Client Input

rubygems /api/v1/dependencies was deprecated upstream in 2023; use the Compact Index (versions, names, info/{name}), /api/v1/versions/{name}.json, or the legacy Marshal indexes (specs.4.8.gz) instead

Default message: rubygems /api/v1/dependencies was deprecated upstream in 2023; use the Compact Index (versions, names, info/{name}), /api/v1/versions/{name}.json, or the legacy Marshal indexes (specs.4.8.gz) instead
HTTP status: 410 (client)
Reason: UPSTREAM_DEPRECATED

Problem. A request to /api/v1/dependencies through the RubyGems proxy returns HTTP 410 Gone. Cause. RubyGems.org deprecated the Dependency API in February 2023. Upstream answers with a 404 and a text/plain body; the proxy rewrites that into a 410 with a structured CHW envelope so the failure is machine-readable and points at the working successors. Fix. Move the client onto one of the supported index endpoints:

  • the Compact Index — versions, names, info/{name} (what Bundler ≥ 1.12 uses by default),
  • /api/v1/versions/{name}.json for a single gem’s version list, or
  • the legacy Marshal indexes — specs.4.8.gz, latest_specs.4.8.gz, prerelease_specs.4.8.gz.

In practice only a very old Bundler or a bespoke script still calls the Dependency API; upgrading Bundler resolves it. HTTP 410.
