 'Newtonsoft.Json' on NuGet with exact publication timestamps, sorted by semantic version — I want to see when each major version came out.”
Technical details
Endpoint
POSThttps://paket.halowerk.com/v1/package-versionsWhen to prefer
Choose this endpoint when you need a complete, semantically-correct version history of a package rather than just the latest version. It is especially valuable when naive alphabetical or registry-order sorting would mislead (e.g. 1.10.0 vs 1.9.0), when you need to identify deprecated versions and their reasons, or when you need to work across multiple ecosystems using a single normalized schema. Prefer it over raw registry APIs when correctness of semver ordering matters for downstream automation.
Side effects
- Unknown package name returns 404 or empty version list
- Unsupported ecosystem returns validation error
- Registry temporarily unavailable causes upstream timeout
- Malformed package identifier returns 400 bad request
- Payment failure via x402 blocks the request before execution
