  ERS SHIPS NO CLIENT SDK, in any language, on any registry. What exists is a set of
  first-party code SAMPLES on GitHub - not installable libraries - last touched in 2013, plus
  one third-party R package on CRAN that has not been released since 2020. The ERS data-apis
  page still tells developers "Code snippets for the ARMS API are available in R (or REST)"
  without linking to them.

    license: GPL (>= 2)
    note: >-
      Third-party, not ERS. The only installable client for the ARMS API on any registry.
      Version 1.0.0 is the only release, dated 2020-01-23 - six and a half years old at the time
      of this check, and older than every ARMS data release from 2020 onward. Metadata read from
      https://crandb.r-pkg.org/rarms.
  - name: USDA-REE-ERS/data-apis
    registry: none
    url: https://github.com/USDA-REE-ERS/data-apis
    language: multiple
    official: true
    kind: code-samples
    version: null
    published: '2013-12-12'
    note: >-
      First-party ERS repository of API code samples - dotNet-code.md, python-code.md,
      ruby-code.md, jquery-code.md - and nothing else. NOT A PACKAGE: there is no registry
      entry, no install command, no versioning and no build; a consumer copies the snippet.
      version is null because the distribution has no version to read. Last push 2013-12-12;
      the repo homepage still points at http://www.ers.usda.gov/developer/data-apis.aspx, a URL
      the current site no longer serves. Predates the ARMS API (2019) entirely, so these
      samples describe an earlier ERS data API.

    note: >-
      First-party ERS repository holding the ARMS API README - the same prose that is on
      ers.usda.gov, with no spec, no schema and no code. Listed here because it is the only
      place ERS puts anything API-shaped under version control. Last push 2020-12-18. Its
      AllVariables.csv link still points at the December 2020 file while the live docs link the
      December 2023 one.

      "Source code for widgets using ERS APIs" - the Charts of Note widget. An embeddable UI
      surface rather than a client library; see components/economic-research-service-components.yml.
      Unpinned and unversioned; a consumer cannot tell what they would be getting. Last push
      2013-11-29.
