check_clojars_version_exists
Check if a specific version of a Clojars dependency exists
LABSCO SUMMARY
A version lookup narrow enough that each question is one call: what is newest, whether a given version is real, and what came before it.
Every tool takes dependency as its unit of address, so the same coordinate carries straight through from get_clojars_latest_version to check_clojars_version_exists to get_clojars_history without re-deriving anything. The scope stops at versions — nothing here reads a project's dependency file, resolves a tree or reports vulnerabilities — which makes it an answer to "what should I pin?" rather than a dependency manager.
What it is
A lookup server over Clojars, answering version questions about a dependency given as a Maven artifact.
What you get
- get_clojars_latest_version returns the latest version of a dependency.
- check_clojars_version_exists answers whether a named version of a dependency is published, taking dependency and version.
- get_clojars_history returns a dependency's version history, bounded by limit.
Requirements
Nothing — no account, no key.
Setup effort
One command — npx -y clojars-deps-server
USE CASES
01
Pinning a dependency to a version that actually exists
Check the version you were about to write down, and take the newest published one if it does not resolve.
02
Judging whether an upgrade is worth doing yet
Read the release history to see how the versions have moved, then compare it against what you are currently on.
3 tools

get_clojars_history
Get version history of a Clojars dependency
get_clojars_latest_version
